public abstract class AbstractApplication
extends java.lang.Object
implements Application

An abstract implementation of the Application interface. This class implements the common elements of the Application abstraction, and takes care of listener notification for documents and properties. Concrete subclasses will generally override a number of these methods to add their own behavior. Most importantly, this abstract class does not provide any support for creating documents, or managing the views of those documents. For an example of one way of managing the view associated with a document, see MDIApplication.
