Abstract base implementation of a text editor.

Subclasses are responsible for configuring the editor appropriately. The standard text editor, TextEditor, is one such example.

If a subclass calls setEditorContextMenuId the argument is used as the id under which the editor's context menu is registered for extensions. If no id is set, the context menu is registered under [editor_id].EditorContext whereby [editor_id] is replaced with the editor's part id. If the editor is instructed to run in version 1.0 context menu registration compatibility mode, the latter form of the registration even happens if a context menu id has been set via setEditorContextMenuId. If no id is set while in compatibility mode, the menu is registered under DEFAULT_EDITOR_CONTEXT_MENU_ID.

If a subclass calls setRulerContextMenuId the argument is used as the id under which the ruler's context menu is registered for extensions. If no id is set, the context menu is registered under [editor_id].RulerContext whereby [editor_id] is replaced with the editor's part id. If the editor is instructed to run in version 1.0 context menu registration compatibility mode, the latter form of the registration even happens if a context menu id has been set via setRulerContextMenuId. If no id is set while in compatibility mode, the menu is registered under DEFAULT_RULER_CONTEXT_MENU_ID.

As of 3.5, contributers can contribute editor and ruler context menu actions to all subclasses of this class by using COMMON_EDITOR_CONTEXT_MENU_ID and COMMON_RULER_CONTEXT_MENU_ID.

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

Specified by:: init in interface IEditorPart
Specified by:: init in class EditorPart

setInputWithNotify

protected final void setInputWithNotify(

Description copied from class: EditorPart

Sets the input to this editor and fires a PROP_INPUT property change if the input has changed. This is the convenience method implementation.

Note that firing a property change may cause other objects to reach back and invoke methods on the editor. Care should be taken not to call this method until the editor has fully updated its internal state to reflect the new input.

Overrides:: setInputWithNotify in class EditorPart

Parameters:: input - the editor input

setInput

public final void setInput(
IEditorInput input)

Description copied from class: EditorPart

Sets the input to this editor. This method simply updates the internal member variable.

Unlike most of the other set methods on this class, this method does not fire a property change. Clients that call this method from a subclass must ensure that they fire an IWorkbenchPartConstants.PROP_INPUT property change after calling this method but before leaving whatever public method they are in. Clients that expose this method as public API must fire the property change within their implementation of setInput.

Note that firing a property change may cause listeners to immediately reach back and call methods on this editor. Care should be taken not to fire the property change until the editor has fully updated its internal state to reflect the new input.

Specified by:: setInput in interface IReusableEditor
Overrides:: setInput in class EditorPart

Parameters:: input - the editor input

getSaveables

public 
Saveable[] getSaveables()

Description copied from interface: ISaveablesSource

Returns the saveables presented by the workbench part. If the return value of this method changes during the lifetime of this part (i.e. after initialization and control creation but before disposal) the part must notify an implicit listener using ISaveablesLifecycleListener.handleLifecycleEvent(SaveablesLifecycleEvent).

Additions of saveables to the list of saveables of this part are announced using an event of type SaveablesLifecycleEvent.POST_OPEN. Removals are announced in a two-stage process, first using an event of type SaveablesLifecycleEvent.PRE_CLOSE followed by an event of type SaveablesLifecycleEvent.POST_CLOSE. Since firing the PRE_CLOSE event may trigger prompts to save dirty saveables, the cancellation status of the event must be checked by the part after the notification. When removing only non-dirty saveables, POST_CLOSE notification is sufficient.

The listener is obtained from the part site by calling partSite.getService(ISaveablesLifecycleListener.class).

The part must not notify from its initialization methods (e.g. init or createPartControl), or from its dispose method. Parts that implement IReusableEditor must notify when their input is changed through IReusableEditor.setInput(IEditorInput).

Specified by:: getSaveables in interface ISaveablesSource

Returns:: the saveables presented by the workbench part
See Also:: ISaveablesLifecycleListener

getActiveSaveables

public 
Saveable[] getActiveSaveables()
