Method Detail

getLastActiveEditorPart

public IWorkbenchPart getLastActiveEditorPart()

setViewer

public void setViewer(TreeViewer viewer)

To set the Tree Viewer from outside. After calling this method a part listener will be added on active page which registers activation of editors that can be decorated.
Note: without setting a tree viewer the services of this class implementation will work properly.

Parameters:

viewer -

refreshViewer

public void refreshViewer()

Complete refresh of the viewer tree if needed.

refreshViewer

public void refreshViewer(Object object)

Collection can be provided as parameter. Refresh will be executed asynchronously for whole group of collection items in one runnable.

Parameters:

object - an viewer tree element or a collection of them.

updateViewer

public void updateViewer(Object element)

Updates the element of the viewer.

Parameters:

element - of the tree in question.

revealElement

public void revealElement(Object element)

getModelIdForWorkbenchPart

public String getModelIdForWorkbenchPart(IWorkbenchPart part)

applyStereotype

public void applyStereotype(EObject eObject)

Executes the operation of applying stereotypes on given EObject

Specified by:

applyStereotype in interface PluginExtensionOperationsListener

eObjectSelected

public void eObjectSelected(EObject eObject)

Notifies the extended plug-in that the new selection on an instance of EObject was registered.

Specified by:

eObjectSelected in interface PluginExtensionOperationsListener

setActivateViewFilter

public void setActivateViewFilter(boolean activateFilter)

Called by StereotypeApplicationsOnSelectedElementHandler

Parameters:

activateFilter - true or false

refreshDecorations

public void refreshDecorations(Collection<EObject> eObjects)

It calls the refreshDecoration(EObject) for each EObject.
Note: This method can be used to refresh decorations when loading or unloading profile applications.

Parameters:

eObjects - collection of EObjects for which decorations must be refreshed.

refreshDecoration

public void refreshDecoration(EObject eObject)

The method collects all stereotypes applied to eObject from profile applications that can be found for this model in ProfileApplicationRegistry and then informs active editor decorator to decorate the eObject.

Parameters:

eObject - that has stereotype applications

cleanUp

public void cleanUp()

The cleanup is executed if the profile application view in workbench is closing, but not the Workbench. If the workbench is closing, then the clean-up will be executed in IWorkbenchListener.preShutdown(IWorkbench, boolean) which calls clean-up for all profile applications in DecoratableEditorPartListener.cleanUpForAllEditorParts().

setProfileApplicationChanged

public void setProfileApplicationChanged()

This method will be called from ProfileApplicationDecoratorReflectiveItemProviderAdapterFactory when notification is fired that an attribute is changed in properties view. Notifications will be fired for every change, but we are here only interested in scenario when only one tree element is selected and we can find profile application decorator from it, otherwise this method will do nothing.

findProfileApplicationDecorator

public ProfileApplicationDecorator findProfileApplicationDecorator(EObject eObject)

If we need ProfileApplicationDecorator because of its extended functionalities, and calling EObject.eContainer() will eventually return ProfileApplication but we cannot cast it to ProfileApplicationDecorator. Thus, the easiest way to get it is to ask the ProfileApplicationRegistry, which this method does for you.

Parameters:

eObject -

Returns:
