Overview

An Iterator that produces every coordinate in an IndexRegion in colexicographic (column-major) order. For example:

ColexIterator.cover([2, 3]).each.to_a # => [[0, 0], [1, 0], [0, 1], [1, 1], [0, 1], [1, 2]]

Defined in:

Constructors

• .new(idx_r : IndexRegion(I))

  Constructs an iterator that will provide every coordinate described by an IndexRegion.

• .new(region_literal : Indexable(I)) forall I

  Constructs an iterator that will provide every coordinate described by a region literal.

Instance Method Summary

• #advance! : Array(I) | Stop

  Advances the internal state of this StrideIterator and returns the new coord (or Iterator::Stop if iteration is finished).
