Method Detail

generate

public java.lang.Object generate()

Description copied from interface: KeyGenerator

Generates a new unique key. If this method is called twice it will never return the same key twice (if key A is returned by first call and key B by second call, A does not equals B). A order of returned keys is not guaranteed (depends on implementation). After a call of the KeyGenerator.reset() method the generator is reseted so that a key can be returned which already was returned before calling KeyGenerator.reset().

Specified by:

generate in interface KeyGenerator

Returns:

unique key

generateFor

public java.lang.Object generateFor(java.lang.Object object)

Generates a PK for a given typecode as Integer.

Specified by:

Parameters:

object - object for which a key will be generated

Returns:

unique key in relation to given object

reset

public void reset()

Description copied from interface: KeyGenerator

Resets the key generation so that an already generated key can be generated once again.
