Revision 1799 - (show annotations)
Wed Sep 17 06:33:18 2008 UTC (11 years ago) by jfenwick
File size: 13419 byte(s)
Added Data::copySelf() [Note: this is exposed as copy() in python].
This method returns a pointer to a deep copy of the target.
There are c++ tests but no python tests for this yet.

All DataAbstracts now have a deepCopy() which simplifies the 
implementation of the compy methods.
