virtual void epics::pvAccess::ChannelBaseRequester::channelDisconnect ( bool destroy )

inlinevirtualinherited

Notification when underlying Channel becomes DISCONNECTED or DESTORYED.

(re)connection is notified through a sub-class *Connect() method.

Any in-progress get()/put()/request()/start() is implicitly cancel()'d or stop()'d before this method is called.

Ownership of any PVStructures passed to completion callbacks (eg. ChannelGetRequester::getDone() ) is returned the operation

Parameters

destroy true for final disconnect.

virtual void epics::pvAccess::MonitorRequester::monitorConnect	(	epics::pvData::Status const &	status,
		MonitorPtr const &	monitor,
		epics::pvData::StructureConstPtr const &	structure
	)

pure virtual

Underlying Channel is connected and operation setup is complete.

Call start() to begin subscription updates.

Parameters

status	Completion status.
monitor	The monitor
structure	The structure defining the data.

virtual void epics::pvAccess::MonitorRequester::monitorEvent ( MonitorPtr const & monitor )

pure virtual

Monitor queue is not empty.

The requester must call Monitor.poll to get data.

Parameters

monitor The monitor.

virtual void epics::pvAccess::MonitorRequester::unlisten ( MonitorPtr const & monitor )

pure virtual

No more subscription update will be sent.

Parameters

monitor The monitor.
