Member Function Documentation

cancel()

virtual void epics::pvAccess::ChannelRequest::cancel ( )

pure virtualinherited

Cancel any pending request.

Completion will be reported via request's response callback:

• if cancel() request is issued after the request was already complete, request success/failure completion will be reported and cancel() request ignored.
• if the request was actually canceled, cancellation completion is reported.

getChannel()

virtual std::tr1::shared_ptr<Channel> epics::pvAccess::ChannelRequest::getChannel ( )

pure virtualinherited

Get a channel instance this request belongs to.

Returns

the channel instance.

getGet()

virtual void epics::pvAccess::ChannelPutGet::getGet ( )

pure virtual

Get the get PVStructure.

The record will not be processed. Completion status is reported by calling ChannelPutGetRequester.getGetDone() callback.

getPut()

virtual void epics::pvAccess::ChannelPutGet::getPut ( )

pure virtual

Get the put PVStructure.

The record will not be processed. Completion status is reported by calling ChannelPutGetRequester.getPutDone() callback.

lastRequest()

virtual void epics::pvAccess::ChannelRequest::lastRequest ( )

pure virtualinherited

Announce next request as last request.

When last request will be completed (regardless of completion status) the remote and local instance will be destroyed.

putGet()

virtual void epics::pvAccess::ChannelPutGet::putGet ( epics::pvData::PVStructure::shared_pointer const &  pvPutStructure, epics::pvData::BitSet::shared_pointer const &  putBitSet  )

pure virtual

Issue a put/get request.

If process was requested when the ChannelPutGet was created this is a put, process, get. Completion status is reported by calling ChannelPutGetRequester.putGetDone() callback.

Parameters

pvPutStructure	The PVStructure that holds the putData.
putBitSet	putPVStructure bit-set (selects what fields to put).
