Class UndoManager

java.lang.Object

org.gjt.sp.jedit.buffer.UndoManager

public class UndoManager
extends Object

A class internal to jEdit's document model. You should not use it directly. To improve performance, none of the methods in this class check for out of bounds access, nor are they thread-safe. The Buffer class, through which these methods must be called through, implements such protection.
