Composite Commnads

Composite Commands provide a way to combine commands into one unit. A composite command is executed and undone as if it is a single command.

Example Usage

Example taken from Zoom.java which is a tool see Tools:

NavigationCommandFactory factory = NavigationCommandFactory.getInstance();

NavCommand[] commands = new NavCommand[] {
   factory.createSetViewportCenterCommand(m.pixelToWorld( r.x + r.width / 2, r.y + r.height / 2)),
   factory.createZoomCommand(r.width / getContext().getMapDisplay().getDisplaySize().getWidth()) };

   map.sendCommand(factory.createCompositeCommand(commands));
