public interface ObjectCopier
Provides an interface for a variety of means to copy an arbitrary object. Any
implementation of this interface must return an exact copy of obj, preserving
all aliasing across all objects reachable from obj. ReflectiveCopyException
must be thrown if the implementation cannot copy obj for some reason. Note
that a trivial implementation of this interface is possible (always return
obj), but this is often not the desired implementation.
