00032 // Purpose: This file contains the class definition for DummyNode.
00033 // DummyNodes are a type of node created and used by Subdomains for their
00034 // exterior nodes. They reference a real node and most methods invoked on
00035 // them are in turn invoked by the dummy node on the real node. The calls
00036 // asking the real node to change its current state are ignored. The
00037 // calls involving DOF\_Group are handled by the dummy node. \\
00038 //
00039 // 
00040 // What: "@(#) DummyNode.h, revA"
