This is a virtual class that can be implemented by a client that uses PvaClientGet. It has the methods:
virtual void channelGetConnect( const Status& status, PvaClientGetPtr const & clientGet) {} virtual void getDone( const Status& status, PvaClientGetPtr const & clientGet) = 0;
The client must call
pvaClientGet->setRequester(shared_from_this());
after creating an instance of PvaClientGet.
