public NoKeyGeneratorFactory()

Method Detail

getKeyGeneratorName

public java.lang.String getKeyGeneratorName()

Get the short name of the key generator. It is used to reference key generators in a mapping configuration file. If several key generators of the same type are used for the same database, then they are referenced by aliases.

Specified by:

getKeyGeneratorName in interface KeyGeneratorFactory

Returns:

Name of the KeyGenerator used to identify key generator (types).

getKeyGenerator

public KeyGenerator getKeyGenerator(PersistenceFactory factory,
                                    java.util.Properties params,
                                    int sqlType)
                             throws MappingException

Produce the key generator.

Specified by:

getKeyGenerator in interface KeyGeneratorFactory

Parameters:

factory - Helper object for obtaining database-specific QuerySyntax.

params - Parameters for key generator.

sqlType - The SQL type of the primary key, the generated identities must have the corresponding Java type, e.g. java.sql.Types.INTEGER corresponds to java.lang.Integer, java.sql.Types.NUMERIC corresponds to java.lang.BigDecimal.

Returns:

A KeyGenerator instance.

Throws:

MappingException - If there's a problem resolving the mapping information.
