• @PanicsAtCaller Public New(width: Int, height: Int, fill: T) constructor #

  A Grid width cells across and height down, each holding fill. A negative size panics, and so does one with more cells than an Int counts.

• Public Property Width: Int property #

  How many cells wide it is.

• Public Property Height: Int property #

  How many cells high it is.

• Public Property Count: Int property #

  How many cells it has, Width times Height.

• Public Method InBounds(x: Int, y: Int): Bool method #

  Whether (x, y) is one of the Grid's cells.

• @PanicsAtCaller Operator [](x: Int, y: Int): T operator #

  The value at (x, y). One outside the Grid panics.

• @PanicsAtCaller Operator []=(x: Int, y: Int, value: T) operator #

  Sets the value at (x, y) to value. One outside the Grid panics.

• @PanicsAtCaller Public Method Neighbors4(x: Int, y: Int): (Int, Int)[] method #

  The positions beside (x, y) that are in the Grid: above, left, right, and below it.

• @PanicsAtCaller Public Method Neighbors8(x: Int, y: Int): (Int, Int)[] method #

  The positions around (x, y) that are in the Grid, its corners too, row by row.

• Public Method Fill(value: T) method #

  Gives every cell the value.

• Public Method ToArray(): T[] method #

  The values, row by row, in a new array.

• Public Method Clone(): Grid<T> method #

  A new Grid with the same size and values.

• Public Method Iterate(): GridIterator<T> method #

  The values, row by row.
