Class SequenceKeyGeneratorFactory

Implemented Interfaces:
KeyGeneratorFactory

public final class SequenceKeyGeneratorFactory
extends java.lang.Object
implements KeyGeneratorFactory

SEQUENCE key generator factory. The short name of this key generator is "SEQUENCE". It uses Oracle/PostrgeSQL SEQUENCEs There are two optional parameters for this key generator: 1) name is "sequence" and the default value is "{0}_seq"; 2) name is "returning", values: "true"/"false", default is "false". The latter parameter should be used only with Oracle8i, "true" value turns on more efficient RETURNING syntax. It is possible to use naming patterns like this for obtaining SEQUENCE name by table name. This gives the possibility to use one global key generator declaration rather than one per table.
