The Stormpath Java SDK API .jar provides a Java API that your code can use to make calls to the Stormpath API. This .jar is the only compile-time dependency within the Stormpath SDK project that your code should depend on. Implementations of this API (implementation .jars) should be runtime dependencies only.

There is a newer version: 2.0.4-okta

/**
 * A rule that indicates how a SAML Attribute Statement should populate one or more Stormpath Account field values.  By
 * creating rules, you configure which SAML Attribute values should be copied to Stormpath Account field values.
 * {@code AttributeStatementMappingRule}s are immutable.  If you want to change the mapping rules for Accounts in a
 * particular SAML Directory, you must remove and add new {@code AttributeStatementMappingRule} instances to the
 * Directory Provider's {@link AttributeStatementMappingRules} instance.
 *
 * 
How does it work?
 * Each {@code AttributeStatementMappingRule} has a {@code name} and a collection of Stormpath account
 * {@link #getAccountAttributes() attribute names}.
 * When a SAML Attribute Statement is encountered, every SAML Attribute with a matching name will have its value
 * copied to the corresponding specified Stormpath account fields.
 *
 * Example
 * For example, assume that a mapping rule's {@code name} is {@code foo}, and the rule's
 * {@link #getAccountAttributes() accountAttributes} collection contains the Stormpath Account field names
 * of {@code givenName} and {@code surname}.
 * If an Attribute Statement named {@code foo} is encountered on login to have a value of {@code bar}, then
 * {@code bar} will automatically be copied to the specified Stormpath Account fields for that user.  This user would
 * then automatically have a {@code givenName} of {@code bar} and a {@code surname} of {@code bar}.
 *
