Class ConnectionViewFactory

java.lang.Object
  org.eclipse.gmf.runtime.diagram.ui.view.factories.AbstractViewFactory
      org.eclipse.gmf.runtime.diagram.ui.view.factories.ConnectionViewFactory

All Implemented Interfaces:

ViewFactory

public class ConnectionViewFactory

extends AbstractViewFactory

implements ViewFactory

This is the bas factory class for all connection views, it will create the view and decorate it using the default decorations you can subclass it to add more decorations, or customize the way it looks, like adding new style

See Also:

#createView(IAdaptable, View, String, int, boolean, String), ConnectionViewFactory.decorateView(View, View, IAdaptable, String, int, boolean), #createStyles()

Constructor Summary

ConnectionViewFactory()

Method Summary

protected Bendpoints	createBendpoints() this method will create the default bend point on the connection, connections are created as Straight linem you can override this method in your own factory that subclass this class and change this behavior by adding extra bend points or returning a new list of bend points.
protected java.util.List	createStyles(View view) this method is called by @link #createView(IAdaptable, View, String, int, boolean) to create the styles for the view that will be created, you can override this method in you factory sub class to provide additional styles
View	createView(IAdaptable semanticAdapter, View containerView, java.lang.String semanticHint, int index, boolean persisted, PreferencesHint preferencesHint) factory method, that will be called by the view service to creat the view
protected void	decorateView(View containerView, View view, IAdaptable element, java.lang.String semanticHint, int index, boolean persisted) This method is responsible for decorating the created view, it get called by the Factory method @link #createView(IAdaptable, View, String, int, boolean), it will intiliaze the view with the default preferences also it will create the default elements of the View if it had any
protected void	initializeFromPreferences(View view) Initialize the passed view from the preference store
protected static boolean	isUnProtectedSilentTransactionInProgress(org.eclipse.emf.transaction.TransactionalEditingDomain domain) Checks if the current active transaction is a unprotected amd silent

Description copied from interface: ViewFactory

factory method, that will be called by the view service to creat the view

Specified by:

createView in interface ViewFactory

Specified by:

createView in class AbstractViewFactory

createBendpoints

protected Bendpoints createBendpoints()

this method will create the default bend point on the connection, connections are created as Straight linem you can override this method in your own factory that subclass this class and change this behavior by adding extra bend points or returning a new list of bend points. This method get called by @link #createView(IAdaptable, View, String, int, boolean)

Returns:

a list of style for the newly created view or an empty list if none (do not return null)

decorateView

protected void decorateView(View containerView,
                            View view,
                            IAdaptable element,
                            java.lang.String semanticHint,
