00024 //       Class : PartBundleHandle
00025 // Description : This is a trivial class returned by
00026 //               PartBundleNode::get_bundle().  Its purpose is to hold
00027 //               the actual PartBundle pointer contained within the
00028 //               PartBundleNode, so that scene graph flatten
00029 //               operations can safely combine or duplicate
00030 //               PartBundles as necessary without affecting high-level
00031 //               bundle operations.
00032 //
00033 //               The high-level Actor class defined in
00034 //               direct/src/actor, for instance, will store a list of
00035 //               PartBundleHandles instead of on actual PartBundles,
00036 //               so that it will be immune to changes from these
00037 //               flatten operations.
