BooleanArray

A fixed-size, mutable array of Boolean values.

Indices start at zero and end at size - 1. Changing an element does not change the array length. Equality compares array identity, not element contents.

The size-only constructor fills every element with false. The initializer constructor calls its callback once for each index, in ascending order.

Constructors

BooleanArray

constructor(size: Int)

Creates an array with size elements, each initially false.

constructor(size: Int, init: (Int) -> Boolean)

Creates an array by invoking init once for each index in ascending order.

Properties

size

external val size: Int

The number of elements in this array; always non-negative and unchanged after creation.

Functions

copyInto

external fun BooleanArray.copyInto(destination: BooleanArray, destinationOffset: Int = 0, startIndex: Int = 0, endIndex: Int = size): BooleanArray

Copies this range into destination, supporting overlapping ranges, and returns it.

copyOf

external fun BooleanArray.copyOf(): BooleanArray

Returns a new array containing the same elements.

external fun BooleanArray.copyOf(newSize: Int): BooleanArray

Returns a resized copy, padding extra elements with false.

get

operator external fun get(index: Int): Boolean

Returns the element at index.

iterator

operator external fun iterator(): BooleanIterator

Structural declaration for direct array loops; stored iterators are not executable.

set

operator external fun set(index: Int, value: Boolean)

Replaces the element at index with value.
