Class TransferMapLoader

java.lang.Object
xal.extension.jels.model.elem.TransferMapLoader
public class TransferMapLoader extends Object
Taking care of loading and interpolating transfer matrices from a file.
  • loader = TransferMapLoader.getInstance(URI tmFile) returns an instance while the file is being loaded
  • el_tm = loader.prepare(double position, double length) prepares TransferMaps class for an element (lazily)
  • el_tm.transferMap(IProbe p, double l) on first call loads all the elements It returns interpolated transfer map for specific range
