Handle

From GEANT2-JRA1 Wiki

A subscriber handle is a pointer to a server socket waiting to accept a specific set of data. A publisher will contact the server socket and send the data when it is ready (push).

A publisher handle is a pointer to a server socket where data can be fetched. A subscriber will contact the server socket and request data on some predefined interval (pull). This is not a measurement data request in the broader sense, that must have already happened for the publisher handle to have been created.
