Class Token


  • public class Token
    extends Object
    A simple domain value responsible for modelling a Core Token Service Token. This container is intended to be generic and has little knowledge of the data it is storing. The Token is backed by the CoreTokenField enumeration which contains the known fields that can be written to. Every value being stored must be mapped to one of these CoreTokenFields. There are some read only fields which can only be set during initialisation of the Token. The Token models the data stored in two ways. Firstly the primary fields of the Token are accessible via getters and setters. All other fields are accessed in a more generic way.

      • getAttribute

        Accessor for the CoreTokenField attributes.
        Type Parameters:
        T - The type of the value stored. Note: this is not enforced and the caller is responsible for determining the correct type to request. See CoreTokenFieldTypes for more details.
        Parameters:
        field - The CoreTokenField to request the value for.
        Returns:
        The value assigned which may be null.
      • getMultiAttribute

Note: This is not a machine readable/parsable format. This function is only intended for debugging use only as its conversion logic will not be performant.
        Overrides:
        toString in class Object

        Non null string which describes the Token.
      • toPartialToken

        Returns:
        A PartialToken.
        Since:
        14.0.0
      • getETag

        public Optional<ETag> getETag()
        A read only copy of the backing CTS implementation ETag.

        Requests to the CTSPersistentStore which include the CTSOptions.ETAG_READ_OPTION option should populate this Token with an ETag.

        This concurrency check can then be included in subsequent modify requests to verify that the Token stored in the backing implementation has not been modified by another caller in the mean time.

        Note: The value of this field (getETag()) is not used by the backing CTS implementation, but rather the value passed in using the Options.

        Note: This feature may not be available or not configured in the backing implementation of the CTS.

        Returns:
        An Optional which if present indicates that an ETag was received for this Token from the backing CTS implementation.

        CTSOptions.ETAG_READ_OPTION, CTSOptions.ETAG_ASSERT_OPTION
