virtual uint32_t rofl::crofchan_env::get_async_xid ( crofchan & chan )

protectedpure virtual

Acquires an OpenFlow transaction ID for an asynchronous message.

Parameters

chan	crofchan instance

virtual uint32_t rofl::crofchan_env::get_sync_xid	(	crofchan &	chan,
		uint8_t	msg_type = `0`,
		uint16_t	msg_sub_type = `0`
	)

protectedpure virtual

Acquires an OpenFlow transaction ID for a synchronous message.

Parameters

chan	crofchan instance

virtual void rofl::crofchan_env::handle_write	(	crofchan &	chan,
		const cauxid &	auxid
	)

protectedpure virtual

Called after a congestion situation has been resolved.

Note: This method is executed in the thread context of the underlying socket instance.

Parameters

chan	crofchan instance
auxid	auxiliary connection that is usable again

virtual void rofl::crofchan_env::recv_message	(	crofchan &	chan,
		const cauxid &	aux_id,
		rofl::openflow::cofmsg *	msg
	)

protectedpure virtual

Called upon reception of an OpenFlow message by the peer entity.

Note: This method is executed in the thread context of the underlying socket instance.

Parameters

virtual void rofl::crofchan_env::release_sync_xid	(	crofchan &	chan,
		uint32_t	xid
	)

protectedpure virtual

Releases a synchronous transaction ID after reception of an OpenFlow reply.

Parameters

chan	crofchan instance
