Member Function Documentation

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

pure virtual

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.

Implemented in epics::pvDatabase::ChannelArrayLocal, epics::pvDatabase::ChannelRPCLocal, epics::pvDatabase::ChannelPutGetLocal, epics::pvDatabase::ChannelPutLocal, epics::pvDatabase::ChannelGetLocal, epics::pvAccess::ca::CAChannelPut, PDBGroupPut, epics::pvAccess::ca::CAChannelGet, PDBSinglePut, pvas::detail::SharedRPC, epics::pvAccess::ChannelRPCServiceImpl, pvas::detail::SharedPut, and epics::pvDatabase::ChannelProcessLocal.

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

pure virtual

Get a channel instance this request belongs to.

Returns

the channel instance.

Implemented in epics::pvDatabase::ChannelArrayLocal, epics::pvDatabase::ChannelRPCLocal, epics::pvDatabase::ChannelPutGetLocal, epics::pvDatabase::ChannelPutLocal, epics::pvDatabase::ChannelGetLocal, epics::pvAccess::ca::CAChannelPut, PDBGroupPut, epics::pvAccess::ca::CAChannelGet, PDBSinglePut, pvas::detail::SharedRPC, epics::pvAccess::ChannelRPCServiceImpl, pvas::detail::SharedPut, and epics::pvDatabase::ChannelProcessLocal.

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

pure virtual

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

Implemented in epics::pvDatabase::ChannelArrayLocal, epics::pvDatabase::ChannelRPCLocal, epics::pvDatabase::ChannelPutGetLocal, epics::pvDatabase::ChannelPutLocal, epics::pvDatabase::ChannelGetLocal, epics::pvAccess::ca::CAChannelPut, PDBGroupPut, epics::pvAccess::ca::CAChannelGet, PDBSinglePut, pvas::detail::SharedRPC, pvas::detail::SharedPut, epics::pvDatabase::ChannelProcessLocal, and epics::pvAccess::ChannelRPCServiceImpl.
