Method Detail
-
getKeyGeneratorName
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.- Returns:
- Name of the
KeyGenerator
used to identify key generator (types).

getKeyGenerator
KeyGenerator getKeyGenerator(PersistenceFactory factory, java.util.Properties params, int sqlType) throws MappingException
Produce the key generator.- 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.
