Member Function Documentation

void OpMessageHandler::addMessage	(	const OpMessage &	lrMessage,
		Op *	lpSourceOp,
		const std::vector< OpTree * > &	lrAffectedTrees
	)

addMessage only actually adds a new message if it is unique - i. e. if its data (other than the ID) doesn't match any message currently present.
