typedef MessageType	message_type
	Stores the message template type for external reference.

Public Member Functions

	TypedStateFlow (Service *service)
	Constructor.
virtual	~TypedStateFlow ()
	Destructor.
void	send (MessageType *msg, unsigned priority=UINT_MAX) OVERRIDE
	Sends a message to the state flow for processing.
Public Member Functions inherited from FlowInterface< MessageType >
virtual Pool *	pool ()
virtual MessageType *	type_helper ()
	This function is never user in the code, but GDB can use it to infer the correct message types.
MessageType *	alloc ()
	Synchronously allocates a message buffer from the pool of this flow.
void	alloc_async (Executable *target)
	Asynchronously allocates a message buffer from the pool of this flow.

Additional Inherited Members
Static Public Member Functions inherited from FlowInterface< MessageType >
static MessageType *	cast_alloc (QMember *entry)
	Down casts and initializes an asynchronous allocation result to the appropriate flow's buffer type.
Protected Member Functions inherited from TypedStateFlow< MessageType, Base >
void	release () OVERRIDE
	Unrefs the current buffer.
void	return_buffer ()
	For state flows that are operated using invoke_subflow_and_wait this is a way to hand back the buffer to the caller.
MessageType *	message ()
MessageType *	transfer_message ()
	Releases ownership of the current message.
