oldObj - the object present in the EditingContext, is null if no object is present

Returns:

the Swizzled Object

isSameInstance

public boolean isSameInstance(Object swizzledObject,
                              Object object)

Description copied from interface: Swizzling

Returns:

true, if they are the same. false, otherwise.
