Member Function Documentation

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.

virtual void epics::pvAccess::ChannelPut::get ( )

pure virtual

Get the current data.

Ownership transfer as with ChannelGet::get()

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

pure virtualinherited

Get a channel instance this request belongs to.

Returns

the channel instance.

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.

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

pure virtual

Put data to a channel.

Completion status is reported by calling ChannelPutRequester::putDone()

Ownership of the PVStructure is transfered to the ChannelPut until ChannelPutRequester::putDone() or ChannelPutRequester::channelDisconnect() is called.

Parameters

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