Member Function Documentation

configure()

void trigger::TrigEcalClusterProducer::configure ( framework::config::Parameters & parameters )

virtual

Callback for the EventProcessor to configure itself from the given set of parameters.

The parameters a processor has access to are the member variables of the python class in the sequence that has className equal to the EventProcessor class name.

For an example, look at MyProcessor.

Parameters

parameters

Parameters for configuration.

Reimplemented from framework::EventProcessor.

Definition at line 12 of file TrigEcalClusterProducer.cxx.

                                                                     {
  hitCollName_ = ps.getParameter<std::string>("hitCollName");
  clusterCollName_ = ps.getParameter<std::string>("clusterCollName");
}

produce()

void trigger::TrigEcalClusterProducer::produce ( framework::Event & event )

virtual

Process the event and put new data products into it.

Parameters

event

The Event to process.

Implements framework::Producer.
