Nframe and Frame in the source code #21

What are the differences between class "NFrame" and "Frame" in the source code? I have noticed that the "NFrame" contains a member variable called "frames_" with type "FrameVector", so an object of "NFrame" contains not only 1 frame, right? But at the same time, "NFrame" contains another variable called "is_keyframe_" with type bool, which seems imply that it is indeed a single frame? Thanks in advance!
FrameVector frames_; //!< Vector of frames holding images and features. bool is_keyframe_ = false; //!< Was this NFrame selected as keyframe?
