public SystemTimeGenerator()

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)

Description copied from interface: KeyGenerator

Generates a new unique key in relation to given object. The key will be unique overall as in KeyGenerator.generate() method and furthermore it is guaranteed that the key will only be produced for this object (think of a PK which contains the type information, a media PK will not be generated for a product, nevertheless it is unique overall).

Specified by:

generateFor in interface KeyGenerator

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.

Specified by:

reset in interface KeyGenerator
