Application

All Known Implementing Classes:

AbstractApplication, ApplicationTutorial, MDIApplication, MDIApplicationTutorial
```
public interface Application
```
Application is an interface that captures the notion of a graphical application. An application is associated with an ApplicationFrame, and contains a set of Documents. All applications will need to create an implementation of this interface.

- Method Detail
  - actions
```
java.util.Iterator actions()
```
    Get an iterator over the names of the actions that are contained by this application.
  - addAction
```
void addAction(javax.swing.Action action)
```
    Add an action to the table of actions. Every action known by the application should be added to this list so it can be retrieved and invoked later. The action name must be unique in this application.
  - addDocument
```
void addDocument(Document d)
```
    Add a document to the application and notify document listeners. Throw an exception if the document is already in the list of documents.
  - addDocumentListener
```
void addDocumentListener(javax.swing.event.ListDataListener listener)
```
    Add a document listener to this application. The document listener is in fact a ListDataListener, which will be notified with intervalAdded() and intervalRemoved() events when documents are added or removed, and with a contentsChanged() event when the current document is changed.
  - addView
```
void addView(View d)
```
    Add a view to the application and notify view listeners. Throw an exception if the view is already in the list of views.
  - addViewListener
```
void addViewListener(javax.swing.event.ListDataListener listener)
```
    Add a view listener to this application. The view listener is in fact a ListDataListener, which will be notified with intervalAdded() and intervalRemoved() events when views are added or removed, and with a contentsChanged() event when the current view is changed.
  - addPropertyChangeListener
```
void addPropertyChangeListener(java.beans.PropertyChangeListener listener)
```
    Add a property change listener to this application. Changes to certain elements of the state of the application require that registered property change listeners be notified of the change.
  - closeDocument
```
boolean closeDocument(Document d)
```
    Try to close the given document, respecting the storage policy. Return whether or not the operation was successful.
  - closeView
```
boolean closeView(View v)
```
    Try to close the given view, respecting the storage policy. Return whether or not the operation was successful.
  - createView
```
View createView(Document d)
```
    Create a view to display the given document. The document should already be added to the application. After calling this method, most callers should set this view to be the current view.
  - documentList
```
java.util.List documentList()
```
    Get an iterator over all documents
  - viewList
```
java.util.List viewList()
```
    Get an iterator over all views
  - getAction
```
javax.swing.Action getAction(java.lang.String name)
```
    Get an action by name.
  - getCurrentView
```
View getCurrentView()
```
    Get the current view. Generally, this will be the one that is displayed in the window that is top-most in the display. Return null if there is no current document.
  - getClipboard
```
java.awt.datatransfer.Clipboard getClipboard()
```
    Return the clipboard used by this application.
  - getDocumentFactory
```
DocumentFactory getDocumentFactory()
```
    Get the factory that this application uses to create document objects.
  - getAppContext
```
AppContext getAppContext()
```
    Get the context that this application draws itself in. Some applications may have more one than one frame, in which case they probably want to designate one as the "main frame" (heh heh).
  - getStoragePolicy
```
StoragePolicy getStoragePolicy()
```
    Get the storage policy of this application.
  - getTitle
```
java.lang.String getTitle()
```
    Get the title of this application
  - isVisible
```
boolean isVisible()
```
    Test whether the application frame is visible. Return false if the application has no frame or if the frame is not visible.
  - removeDocument
```
void removeDocument(Document d)
```
    This method should only be called by storage policies. It removes a document from the list of documents currently known by this application, and remove all of the views associated with this document. Fire a list data event to registered document listeners. Throw an exception if the document is not known.
  - removeView
```
void removeView(View v)
```
    This method should only be called by storage policies. It removes a view from the list of views currently known by this application. Fire a list data event to registered view listeners. If the removed view is the current view it is up to the application to decide which view to display next. Throw an exception if the view is not known.
  - removeDocumentListener
```
void removeDocumentListener(javax.swing.event.ListDataListener listener)
```
    Remove a document list listener from this application.
  - removeViewListener
```
void removeViewListener(javax.swing.event.ListDataListener listener)
```
    Remove a view list listener from this application.
  - removePropertyChangeListener
```
void removePropertyChangeListener(java.beans.PropertyChangeListener listener)
```
    Remove a property change listener from this application.
  - setCurrentView
```
void setCurrentView(View v)
```
    Set the given view to be the current view. Fire a contentsChanged() event to registered view listeners. Throw an exception of the view is not known.
  - setVisible
```
void setVisible(boolean visible)
```
    Set the visibility of the application's frame
  - showError
```
void showError(java.lang.String op,
               java.lang.Exception e)
```
    Report that an exception occurred to the user.
