Class ShapeIterator

java.lang.Object
  uk.ac.starlink.table.ShapeIterator

All Implemented Interfaces:

java.util.Iterator<int[]>

public class ShapeIterator
extends java.lang.Object
implements java.util.Iterator<int[]>

Iterates over a shape array, as got from ValueInfo.getShape(). Will only work for a finite-valued array, not for one with a variable last dimension (negative dimension value). The object returned by the next method is an array with the same number of dimensions as the shape itself, giving the current position (the first returned value is an N-element array of zeros).
