Description
Called by subscribable objects when they change.
The Subscribe method is called by subscribable objects when they change, as long as the subscription is active. If ISubscription has Unsubscribe called on it, change notifications should cease.
The ANotification parameter specifies the callback routine that is called by the wrapper that implements this interface whenever the value held by the wrapper changes.
Subscribe returns the subscription reference corresponding to this subscribable object.
