clone

public Object clone()

Overrides:

clone in class Object

dispose

public void dispose()

Releases all of the resources used by this object instance and all of its owned children. Its primary use is to allow the garbage collector to perform a vanilla job.

This method should be called only if it is for sure that this object instance will never be used again. The results of referencing an instance of this class after a call to dispose() are undefined.

Overrides of this method should always call super.dispose(); after disposing this instance.

Specified by:

dispose in class ProductData
