All Implemented Interfaces:

public abstract class LazyNavigator

extends Navigator

The LazyNavigator class extends the Navigator class and makes it easy to delay time-consuming navigator initializations. By implementing addView(View), removeView(View), and initNavigator(View[]), the LazyNavigator postpones the actual initialization of the Navigator until the doInitializationNow() method is called. The LazyNavigator class introduces the following protected abstract methods:

• protected abstract void doInitializationNow()
• protected abstract void addViewNow(View view)
• protected abstract void removeViewNow(View view)

Subclasses of LazyNavigator must implement the above methods as well as the getCurrentSelection() and getDefaultLabel() from the Navigator superclass.
