public interface IEditorPart

extends IWorkbenchPart, ISaveablePart

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.

Constant Field Values

Method Detail

getEditorInput

public IEditorInput getEditorInput()

Returns the input for this editor. If this value changes the part must fire a property listener event with PROP_INPUT.

Returns:

the editor input

getEditorSite

public IEditorSite getEditorSite()

Returns the site for this editor. The method is equivalent to (IEditorSite) getSite().

Returns:

the editor site

init

public void init(IEditorSite site,
                 IEditorInput input)
          throws PartInitException

Initializes this editor with the given editor site and input.

This method is automatically called shortly after the part is instantiated. It marks the start of the part's lifecycle. The IWorkbenchPart.dispose method will be called automically at the end of the lifecycle. Clients must not call this method.

Implementors of this method must examine the editor input object type to determine if it is understood. If not, the implementor must throw a PartInitException

Parameters:

site - the editor site

input - the editor input

Throws:

PartInitException - if this editor was not initialized successfully
