Destructor.

Member Function Documentation

void LnkWtchCacheManager::AutoAttach ( void  )

virtual

Attach protocols of interest.

Reimplemented from CObserver.

void LnkWtchCacheManager::AutoDetach ( void  )

virtual

Detach protocols of interest.

Reimplemented from CObserver.

void LnkWtchCacheManager::LazyUpdate ( ISubject *  theSubject, const PMIID &  protocol, const LazyNotificationData *  data  )

virtual

Lazy notification of a change in an observed subject; this method is called after the transaction in which the change was performed completes and after undo or redo.

Parameters

theSubject	is the subject that changed
protocol	is the interface of the subject's boss that changed
data	lazy notification data or nil. Observers must be able to handle a call that has nil data. In certain low memory conditions the lazy notification data passed to ISubject::ModelChange may not be passed on to observers. The observer must be able to work without data in which case the observer would usually refresh its entire state by re-examining all objects of interest. See LazyNotificationData for documentation.

See Also

ISubject::AttachObserver(IObserver*, const PMIID&, AttachmentType) to receive lazy notification attach to the subject by calling this method specifying an attachment type of lazy, or, both if you also want regular notification.

IObserver::Update for regular notification

Reimplemented from CObserver.

virtual void LnkWtchCacheManager::Update ( const ClassID &  theChange, ISubject *  theSubject, const PMIID &  protocol, void *  changedBy  )

inlinevirtual

Handle broadcasts on protocols of interest.

Parameters

theChange	specifies the class ID of the change to the subject. Frequently this is a command ID.
theSubject	points to the ISubject interface for the subject that has changed.
protocol	specifies the ID of the changed interface on the subject boss.
changedBy	points to additional data about the change. Often this pointer indicates the class ID of the command that has caused the change.

Implements IObserver.
