Class PictogramElementDelegate

java.lang.Object

org.eclipse.graphiti.ui.internal.parts.PictogramElementDelegate

All Implemented Interfaces:

org.eclipse.core.runtime.IAdaptable, IFeatureProviderHolder, IVisualStateHolder, IPictogramElementDelegate

Direct Known Subclasses:

AnchorContainerDelegate

public class PictogramElementDelegate
extends Object
implements IPictogramElementDelegate

A class, which contains helper-methods, which are necessary to implement the interface IAnchorContainerEditPart. It is not possible to make this an EditPart itself, because of different inheritance-hierarchies used in the sub-classes.
