Member Function Documentation

◆ channelDisconnect()

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
destroytrue for final disconnect.

Definition at line 198 of file pvAccess.h.

◆ channelRPCConnect()

virtual void epics::pvAccess::ChannelRPCRequester::channelRPCConnect ( const epics::pvData::Status &  status,
ChannelRPC::shared_pointer const &  operation 
)
pure virtual

RPC creation request satisfied.

Must check status.isOk().

On Success, a non-NULL 'operation' is provided. This is the same pointer which was, or will be, returned from Channel::createChannelRPC().

It is allowed to call ChannelRPC::request() from within this method.

◆ requestDone()

virtual void epics::pvAccess::ChannelRPCRequester::requestDone ( const epics::pvData::Status &  status,
ChannelRPC::shared_pointer const &  operation,
epics::pvData::PVStructure::shared_pointer const &  pvResponse 
)
pure virtual

RPC request (execution) completed.

Must check status.isOk().

On Success, a non-NULL 'pvResponse' is provided.

It is allowed to call ChannelRPC::request() from within this method.
