|

// CLASS DESCRIPTION (MNodeMessage)
|
||||
//
|
||||
// This class is used to register callbacks for dependency node messages
|
||||
// of specific dependency nodes.
|
||||
//
|
||||
// There are 4 add callback methods which will add callbacks for the
|
||||
// following messages
|
||||
// Attribute Changed
|
||||
// Attribute Added or Removed
|
||||
// Node Dirty
|
||||
// Name Changed
|
||||
//
|
||||
// The first parameter passed to each of the add callback methods is the
|
||||
// depenency node that will trigger the callback.
|
||||
//
|
||||
// Callbacks that are registered for attribute changed/addedOrRemoved messages
|
||||
// will be passed an AttributeMessage value as a parameter. This value
|
||||
// indicates the type of attribute message that has occurred. See the
|
||||
// enum for all available messages.
|
||||
//
|
||||
// Each method returns an id which is used to remove the callback.
|
||||
//
|
||||
// To remove a callback use MMessage::removeCallback.
|
||||
// All callbacks that are registered by a plug-in must be removed by that
|
||||
// plug-in when it is unloaded. Failure to do so will result in a fatal error.
