Description

Interface Summary

Configurable An IdentifierGenerator that supports "configuration".

IdentifierGenerator The general contract between a class that generates unique identifiers and the Session.

PersistentIdentifierGenerator An IdentifierGenerator that requires creation of database objects.

PostInsertIdentifierGenerator

PostInsertIdentityPersister A persister that may have an identity assigned by execution of a SQL INSERT.

Class Summary

AbstractPostInsertGenerator

AbstractUUIDGenerator The base class for identifier generators that use a UUID algorithm.

Assigned assigned

An IdentifierGenerator that returns the current identifier assigned to an instance.

ForeignGenerator foreign

An Identifier generator that uses the value of the id property of an associated object

One mapping parameter is required: property.

GUIDGenerator Generates string values using the SQL Server NEWID() function.

IdentifierGeneratorFactory Factory and helper methods for IdentifierGenerator framework.

IdentityGenerator A generator for use with ANSI-SQL IDENTITY columns used as the primary key.

IdentityGenerator.BasicDelegate Delegate for dealing with IDENTITY columns where the dialect requires an additional command execution to retrieve the generated IDENTITY value

IdentityGenerator.GetGeneratedKeysDelegate Delegate for dealing with IDENTITY columns using JDBC3 getGeneratedKeys

IdentityGenerator.InsertSelectDelegate Delegate for dealing with IDENTITY columns where the dialect supports returning the generated IDENTITY value directly from the insert statement.

IncrementGenerator increment

An IdentifierGenerator that returns a long, constructed by counting from the maximum primary key value at startup.

MultipleHiLoPerTableGenerator A hilo IdentifierGenerator that returns a Long, constructed using a hi/lo algorithm.

SelectGenerator A generator that selects the just inserted row to determine the identifier value assigned by the database.

SelectGenerator.SelectGeneratorDelegate The delegate for the select generation strategy.

SequenceGenerator sequence

Generates long values using an oracle-style sequence.

SequenceHiLoGenerator seqhilo

An IdentifierGenerator that combines a hi/lo algorithm with an underlying oracle-style sequence that generates hi values.

SequenceIdentityGenerator A generator which combines sequence generation with immediate retrieval through JDBC3 getGeneratedKeys.

SequenceIdentityGenerator.Delegate

SequenceIdentityGenerator.NoCommentsInsert

TableGenerator An IdentifierGenerator that uses a database table to store the last generated value.

TableHiLoGenerator hilo

An IdentifierGenerator that returns a Long, constructed using a hi/lo algorithm.

UUIDHexGenerator uuid

A UUIDGenerator that returns a string of length 32, This string will consist of only hex digits.

Exception Summary

IdentifierGenerationException Thrown by IdentifierGenerator implementation class when ID generation fails.
