Class ShapeIterator
java.lang.Object
uk.ac.starlink.table.ShapeIterator
- All Implemented Interfaces:
- Iterator
- public class ShapeIterator
- extends Object
- implements Iterator
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).
