configure()

void trigger::TrigElectronProducer::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.
