org.eclipse.ui.IEditorPart
An editor is a visual component within a workbench page. It is typically used to edit or browse a document or input object. The input is identified using an IEditorInput. Modifications made in an editor part follow an open-save-close lifecycle model (in contrast to a view part, where modifications are saved to the workbench immediately).
An editor is document or input-centric. Each editor has an input, and only one editor can exist for each editor input within a page. This policy has been designed to simplify part management.
An editor should be used in place of a view whenever more than one instance of a document type can exist.
This interface may be implemented directly. For convenience, a base implementation is defined in EditorPart.

An editor part is added to the workbench in two stages:
1. An editor extension is contributed to the workbench registry. This extension defines the extension id, extension class, and the file extensions which are supported by the editor.
2. An editor part based upon the extension is created and added to the workbench when the user opens a file with one of the supported file extensions (or some other suitable form of editor input).
All editor parts implement the IAdaptable interface; extensions are managed by the platform's adapter manager.
