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_BEGIN_VERSIONED_NAMESPACE_DECL TAO_ECG_UDP_EH::TAO_ECG_UDP_EH | ( | TAO_ECG_Dgram_Handler * | recv | ) |
Initialization and termination methods.
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_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.
