Class IdentityGenerator

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

All Implemented Interfaces:
  BulkInsertionCapableIdentifierGenerator, IdentifierGenerator, PostInsertIdentifierGenerator

    public class IdentityGenerator

extends AbstractPostInsertGenerator

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