Reading Event Data

Data collections are read from the event using the get method of the EventHeader class which will return a list of objects.

Code Block

language	java

public void process(EventHeader event) {        
    List<CalorimeterHit> hits = event.get(CalorimeterHit.class, inputCollection);
    for (CalorimeterHit hit : hits) {
        System.out.println("calorimeter hit has energy " + hit.getCorrectedEnergy() + " GeV.");
    }
}

You may also get all collections of a given type by not providing a collection name which will return a "list of lists."

Code Block

language	java

public void process(EventHeader event) {        
    List<List<CalorimeterHit>> collections = event.get(CalorimeterHit.class);
    for (List<CalorimeterHit> hits : collections) {    
        for (CalorimeterHit hit : hits) {
            System.out.println("calorimeter hit has energy " + hit.getCorrectedEnergy() + " GeV.");
        }
    }
}
