Detailed Description

Event Handler for UDP messages.

Listens for messages on a UDP socket. When there is a message, calls handle_input () on a specified TAO_ECG_Dgram_Handler to inform it about message arrival.

NOT THREAD-SAFE.

Constructor & Destructor Documentation

TAO_ECG_UDP_EH::TAO_ECG_UDP_EH (  TAO_ECG_Dgram_Handler *  recv  )

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

TAO_ECG_UDP_EH::~TAO_ECG_UDP_EH (  void   )  [virtual]

Destructor.

Member Function Documentation

ACE_INLINE ACE_SOCK_Dgram & TAO_ECG_UDP_EH::dgram (  void   )

Obtain the dgram, this is one of those "controlled violations of type safety", allowing the user to setup options and gain access to low-level features.

int TAO_ECG_UDP_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_UDP_EH::open (  const ACE_INET_Addr &  ipaddr, int  reuse_addr = 0 )

Open the datagram and register itself with this->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_UDP_EH::shutdown (  void   )  [virtual]

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