java.lang.Object
com.luciad.gui.TLcdUndoHistory
public class TLcdUndoHistory extends Object
Deprecated.
This class has no more use. Please use the new mechanism based on ILcdUndoable and TLcdUndoManager.
This is an utility class to help making an ILcdUndoable that can perform undo/redo operations. It keeps a list of Objects that represents a sequence of actions done by an ILcdUndoable. Each Object is supposed to contains the information the ILcdUndoable needs to keep in order to perform an undo or redo. The call of undo(ILcdFunction), respectively redo(ILcdFunction), will retrieve the corresponding Object and apply on it the given ILcdFunction. This ILcdFunction has to be given by the ILcdUndobale and shall effectively performs the undo, respectively redo, action. This class keep track of the number of undo and redo left.
