java.lang.Object
   org.hibernate.id.AbstractPostInsertGenerator
      org.hibernate.id.IdentityGenerator

All Implemented Interfaces:
PostInsertIdentifierGenerator

A generator for use with ANSI-SQL IDENTITY columns used as the primary key. The IdentityGenerator for autoincrement/identity key generation.

Indicates to the Session that identity (ie. identity/autoincrement column) key generation should be used.

Nested Class Summary:
public static class	IdentityGenerator.GetGeneratedKeysDelegate	Delegate for dealing with IDENTITY columns using JDBC3 getGeneratedKeys
public static class	IdentityGenerator.InsertSelectDelegate	Delegate for dealing with IDENTITY columns where the dialect supports returning the generated IDENTITY value directly from the insert statement.
public static class	IdentityGenerator.BasicDelegate	Delegate for dealing with IDENTITY columns where the dialect requires an additional command execution to retrieve the generated IDENTITY value
