* This is a legacy parameter, for backward compatibility. New applications * should use ConditionExpression instead. Do not combine legacy * parameters and expression parameters in a single API call; otherwise, * DynamoDB will return a ValidationException exception. *

*
*

* A map of attribute/condition pairs. Expected provides a * conditional block for the PutItem operation. *

* *

* This parameter does not support attributes of type List or Map. *

*
*

* Each element of Expected consists of an attribute name, a * comparison operator, and one or more values. DynamoDB compares the * attribute with the value(s) you supplied, using the comparison operator. * For each Expected element, the result of the evaluation is either * true or false. *

*

* If you specify more than one element in the Expected map, then by * default all of the conditions must evaluate to true. In other words, the * conditions are ANDed together. (You can use the * ConditionalOperator parameter to OR the conditions instead. If you * do this, then at least one of the conditions must evaluate to true, * rather than all of them.) *

*

* If the Expected map evaluates to true, then the conditional * operation succeeds; otherwise, it fails. *

*

* Expected contains the following: *

*
    *
  • *

    * AttributeValueList - One or more values to evaluate against the * supplied attribute. The number of values in the list depends on the * ComparisonOperator being used. *

    *

    * For type Number, value comparisons are numeric. *

    *

    * String value comparisons for greater than, equals, or less than are based * on ASCII character code values. For example, a is greater * than A, and a is greater than B. * For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters. *

    *

    * For type Binary, DynamoDB treats each byte of the binary data as unsigned * when it compares binary values. *

    *
  • *
  • *

    * ComparisonOperator - A comparator for evaluating attributes in the * AttributeValueList. When performing the comparison, DynamoDB uses * strongly consistent reads. *

    *

    * The following comparison operators are available: *

    *

    * EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN *

    *

    * The following are descriptions of each comparison operator. *

    *
      *
    • *

      * EQ : Equal. EQ is supported for all datatypes, * including lists and maps. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, Binary, String Set, Number Set, or Binary * Set. If an item contains an AttributeValue element of a different * type than the one provided in the request, the value does not match. For * example, {"S":"6"} does not equal {"N":"6"}. * Also, {"N":"6"} does not equal * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * NE : Not equal. NE is supported for all * datatypes, including lists and maps. *

      *

      * AttributeValueList can contain only one AttributeValue of * type String, Number, Binary, String Set, Number Set, or Binary Set. If an * item contains an AttributeValue of a different type than the one * provided in the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. Also, * {"N":"6"} does not equal {"NS":["6", "2", "1"]} * . *

      *

    • *
    • *

      * LE : Less than or equal. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If an item * contains an AttributeValue element of a different type than the * one provided in the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. Also, * {"N":"6"} does not compare to * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * LT : Less than. *

      *

      * AttributeValueList can contain only one AttributeValue of * type String, Number, or Binary (not a set type). If an item contains an * AttributeValue element of a different type than the one provided * in the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. Also, * {"N":"6"} does not compare to * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * GE : Greater than or equal. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If an item * contains an AttributeValue element of a different type than the * one provided in the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. Also, * {"N":"6"} does not compare to * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * GT : Greater than. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If an item * contains an AttributeValue element of a different type than the * one provided in the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. Also, * {"N":"6"} does not compare to * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * NOT_NULL : The attribute exists. NOT_NULL is * supported for all datatypes, including lists and maps. *

      * *

      * This operator tests for the existence of an attribute, not its data type. * If the data type of attribute "a" is null, and you evaluate * it using NOT_NULL, the result is a Boolean true. This * result is because the attribute "a" exists; its data type is * not relevant to the NOT_NULL comparison operator. *

      *
    • *
    • *

      * NULL : The attribute does not exist. NULL is * supported for all datatypes, including lists and maps. *

      * *

      * This operator tests for the nonexistence of an attribute, not its data * type. If the data type of attribute "a" is null, and you * evaluate it using NULL, the result is a Boolean * false. This is because the attribute "a" exists; its * data type is not relevant to the NULL comparison operator. *

      *
    • *
    • *

      * CONTAINS : Checks for a subsequence, or value in a set. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If the target * attribute of the comparison is of type String, then the operator checks * for a substring match. If the target attribute of the comparison is of * type Binary, then the operator looks for a subsequence of the target that * matches the input. If the target attribute of the comparison is a set (" * SS", "NS", or "BS"), then the * operator evaluates to true if it finds an exact match with any member of * the set. *

      *

      * CONTAINS is supported for lists: When evaluating " * a CONTAINS b", "a" can be a list; however, " * b" cannot be a set, a map, or a list. *

      *
    • *
    • *

      * NOT_CONTAINS : Checks for absence of a subsequence, or * absence of a value in a set. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If the target * attribute of the comparison is a String, then the operator checks for the * absence of a substring match. If the target attribute of the comparison * is Binary, then the operator checks for the absence of a subsequence of * the target that matches the input. If the target attribute of the * comparison is a set ("SS", "NS", or " * BS"), then the operator evaluates to true if it does * not find an exact match with any member of the set. *

      *

      * NOT_CONTAINS is supported for lists: When evaluating " * a NOT CONTAINS b", "a * " can be a list; however, "b" cannot be a set, a map, or a * list. *

      *
    • *
    • *

      * BEGINS_WITH : Checks for a prefix. *

      *

      * AttributeValueList can contain only one AttributeValue of * type String or Binary (not a Number or a set type). The target attribute * of the comparison must be of type String or Binary (not a Number or a set * type). *

      *

    • *
    • *

      * IN : Checks for matching elements within two sets. *

      *

      * AttributeValueList can contain one or more AttributeValue * elements of type String, Number, or Binary (not a set type). These * attributes are compared against an existing set type attribute of an * item. If any elements of the input set are present in the item attribute, * the expression evaluates to true. *

      *
    • *
    • *

      * BETWEEN : Greater than or equal to the first value, and less * than or equal to the second value. *

      *

      * AttributeValueList must contain two AttributeValue elements * of the same type, either String, Number, or Binary (not a set type). A * target attribute matches if the target value is greater than, or equal * to, the first element and less than, or equal to, the second element. If * an item contains an AttributeValue element of a different type * than the one provided in the request, the value does not match. For * example, {"S":"6"} does not compare to * {"N":"6"}. Also, {"N":"6"} does not compare to * {"NS":["6", "2", "1"]} *

    *

*

* For usage examples of AttributeValueList and * ComparisonOperator, see Legacy Conditional Parameters in the Amazon DynamoDB Developer * Guide. *

*

* For backward compatibility with previous DynamoDB releases, the following * parameters can be used instead of AttributeValueList and * ComparisonOperator: *

*
    *
  • *

    * Value - A value for DynamoDB to compare with an attribute. *

    *
  • *
  • *

    * Exists - A Boolean value that causes DynamoDB to evaluate the * value before attempting the conditional operation: *

    *
      *
    • *

      * If Exists is true, DynamoDB will check to see if that * attribute value already exists in the table. If it is found, then the * condition evaluates to true; otherwise the condition evaluate to false. *

      *
    • *
    • *

      * If Exists is false, DynamoDB assumes that the * attribute value does not exist in the table. If in fact the value * does not exist, then the assumption is valid and the condition evaluates * to true. If the value is found, despite the assumption that it does not * exist, the condition evaluates to false. *

      *
    • *
    *

    * Note that the default value for Exists is true. *

    *
  • *
*

* The Value and Exists parameters are incompatible with * AttributeValueList and ComparisonOperator. Note that if you * use both sets of parameters at once, DynamoDB will return a * ValidationException exception. *

      *

    • *
    • *

      * NOT_NULL : The attribute exists. NOT_NULL is * supported for all datatypes, including lists and maps. *

      * *

      * This operator tests for the existence of an attribute, not its data type. * If the data type of attribute "a" is null, and you evaluate * it using NOT_NULL, the result is a Boolean true. This * result is because the attribute "a" exists; its data type is * not relevant to the NOT_NULL comparison operator. *

      *
    • *
    • *

      * NULL : The attribute does not exist. NULL is * supported for all datatypes, including lists and maps. *

      * *

      * This operator tests for the nonexistence of an attribute, not its data * type. If the data type of attribute "a" is null, and you * evaluate it using NULL, the result is a Boolean * false. This is because the attribute "a" exists; its * data type is not relevant to the NULL comparison operator. *

      *
    • *

      * CONTAINS : Checks for a subsequence, or value in a set. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If the target * attribute of the comparison is of type String, then the operator checks * for a substring match. If the target attribute of the comparison is of * type Binary, then the operator looks for a subsequence of the target that * matches the input. If the target attribute of the comparison is a set (" * SS", "NS", or "BS"), then the * operator evaluates to true if it finds an exact match with any member of * the set. *

      *

      * CONTAINS is supported for lists: When evaluating " * a CONTAINS b", "a" can be a list; however, " * b" cannot be a set, a map, or a list. *

      *
    • *
    • *

      * NOT_CONTAINS : Checks for absence of a subsequence, or * absence of a value in a set. *

      *

      * AttributeValueList can contain only one AttributeValue * element of type String, Number, or Binary (not a set type). If the target * attribute of the comparison is a String, then the operator checks for the * absence of a substring match. If the target attribute of the comparison * is Binary, then the operator checks for the absence of a subsequence of * the target that matches the input. If the target attribute of the * comparison is a set ("SS", "NS", or " * BS"), then the operator evaluates to true if it does * not find an exact match with any member of the set. *

      *

      * NOT_CONTAINS is supported for lists: When evaluating " * a NOT CONTAINS b", "a * " can be a list; however, "b" cannot be a set, a map, or a * list. *

      *
    • *
    • *

      * BEGINS_WITH : Checks for a prefix. *

      *

      *

    • *
    • *

      * IN : Checks for matching elements within two sets. *

      *

      * AttributeValueList can contain one or more AttributeValue * elements of type String, Number, or Binary (not a set type). These * attributes are compared against an existing set type attribute of an * item. If any elements of the input set are present in the item attribute, * the expression evaluates to true. *

      *
    • *
    • *

      * BETWEEN : Greater than or equal to the first value, and less * than or equal to the second value. *

      *

      * AttributeValueList must contain two AttributeValue elements * of the same type, either String, Number, or Binary (not a set type). A * target attribute matches if the target value is greater than, or equal * to, the first element and less than, or equal to, the second element. If * an item contains an AttributeValue element of a different type * than the one provided in the request, the value does not match. For * example, {"S":"6"} does not compare to * {"N":"6"}.

* For usage examples of AttributeValueList and * ComparisonOperator, see Legacy Conditional Parameters in the Amazon DynamoDB Developer * Guide. *

*

* For backward compatibility with previous DynamoDB releases, the following * parameters can be used instead of AttributeValueList and * ComparisonOperator: *

*
    *
  • *

    * Value - A value for DynamoDB to compare with an attribute. *

    *
  • *
  • *

    * Exists - A Boolean value that causes DynamoDB to evaluate the * value before attempting the conditional operation: *

    *
      *
    • *

      * If Exists is true, DynamoDB will check to see if that * attribute value already exists in the table. If it is found, then the * condition evaluates to true; otherwise the condition evaluate to false. *

      *
    • *
    • *

      * If Exists is false, DynamoDB assumes that the * attribute value does not exist in the table. If in fact the value * does not exist, then the assumption is valid and the condition evaluates * to true. If the value is found, despite the assumption that it does not * exist, the condition evaluates to false. *

      *
    • *
    *

    * Note that the default value for Exists is true. *

    *
  • *
*

* The Value and Exists parameters are incompatible with * AttributeValueList and ComparisonOperator. Note that if you * use both sets of parameters at once, DynamoDB will return a * ValidationException exception. *

*

* For usage examples of AttributeValueList and * ComparisonOperator, see Legacy Conditional Parameters in the Amazon DynamoDB Developer * Guide. *

*

* For backward compatibility with previous DynamoDB releases, the following * parameters can be used instead of AttributeValueList and * ComparisonOperator: *

*
    *
  • *

    * Value - A value for DynamoDB to compare with an attribute. *

    *
  • *
  • *

    * Exists - A Boolean value that causes DynamoDB to evaluate the * value before attempting the conditional operation: *

    *
      *
    • *

      * If Exists is true, DynamoDB will check to see if that * attribute value already exists in the table. If it is found, then the * condition evaluates to true; otherwise the condition evaluate to false. *

      *
    • *
    • *

      * If Exists is false, DynamoDB assumes that the * attribute value does not exist in the table. If in fact the value * does not exist, then the assumption is valid and the condition evaluates * to true. If the value is found, despite the assumption that it does not * exist, the condition evaluates to false. *

      *
    • *
    *

    * Note that the default value for Exists is true. *

    *
  • *
*

* The Value and Exists parameters are incompatible with * AttributeValueList and ComparisonOperator. Note that if you * use both sets of parameters at once, DynamoDB will return a * ValidationException exception. *

* * @param expected *

* This is a legacy parameter, for backward compatibility. New * applications should use ConditionExpression instead. Do not * combine legacy parameters and expression parameters in a single * API call; otherwise, DynamoDB will return a * ValidationException exception. *

* *

* A map of attribute/condition pairs. Expected provides a * conditional block for the PutItem operation. *

* *

* This parameter does not support attributes of type List or Map. *

*
*

* Each element of Expected consists of an attribute name, a * comparison operator, and one or more values. DynamoDB compares the * attribute with the value(s) you supplied, using the comparison * operator. For each Expected element, the result of the * evaluation is either true or false. *

*

* If you specify more than one element in the Expected map, * then by default all of the conditions must evaluate to true. In * other words, the conditions are ANDed together. (You can use the * ConditionalOperator parameter to OR the conditions instead. * If you do this, then at least one of the conditions must evaluate * to true, rather than all of them.) *

*

* If the Expected map evaluates to true, then the conditional * operation succeeds; otherwise, it fails. *

*

* Expected contains the following: *

*
    *
  • *

    * AttributeValueList - One or more values to evaluate against * the supplied attribute. The number of values in the list depends * on the ComparisonOperator being used. *

    *

    * For type Number, value comparisons are numeric. *

    *

    * String value comparisons for greater than, equals, or less than * are based on ASCII character code values. For example, * a is greater than A, and a * is greater than B. For a list of code values, see http * ://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters. *

    *

    * For type Binary, DynamoDB treats each byte of the binary data as * unsigned when it compares binary values. *

    *
  • *
  • *

    * ComparisonOperator - A comparator for evaluating attributes * in the AttributeValueList. When performing the comparison, * DynamoDB uses strongly consistent reads. *

    *

    * The following comparison operators are available: *

    *

    * EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN *

    *

    * The following are descriptions of each comparison operator. *

If in fact the value * does not exist, then the assumption is valid and the condition evaluates * to true. If the value is found, despite the assumption that it does not * exist, the condition evaluates to false. *

      *
    • *
    *

    * Note that the default value for Exists is true. *

    *
  • *
*

* The Value and Exists parameters are incompatible with * AttributeValueList and ComparisonOperator. Note that if you * use both sets of parameters at once, DynamoDB will return a * ValidationException exception. *

* * @param expected *

* This is a legacy parameter, for backward compatibility. New * applications should use ConditionExpression instead. Do not * combine legacy parameters and expression parameters in a single * API call; otherwise, DynamoDB will return a * ValidationException exception. *

* *

* A map of attribute/condition pairs. Expected provides a * conditional block for the PutItem operation. *

* *

* This parameter does not support attributes of type List or Map. *

*
*

* Each element of Expected consists of an attribute name, a * comparison operator, and one or more values. DynamoDB compares the * attribute with the value(s) you supplied, using the comparison * operator. For each Expected element, the result of the * evaluation is either true or false. *

*

* If you specify more than one element in the Expected map, * then by default all of the conditions must evaluate to true. In * other words, the conditions are ANDed together. (You can use the * ConditionalOperator parameter to OR the conditions instead. * If you do this, then at least one of the conditions must evaluate * to true, rather than all of them.) *

*

* If the Expected map evaluates to true, then the conditional * operation succeeds; otherwise, it fails. *

*

* Expected contains the following: *

*
    *
  • *

    * AttributeValueList - One or more values to evaluate against * the supplied attribute. The number of values in the list depends * on the ComparisonOperator being used. *

    *

    * For type Number, value comparisons are numeric. *

    *

    * String value comparisons for greater than, equals, or less than * are based on ASCII character code values. For example, * a is greater than A, and a * is greater than B. For a list of code values, see http * ://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters. *

    *

    * For type Binary, DynamoDB treats each byte of the binary data as * unsigned when it compares binary values. *

    *
  • *
  • *

    * ComparisonOperator - A comparator for evaluating attributes * in the AttributeValueList. When performing the comparison, * DynamoDB uses strongly consistent reads. *

    *

    * The following comparison operators are available: *

    *

    * EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN *

    *

    * The following are descriptions of each comparison operator. *

    *
      *
    • *

      * EQ : Equal. EQ is supported for all * datatypes, including lists and maps. *

      *

      * AttributeValueList can contain only one * AttributeValue element of type String, Number, Binary, * String Set, Number Set, or Binary Set. If an item contains an * AttributeValue element of a different type than the one * provided in the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. * Also, {"N":"6"} does not equal * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * NE : Not equal. NE is supported for all * datatypes, including lists and maps. *

      *

      * AttributeValueList can contain only one * AttributeValue of type String, Number, Binary, String Set, * Number Set, or Binary Set. If an item contains an * AttributeValue of a different type than the one provided in * the request, the value does not match. For example, * {"S":"6"} does not equal {"N":"6"}. * Also, {"N":"6"} does not equal * {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * LE : Less than or equal. *

      *

      * AttributeValueList can contain only one * AttributeValue element of type String, Number, or Binary * (not a set type). If an item contains an AttributeValue * element of a different type than the one provided in the request, * the value does not match. For example, {"S":"6"} does * not equal {"N":"6"}. Also, {"N":"6"} * does not compare to {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * LT : Less than. *

      *

      * AttributeValueList can contain only one * AttributeValue of type String, Number, or Binary (not a set * type). If an item contains an AttributeValue element of a * different type than the one provided in the request, the value * does not match. For example, {"S":"6"} does not equal * {"N":"6"}. Also, {"N":"6"} does not * compare to {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * GE : Greater than or equal. *

      *

      * AttributeValueList can contain only one * AttributeValue element of type String, Number, or Binary * (not a set type). If an item contains an AttributeValue * element of a different type than the one provided in the request, * the value does not match. For example, {"S":"6"} does * not equal {"N":"6"}. Also, {"N":"6"} * does not compare to {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * GT : Greater than. *

      *

      * AttributeValueList can contain only one * AttributeValue element of type String, Number, or Binary * (not a set type). If an item contains an AttributeValue * element of a different type than the one provided in the request, * the value does not match. For example, {"S":"6"} does * not equal {"N":"6"}. Also, {"N":"6"} * does not compare to {"NS":["6", "2", "1"]}. *

      *

    • *
    • *

      * NOT_NULL : The attribute exists. * NOT_NULL is supported for all datatypes, including * lists and maps. *

      * *

      * This operator tests for the existence of an attribute, not its * data type. If the data type of attribute "a" is null, * and you evaluate it using NOT_NULL, the result is a * Boolean true. This result is because the attribute " * a" exists; its data type is not relevant to the * NOT_NULL comparison operator. *

      *
    • *
    • *

      * NULL : The attribute does not exist. * NULL is supported for all datatypes, including lists * and maps. *

      * *

      * This operator tests for the nonexistence of an attribute, not its * data type. If the data type of attribute "a" is null, * and you evaluate it using NULL, the result is a * Boolean false. This is because the attribute " * a" exists; its data type is not relevant to the * NULL comparison operator. *

      *
    • *
    • *

      * CONTAINS : Checks for a subsequence, or value in a * set. *

      *

      * AttributeValueList can contain only one * AttributeValue element of type String, Number, or Binary * (not a set type). If the target attribute of the comparison is of * type String, then the operator checks for a substring match. If * the target attribute of the comparison is of type Binary, then the * operator looks for a subsequence of the target that matches the * input. If the target attribute of the comparison is a set (" * SS", "NS", or "BS"), then * the operator evaluates to true if it finds an exact match with any * member of the set. *

      *

      * CONTAINS is supported for lists: When evaluating " * a CONTAINS b", "a * " can be a list; however, "b" cannot be a set, a map, * or a list. *

      *
    • *
    • *

      * NOT_CONTAINS : Checks for absence of a subsequence, * or absence of a value in a set. *

      *

      * AttributeValueList can contain only one * AttributeValue element of type String, Number, or Binary * (not a set type). If the target attribute of the comparison is a * String, then the operator checks for the absence of a substring * match. If the target attribute of the comparison is Binary, then * the operator checks for the absence of a subsequence of the target * that matches the input. If the target attribute of the comparison * is a set ("SS", "NS", or " * BS"), then the operator evaluates to true if it * does not find an exact match with any member of the set. *

      *

      * NOT_CONTAINS is supported for lists: When evaluating " * a NOT CONTAINS b", "a * " can be a list; however, "b" cannot be a set, a map, * or a list. *

      *
    • *
    • *

      * BEGINS_WITH : Checks for a prefix. *

      *

      * AttributeValueList can contain only one * AttributeValue of type String or Binary (not a Number or a * set type). The target attribute of the comparison must be of type * String or Binary (not a Number or a set type). *

      *

    • *
    • *

      * IN : Checks for matching elements within two sets. *

      *

      * AttributeValueList can contain one or more * AttributeValue elements of type String, Number, or Binary * (not a set type). These attributes are compared against an * existing set type attribute of an item. If any elements of the * input set are present in the item attribute, the expression * evaluates to true. *

      *
    • *
    • *

      * BETWEEN : Greater than or equal to the first value, * and less than or equal to the second value. *

      *

      * AttributeValueList must contain two AttributeValue * elements of the same type, either String, Number, or Binary (not a * set type). A target attribute matches if the target value is * greater than, or equal to, the first element and less than, or * equal to, the second element. If an item contains an * AttributeValue element of a different type than the one * provided in the request, the value does not match. For example, * {"S":"6"} does not compare to {"N":"6"}. * Also, {"N":"6"} does not compare to * {"NS":["6", "2", "1"]} *

      *
    • *
    *
  • *
*

* For usage examples of AttributeValueList and * ComparisonOperator, see Legacy Conditional Parameters in the Amazon DynamoDB * Developer Guide. *

*

* For backward compatibility with previous DynamoDB releases, the * following parameters can be used instead of * AttributeValueList and ComparisonOperator: *

*
    *
  • *

    * Value - A value for DynamoDB to compare with an attribute. *

    *
  • *
  • *

    * Exists - A Boolean value that causes DynamoDB to evaluate * the value before attempting the conditional operation: *

    *
      *
    • *

      * If Exists is true, DynamoDB will check to see * if that attribute value already exists in the table. If it is * found, then the condition evaluates to true; otherwise the * condition evaluate to false. *

      *
    • *
    • *

      * If Exists is false, DynamoDB assumes that the * attribute value does not exist in the table. If in fact the * value does not exist, then the assumption is valid and the * condition evaluates to true. If the value is found, despite the * assumption that it does not exist, the condition evaluates to * false. *

      *
    • *
    *

    * Note that the default value for Exists is true * . *

    *
  • *
*

* The Value and Exists parameters are incompatible * with AttributeValueList and ComparisonOperator. Note * that if you use both sets of parameters at once, DynamoDB will * return a ValidationException exception. * @return Returns a reference to this object so that method calls can be * chained together. */ public PutItemRequest withExpected( java.util.Map expected) { setExpected(expected); return this; } public PutItemRequest addExpectedEntry(String key, ExpectedAttributeValue value) { if (null == this.expected) { this.expected = new java.util.HashMap(); } if (this.expected.containsKey(key)) throw new IllegalArgumentException("Duplicated keys (" + key.toString() + ") are provided."); this.expected.put(key, value); return this; } /** * Removes all the entries added into Expected. <p> Returns a reference * to this object so that method calls can be chained together. */ public PutItemRequest clearExpectedEntries() { this.expected = null; return this; } /** *
