25/**
26 * A interface for notification of buffer undo/redo actions.
27 *
28 * This interface makes it easier for undo-aware plugins to process
29 * undo/redo actions in a buffer.
30 *
31 * Buffer undo listeners are added and removed from a buffer using
32 * <code>JEditBuffer.addBufferUndoListener<code> and
33 * <code>JEditBuffer.removeBufferUndoListener<code>, respectively.
