IntObjectHashMap

open class IntObjectHashMap<VType> @JvmOverloads constructor(expectedElements: Int, loadFactor: Double = DEFAULT_LOAD_FACTOR.toDouble()) : Iterable<IntObjectHashMap.IntObjectCursor<VType>> , Accountable, Cloneable<IntObjectHashMap<VType>>

A hash map of int to Object, implemented using open addressing with linear probing for collision resolution. Supports null values.

Mostly forked and trimmed from com.carrotsearch.hppc.IntObjectHashMap

github: https://github.com/carrotsearch/hppc release 0.10.0

Constructors

IntObjectHashMap

@JvmOverloads

constructor(expectedElements: Int, loadFactor: Double = DEFAULT_LOAD_FACTOR.toDouble())

constructor()

New instance with sane defaults.

constructor(map: IntObjectHashMap<VType?>)

Create a hash map from all key-value pairs of another map.

Types

Companion

object Companion

IntObjectCursor

class IntObjectCursor<VType>

Forked from HPPC, holding int index,key and value

KeysContainer

inner class KeysContainer : Iterable<IntCursor>

A view of the keys inside this hash map.

ValuesContainer

inner class ValuesContainer : Iterable<ObjectCursor<VType?>?>

A view over the set of values of this map.

Properties

childResources

open val childResources: MutableCollection<Accountable>

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).

isEmpty

val isEmpty: Boolean

keys

var keys: IntArray?

The array holding keys.

values

var values: Array<Any?>?

The array holding values.

Functions

clear

fun clear()

clone

open override fun clone(): IntObjectHashMap<VType>

containsKey

fun containsKey(key: Int): Boolean

ensureCapacity

fun ensureCapacity(expectedElements: Int)

Ensure this container can hold at least the given number of keys (entries) without resizing its buffers.

equals

open operator override fun equals(obj: Any?): Boolean

get

operator fun get(key: Int): VType?

getOrDefault

fun getOrDefault(key: Int, defaultValue: VType?): VType?

hashCode

open override fun hashCode(): Int

indexExists

fun indexExists(index: Int): Boolean

indexGet

fun indexGet(index: Int): VType?

indexInsert

fun indexInsert(index: Int, key: Int, value: VType?)

indexOf

fun indexOf(key: Int): Int

indexRemove

fun indexRemove(index: Int): VType?

indexReplace

fun indexReplace(index: Int, newValue: VType?): VType?

iterator

open operator override fun iterator(): Iterator<IntObjectHashMap.IntObjectCursor<VType>>

keys

fun keys(): IntObjectHashMap.KeysContainer

Returns a specialized view of the keys of this associated container.

put

fun put(key: Int, value: VType?): VType?

putAll

fun putAll(iterable: Iterable<out IntObjectHashMap.IntObjectCursor<out VType?>>): Int

putIfAbsent

fun putIfAbsent(key: Int, value: VType?): Boolean

Trove-inspired API method. An equivalent of the following code:

ramBytesUsed

open override fun ramBytesUsed(): Long

Return the memory usage of this object in bytes. Negative values are illegal.

release

fun release()

remove

fun remove(key: Int): VType?

size

fun size(): Int

toString

open override fun toString(): String

Convert the contents of this map to a human-friendly string.

values

fun values(): IntObjectHashMap.ValuesContainer
