IExtensionPointFilter berry::ExtensionTracker::CreateExtensionPointFilter ( const SmartPointer< IExtensionPoint > & xpt )

static

Return an instance of filter matching all changes for the given extension point.

Parameters

xpt	the extension point

Returns: a filter

IExtensionPointFilter berry::ExtensionTracker::CreateExtensionPointFilter ( const QList< SmartPointer< IExtensionPoint > > & xpts )

static

Return an instance of filter matching all changes for the given extension points.

Parameters

xpts	the extension points used to filter

Returns: a filter

IExtensionPointFilter berry::ExtensionTracker::CreateNamespaceFilter ( const QString & id )

static

Return an instance of filter matching all changes from a given plugin.

Parameters

id	the plugin id

Returns: a filter

QList< SmartPointer< Object > > berry::ExtensionTracker::GetObjects ( const SmartPointer< IExtension > & extension ) const

overridevirtual

Return all the objects that have been associated with the given extension. All objects registered strongly will be return unless they have been unregistered. The objects registered softly or weakly may not be returned if they have been garbage collected. Return an empty array if no associations exist.

Parameters

extension the extension for which the object must be returned

Returns: the array of associated objects

		ReferenceType	referenceType
	)

overridevirtual

Create an association between the given extension and the given object. The referenceType indicates how strongly the object is being kept in memory. There are 2 possible values: REF_STRONG and REF_WEAK.

Parameters

extension	the extension
object	the object to associate with the extension
referenceType	one of REF_STRONG, REF_WEAK
