Messaging::MessageCallbackHandler Class Reference

#include <messagecallbackhandler.h>

Detailed Description

Handles asynchronous message callbacks.

Allows us to perform callbacks whenever a message has been handled. Is primarily used for knowing whenever a get-something-from-another-thread-message has been handled.

For example, if we send a FetchSkinList message and want to have a callback for whenever it's handled, we can simply bind the message object to a function using the macro.

Example:

Ptr<Graphics::FetchSkinList> msg = Graphics::FetchSkinList::Create(); __Send(modelEntity, msg);
__SingleFireCallback(ViewerApplication, OnFetchedSkinList, this, msg.upcast<Messaging::Message>());

Which, when msg is handled will call this->OnFetchedSkinList with the message as argument. It sets up a specific callback delegate, not a generic one based on message type.
