  org.eclipse.core.commands.common.EventManager
      org.eclipse.jface.viewers.BaseLabelProvider

All Implemented Interfaces:

org.eclipse.jface.viewers.IBaseLabelProvider, org.eclipse.jface.viewers.IContentProvider, org.eclipse.jface.viewers.ILabelProvider, org.eclipse.jface.viewers.IStructuredContentProvider, org.eclipse.ui.navigator.IDescriptionProvider

public abstract class DelegatingContentAndLabelProvider
extends org.eclipse.jface.viewers.BaseLabelProvider
implements org.eclipse.jface.viewers.IStructuredContentProvider, org.eclipse.jface.viewers.ILabelProvider, org.eclipse.ui.navigator.IDescriptionProvider

Implementation of IStructuredContentProvider and ILabelProvider that maintains a collection (Map, actually) of ItemContentProvider delegates that perform the function of providing content and label information for each represented item NB: This class, if used as a label provider *MUST* be used as a content provider for the same viewer. It may be used as a content provider with a different label provider, however. Provisional API: This class is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
