public KeyGenerator getKeyGenerator(PersistenceFactory factory,
                                    Properties params,
                                    int sqlType)

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.
