org.hibernate.id.insert.AbstractSelectingDelegate

All Implemented Interfaces:

GeneratedValuesMutationDelegate, InsertGeneratedIdentifierDelegate

Direct Known Subclasses:

BasicSelectingDelegate, UniqueKeySelectingDelegate

public abstract class AbstractSelectingDelegate
extends AbstractGeneratedValuesMutationDelegate
implements InsertGeneratedIdentifierDelegate

Abstract GeneratedValuesMutationDelegate implementation where the underlying strategy requires a subsequent select after the insert to determine the generated identifier.
