Interface IdentityIF

All Superinterfaces:
Cloneable
All Known Implementing Classes:
AtomicIdentity, Identity, LongIdentity, WrappedIdentity
public interface IdentityIF extends Cloneable
INTERNAL: Interface used to represent data store object identity. The identity has two parts; the type of object and an ordered list of primary key components. Note that an identity instance should always be immutable. Warning: Implementations of this class must all have the same hashCode() behaviour.
