tree-buffers: Only for internal use! It contains all
tree-buffers of current Emacs-instance, means all
tree-buffers of all applications which uses currently
tree-buffers. Every application must store its own collection of
tree-buffers in an own variable! For example: ECB stores its
tree-buffer set in
tree-buffer-displayed-nodes: Only for internal use!
Contains all the current visible nodes of current tree-buffer in
top-to-bottom order. This variable is buffer-local in each
tree-buffer! Do not use it directly! When you want to cache the
current display, then see Tree-buffer How to how to do this.
IMPORTANT: An application may only use the API tree-buffer.el provides but no internal variables - see The tree-buffer-API!
