void CusCondTxtTreeViewObserver::AutoAttach ( )

virtual

If the observer knows which subject(s) to attach itself to, it'll do so with this call

Reimplemented from CObserver.

void CusCondTxtTreeViewObserver::AutoDetach ( )

virtual

If the observer knows which subject(s) to detach itself from, it'll do so with this call

Reimplemented from CObserver.

void CusCondTxtTreeViewObserver::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.

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

virtual

        Regular notification of a change in an observed subject; this method is called immediately after the

        change is made, it is not called on undo or redo.

Parameters

theChange	represents the change to an object, often this is the ClassID of the command that made the change
theSubject	is the subject that changed
protocol	is the interface of the subject's boss that changed
changedBy	is used to pass additional data about the change, often this is a pointer to the command that caused the change

See Also

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

IObserver::LazyUpdate for lazy notification

Implements IObserver.
