org.eclipse.persistence.internal.identitymaps.IdentityMap

Purpose: Provides the interface for IdentityMap interaction.
Responsibilities: Provides access to all of the public interface for the EclipseLink IdentityMaps. This interface can be used if implementing custom identity maps that are radically different than the stock IdentityMaps otherwise simply extending the appropriate IdentityMap implementation is the best approach. @see CacheKey @since EclipseLink 1.0M7
