Examples of org.eclipse.ui.IEditorActionBarContributor

org.eclipse.ui.IEditorActionBarContributor
A editor action bar contributor defines the actions for one or more editors.
Within the workbench there may be more than one open editor of a particular type. For instance, there may be 1 or more open Java Editors. To avoid the creation of duplicate actions and action images the editor concept has been split into two. An action contributor is responsable for the creation of actions. The editor is responsible for action implementation. Furthermore, the contributor is shared by each open editor. As a result of this design there is only 1 set of actions for 1 or more open editors.
The relationship between editor and contributor is defined by the org.eclipse.ui.editors extension point in the plugin registry. For each extension an editor class and a contributor class must be defined.
This interface should not be implemented directly. An implementation of this interface has been created in EditorActionBarContributor. Implementors should subclass this and specialize as required.
