Constructor Summary

MappedObjectItemProvider(AdapterFactory adapterFactory, EObject mappedObject, Mapping mapping)
This constructs an instance from a factory and a notifier.

Method Summary

void	dispose() This is called to dispose the object.
Collection	getChildren(Object object) This does the same thing as EditingDomain.getChildren, i.e., it imposes a hierarchical relation on a domain's model objects.
Collection	getElements(Object object) This does the same thing as IStructuredContentProvider.getElements.
Object	getImage(Object object) This does the same thing as ILabelProvider.getImage, it fetches the label image specific to this object instance.
EObject	getMappedObject()
Mapping	getMapping()
Object	getParent(Object object) This returns the nestedIn of the Mapping.
IItemPropertyDescriptor	getPropertyDescriptor(Object object, Object propertyId) This returns the property descriptor with the given ID.
List	getPropertyDescriptors(Object object) This does the same thing as IPropertySource.getPropertyDescriptors.
String	getText(Object object) This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance.
