LongArray

class LongArray(size: Int)(source)

An array of longs. When targeting the JVM, instances of this class are represented as long[].

Constructors

LongArray

fun LongArray(size: Int, init: (Int) -> Long)

Creates a new array of the specified size, where each element is calculated by calling the specified init function.

LongArray

fun LongArray(size: Int)

Creates a new array of the specified size, with all elements initialized to zero.

Functions

get

operator fun get(index: Int): Long

Returns the array element at the given index. This method can be called using the index operator.

Since Kotlin 1.0

iterator

operator fun iterator(): LongIterator

Creates an iterator over the elements of the array.

Since Kotlin 1.0

set

operator fun set(index: Int, value: Long)

Sets the element at the given index to the given value. This method can be called using the index operator.

Since Kotlin 1.0

Properties

size

val size: Int

Returns the number of elements in the array.

Since Kotlin 1.0

Extensions

asList

actual fun LongArray.asList(): List<Long>

Returns a List that wraps the original array.

Since Kotlin 1.0

binarySearch

fun LongArray.binarySearch(element: Long, fromIndex: Int = 0, toIndex: Int = size): Int

Searches the array or the range of the array for the provided element using the binary search algorithm. The array is expected to be sorted, otherwise the result is undefined.

Since Kotlin 1.0

copyOf

actual inline fun LongArray.copyOf(): LongArray

Returns new array which is a copy of the original array.

Since Kotlin 1.0

actual inline fun LongArray.copyOf(newSize: Int): LongArray

Returns new array which is a copy of the original array, resized to the given newSize. The copy is either truncated or padded at the end with zero values if necessary.

Since Kotlin 1.0

copyOfRange

@JvmName(name = "copyOfRangeInline")

actual inline fun LongArray.copyOfRange(fromIndex: Int, toIndex: Int): LongArray

Returns a new array which is a copy of the specified range of the original array.

Since Kotlin 1.0

elementAt

actual inline fun LongArray.elementAt(index: Int): Long

Returns an element at the given index or throws an IndexOutOfBoundsException if the index is out of bounds of this array.

Since Kotlin 1.0

fill

actual fun LongArray.fill(element: Long, fromIndex: Int = 0, toIndex: Int = size)

Fills this array or its subrange with the specified element value.

Since Kotlin 1.0

sort

actual fun LongArray.sort()

Sorts the array in-place.

Since Kotlin 1.0

actual fun LongArray.sort(fromIndex: Int = 0, toIndex: Int = size)

Sorts a range in the array in-place.

Since Kotlin 1.0
