xal.model.alg.TwissTrackerPmq

All Implemented Interfaces:

Remote, IAlgorithm, IArchive, IContextAware

public class TwissTrackerPmq
extends TwissTracker

This class is a super class of the TwissTracker class meant to handle the special case of IdealPermMagQuad elements. There really is not much extra to do here, just look for the exception element and adjust the number of integration steps accordingly.

See the TwissTracker class for a complete description of the functionality
