void epics::pvAccess::ServerGetFieldRequesterImpl::destroy ( )

virtual

Destroy this instance.

Implements epics::pvAccess::Destroyable.

void epics::pvAccess::ServerGetFieldRequesterImpl::getDone	(	const epics::pvData::Status &	status,
		epics::pvData::FieldConstPtr const &	field
	)

virtual

Check status.isOk() to determine success. On success the 'field' will be non-NULL. On failure 'field' will be NULL.

Parameters

status	Completion status.
field	The Structure for the request.

Implements epics::pvAccess::GetFieldRequester.

virtual std::tr1::shared_ptr<ChannelRequest> epics::pvAccess::ServerGetFieldRequesterImpl::getOperation ( )

inlinevirtual

The Operation associated with this Requester, except for GetField and Monitor (which are special snowflakes...)

Implements epics::pvAccess::BaseChannelRequester.

void epics::pvAccess::ServerGetFieldRequesterImpl::send	(	epics::pvData::ByteBuffer *	buffer,
		TransportSendControl *	control
	)

virtual

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.

Implements epics::pvAccess::TransportSender.
