org.gjt.sp.jedit.gui
Class InputHandler  

java.lang.Object
  org.gjt.sp.jedit.gui.InputHandler

Direct Known Subclasses:

DefaultInputHandler

---

public abstract class InputHandler

extends java.lang.Object

An input handler converts the user's key strokes into concrete actions. It also takes care of macro recording and action repetition.

This class provides all the necessary support code for an input handler, but doesn't actually do any key binding logic. It is up to the implementations of this class to do so.
