Detailed Description

template<class T>
class PureMVC::IObserverTemplated< T >

The interface definition for a PureMVC Observer.

In PureMVC, IObserver implementors assume these responsibilities:

• Encapsulate the notification (callback) method of the interested object.
• Encapsulate the notification context (this) of the interested object.
• Provide methods for setting the interested object' notification method and context.
• Provide a method for notifying the interested object.

PureMVC does not rely upon underlying event models such as the one provided with Flash, and ActionScript 3 does not have an inherent event model.

The Observer Pattern as implemented within PureMVC exists to support event driven communication between the application and the actors of the MVC triad.

An Observer is an object that encapsulates information about an interested object with a notification method that should be called when an INotification is broadcast. The Observer then acts as a proxy for notifying the interested object.

Observers can receive Notifications by having their notifyObserver method invoked, passing in an object implementing the INotification interface, such as a subclass of Notification.

Member Function Documentation

virtual bool PureMVC::IObserverRestricted::compareNotifyContext

(

intptr_t

memoryAddress

)

[pure virtual, inherited]

Compare an object's memory address to the notification context's memory address.

Parameters:

memoryAddress

the object to compare

Returns:

boolean indicating if the object and the notification context are the same

Implemented in PureMVC::Observer< T >.

virtual void PureMVC::IObserverRestricted::notifyObserver

(

INotification *

notification

)

[pure virtual, inherited]

A callback.

Call the Observer's callback function in the context of the Observer.

Implemented in PureMVC::Observer< T >.

template<class T >

virtual void PureMVC::IObserverTemplated< T >::setNotifyContext

(

T *

notifyContext

)

[pure virtual]

Set the notification context.

Parameters:

notifyContext

the notification context (this) of the interested object

Implemented in PureMVC::Observer< T >.

template<class T >

virtual void PureMVC::IObserverTemplated< T >::setNotifyMethod

(

void(T::*)(INotification *)

fptr

)

[pure virtual]

Set the notification method.

The notification method should take one parameter of type INotification

Parameters:

notifyMethod

the notification (callback) method of the interested object
