Class ResultMatrix

java.lang.Object
  waelti.statistics.queries.ResultMatrix

All Implemented Interfaces:

java.lang.Iterable<java.lang.Object[]>

public class ResultMatrix
extends java.lang.Object
implements java.lang.Iterable<java.lang.Object[]>

A result matrix represents the results of a query. A normal query will compute a two-dimensional matrix. This class wraps a list so that all data points can be accessed by its coordinates x and y. Where x is the horizontal and y the vertical dimension. x therefore denotes the position of a column whereas y denotes the position of a row. The position computed from the upper left corner starting with (0,0), y denoting the position downwards and x the position to the left.
