void* Linker::Run(void *)

Mix linker Run() method. Processes all messages from the incoming queue and inserts them into its internal structures. Has to watch if a message is already completed and then it kinks all its chunks together and passes the final message further to Majordomo for processing.

Returns:

void pointer

void Linker::Shutdown()

Prepare for clean shutdown. This method should implement all the tasks necessary for preparation for a clean shutdown like saving inconsistent data to disk etc. Now it is empty as Linker is completely stateless as the loss of some partially received messages is not fatal. return void

GMessage* Linker::StoreChunk(GMessage * chunk)

Store chunk of message into internal structures. Actually performs the task of storing message into its internal structures, checking for Message ID conflicts and checking if the message is already complete. If that is true than a completely linked message is returned.

Returns:

Completely linked message if any else NULL.

Parameters:

chunk - Message from network that represents one chunk of original message and as such has to be linked with all the others to reconstruct it.
