Detailed Description
Abstract base interface for a client to receive the results of a query.
An instance of this interface must be passed to Scope::search(). Results for the query are delivered to the client by the scopes run time by invoking the appropriate push method.
If the implementation of a push method throws an exception, the scopes runtime calls ListenerBase::finished() with an 'Error' status.
