Example 7: Communicating with ParameterMQServer

This example shows how to communicate with the ParameterMQServer, that retrieves parameters from FairRuntimeDb.

The fill_parameters.C ROOT macro can be used to generate the parameter file for the server to read from. The generated file will contain paramters with the name FairMQExParamsParOne for run IDs 2000-2099.

FairMQExample7Client device requests parameter data from ParameterMQServer via REQ-REP pattern. The request contains parameter name and run ID.

The parameter name can be configured via command line (--parameter-name, default is FairMQExParamsParOne) and the run ID is hardcoded for this example.
