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

pure virtualinherited

Get a channel instance this request belongs to.

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::ChannelRPC::request ( epics::pvData::PVStructure::shared_pointer const & pvArgument )

pure virtual

Issue an RPC request to the channel.

Completion status is reported by calling ChannelRPCRequester::requestDone() callback, which may be called from this method.

Precondition: The underlying Channel must be connected, and this ChannelRPC valid. Otherwise the ChannelRPCRequester::requestDone() is called with an error.

Postcondition: After calling request(), the requestDone() callback will be called at some later time. May call ChannelRPC::cancel() to request to abort() this operation.

Parameters

pvArgument The argument structure for an RPC request.
