This is the base class for AnimChannel and AnimBundle.
It implements a hierarchy of AnimChannels. The root of the hierarchy must be an AnimBundle.
Definition at line 36 of file animGroup.h.
AnimGroup::AnimGroup | ( | AnimGroup * | parent, |
const string & | name | ||
) |
Creates the AnimGroup, and adds it to the indicated parent.
The only way to delete it subsequently is to delete the entire hierarchy.
Definition at line 78 of file animGroup.cxx.
