public class MatrixLineagePair
extends org.apache.commons.lang3.tuple.MutablePair<MatrixObject,LineageItem>

Class to represent the relation between a MatrixObject and the respective LineageItem. This class couples the MatrixObject with its LineageItem, where the LineageItem is treated like meta information and the most important methods of the MatrixObject are included as a simple forwarding to the MatrixObject.
