Member Function Documentation

◆ getIOID()

virtual pvAccessID epics::pvAccess::ResponseRequest::getIOID ( ) const
pure virtual

Get I/O ID.


◆ getRequester()

virtual std::tr1::shared_ptr<ChannelBaseRequester> epics::pvAccess::ResponseRequest::getRequester ( )
pure virtual

used by MessageHandler and reportChannelStateChange().

May return NULL

◆ reportStatus()

virtual void epics::pvAccess::ResponseRequest::reportStatus ( Channel::ConnectionState  status)
pure virtual

Report status to clients (e.g.


statusto report.

◆ response()

virtual void epics::pvAccess::ResponseRequest::response ( Transport::shared_pointer const &  transport,
epics::pvData::int8  version,
epics::pvData::ByteBuffer *  payloadBuffer 
pure virtual

Notification response.


◆ send()

virtual void epics::pvAccess::TransportSender::send ( epics::pvData::ByteBuffer *  buffer,
TransportSendControl control 
pure virtualinherited

Called by transport.

By this call transport gives callee ownership over the buffer. Calls on TransportSendControl instance must be made from calling thread. Moreover, ownership is valid only for the time of call of this method. NOTE: these limitations allow efficient implementation.

Implemented in epics::pvAccess::BeaconEmitter.
