Class SquidIterators.RectangleFromBottomLeftToTopRight

java.lang.Object

squidpony.squidgrid.iterator.SquidIterators.RectangleFromBottomLeftToTopRight

All Implemented Interfaces:

Iterator<Coord>, SquidIterator

Enclosing class:

SquidIterators

public static class SquidIterators.RectangleFromBottomLeftToTopRight
extends Object
implements SquidIterator

An iterator that starts from a cell and iterates from the bottom left to the top right, in the rectangle defined by the given width and height. Widths and heights are like list-sizes w.r.t indexes. So a rectangle of width or height 0 is empty, a rectangle of width and height 1 has one cell, a rectangle of width and height 2 has four cells, etc.

Put differently, the rectangle whose bottom left is (x, y) and has width and height 2, contains the cells (x, y), (x + 1, y), (x, y - 1), and (x + 1, y - 1); but it does NOT contain (x + 2, y), nor (x + 2, y - 1), nor (x + 2, y - 2).
