Class WeightsTableDataSet

java.lang.Object
  org.das2.dataset.WeightsTableDataSet

All Implemented Interfaces:

DataSet, TableDataSet

public class WeightsTableDataSet
extends java.lang.Object
implements TableDataSet

WeightsTableDataSet wraps a TableDataSet and returns 0.0 if the data point is not valid, and non-zero (generally one) otherwise. This is intended to provide a consistent way to get the weights without having to handle the case where the weights plane doesn't exist.
