virtual double get_frame_rate() const
Returns the stated frame rate of this particular joint, or 0.0 if it doesn't state.
virtual void extend_to(int num_frames)
Extends the table to the indicated number of frames.
virtual bool has_vertices() const
Returns true if there are any vertices referenced by the node this points to, false otherwise.
virtual void set_name(const std::string &name)
Applies the indicated name change to the egg file.
TypeHandle is the identifier used to differentiate C++ class types.
