Detailed Description

Maintains information about an outgoing endpoint.

UDP senders can share a single endpoint to send UDP packets, but there is more state associated with this endpoint than its datagram SAP; for instance we need to keep track of the request id.

Member Function Documentation

ACE_SOCK_Dgram& TAO_ECG_UDP_Out_Endpoint::dgram

(

void

)

Obtain the datagram associated with this endpoint. Clients of this class must open, and register (if necessary) this datagram.

CORBA::Boolean TAO_ECG_UDP_Out_Endpoint::is_loopback

(

const ACE_INET_Addr &

from

)

The endpoint can detect if a data-gram was sent by itself, this is useful to ignore or remove messages sent by the same process.
