Eclipse Platform
Release 3.2

org.eclipse.ui
Interface ISaveablesSource

All Known Implementing Classes:
CommonNavigator

public interface ISaveablesSource

Workbench parts that work in terms of units of saveability should implement this interface in order to provide better integration with workbench facilities like the Save command, prompts to save on part close or shutdown, etc.

IMPORTANT: As of 3.2, implementers of ISaveablesSource must satisfy the following conditions:

If any of these conditions are not met, it is undefined whether the Workbench will prompt to save dirty Saveables when closing parts.

These conditions may be relaxed in future releases.

Since:
3.2

Method Summary
 Saveable[] getActiveSaveables()
          Returns the saveables currently active in the workbench part.
 Saveable[] getSaveables()
          Returns the saveables presented by the workbench part.
 

Method Detail

getSaveables

public Saveable[] getSaveables()
Returns the saveables presented by the workbench part. If the return value of this method changes during the lifetime of this part, 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 method, or from its dispose method. Parts that implement IReusableEditor must notify when their input is changed by calling IReusableEditor.setInput(IEditorInput).

Returns:
the saveables presented by the workbench part

ISaveablesLifecycleListener

getActiveSaveables

public Saveable[] getActiveSaveables()
Returns the saveables currently active in the workbench part.

Certain workbench actions, such as Save, target only the active saveables in the active part. For example, the active saveables could be determined based on the current selection in the part.

Returns:
the saveables currently active in the workbench part
