TAO_ECG_Simple_Mcast_EH Class Reference

Simple Event Handler for mcast messages. Listens for messages on a single mcast group. Useful in environments where event traffic is not separated into different groups. Calls handle_input (ACE_SOCK_Dgram_Mcast dgram) on a specified TAO_ECG_Dgram_Handler to inform it about message arrival. More...

Detailed Description

Simple Event Handler for mcast messages. Listens for messages on a single mcast group. Useful in environments where event traffic is not separated into different groups. Calls handle_input (ACE_SOCK_Dgram_Mcast dgram) on a specified TAO_ECG_Dgram_Handler to inform it about message arrival.

NOT THREAD-SAFE.

(

)

Initialization and termination methods.

Constructor. Messages received by this EH will be forwarded to the <recv>.

TAO_ECG_Simple_Mcast_EH::~TAO_ECG_Simple_Mcast_EH ( void  )

virtual

Destructor.

Member Function Documentation

int TAO_ECG_Simple_Mcast_EH::handle_input ( ACE_HANDLE  fd )

virtual

Main method - reactor callback. Notify <receiver_> that <dgram_> is ready for reading.

Reimplemented from ACE_Event_Handler.

int TAO_ECG_Simple_Mcast_EH::open	(	const char *	mcast_addr,
		const ACE_TCHAR *	net_if = 0
	)

Join the specified multicast group and register itself with the reactor. To insure proper resource clean up, if open () is successful, the user MUST call shutdown () when handler is no longer needed (and its reactor still exists).

int TAO_ECG_Simple_Mcast_EH::shutdown ( void  )

virtual

TAO_ECG_Handler_Shutdown method. Unsubscribe from the reactor and close the datagram.

Implements TAO_ECG_Handler_Shutdown.
