      • 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
