Definition at line 353 of file remote.h.

Member Function Documentation

getIOID()

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

pure virtual

Get I/O ID.

Returns

ioid

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.

disconnected).

Parameters

status

to 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.

Parameters

transport
version
payloadBuffer

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.
