/**
* A simpler, and more user-friendly version of the generated {@link AttributeValue}.
*
*
* This is a union type of the types exposed by DynamoDB, exactly as they're exposed by DynamoDB.
*
*
* An instance of {@link EnhancedAttributeValue} represents exactly one DynamoDB type, like String (s), Number (n) or Bytes (b).
* This type can be determined with the {@link #type()} method or the {@code is*} methods like {@link #isString()} or
* {@link #isNumber()}. Once the type is known, the value can be extracted with {@code as*} methods like {@link #asString()}
* or {@link #asNumber()}.
*
*
* When converting an {@link EnhancedAttributeValue} into a concrete Java type, it can be tedious to use the {@link #type()} or
* {@code is*} methods. For this reason, a {@link #convert(TypeConvertingVisitor)} method is provided that exposes a polymorphic
* way of converting a value into another type.
*
*
* An instance of {@link EnhancedAttributeValue} is created with the {@code from*} methods, like {@link #fromString(String)} or
* {@link #fromNumber(String)}.
