ArrayList

kotlin-stdlib / kotlin.collections / ArrayList

typealias ArrayList<E> = ArrayList<E>

Platform and version requirements: Kotlin 1.1, JVM

open class ArrayList<E> : 
    AbstractMutableList<E>, 
    RandomAccess

Platform and version requirements: JS

Provides a MutableList implementation, which uses a resizable array as its backing storage.

This implementation doesn't provide a way to manage capacity, as backing JS array is resizeable itself. There is no speed advantage to pre-allocating array sizes in JavaScript, so this implementation does not include any of the capacity and "growth increment" concepts.

Constructors

<init>

ArrayList(capacity: Int = 0)

Creates an empty ArrayList.

ArrayList(elements: Collection<E>)

Creates an ArrayList filled from the elements collection.

Properties

size	open val size: Int Returns the size of the collection.

Inherited Properties

modCount

var modCount: Int

Functions

add	open fun add(element: E): Boolean Adds the specified element to the collection. open fun add(index: Int, element: E) Inserts an element into the list at the specified index.
addAll	open fun addAll(elements: Collection<E>): Boolean Adds all of the elements in the specified collection to this collection. open fun addAll(index: Int, elements: Collection<E>): Boolean Inserts all of the elements in the specified collection elements into this list at the specified index.
clear	open fun clear() Removes all elements from this collection.
ensureCapacity	fun ensureCapacity(minCapacity: Int) Does nothing in this ArrayList implementation.
get	open fun get(index: Int): E Returns the element at the specified index in the list.
indexOf	open fun indexOf(element: E): Int Returns the index of the first occurrence of the specified element in the list, or -1 if the specified element is not contained in the list.
lastIndexOf	open fun lastIndexOf(element: E): Int Returns the index of the last occurrence of the specified element in the list, or -1 if the specified element is not contained in the list.
remove	open fun remove(element: E): Boolean Removes a single instance of the specified element from this collection, if it is present.
removeAt	open fun removeAt(index: Int): E Removes an element at the specified index from the list.
removeRange	open fun removeRange(fromIndex: Int, toIndex: Int) Removes the range of elements from this list starting from fromIndex and ending with but not including toIndex.
set	open fun set(index: Int, element: E): E Replaces the element at the specified position in this list with the specified element.
toArray	open fun toArray(): Array<Any?> Returns new array of type `Array<Any?>` with the elements of this collection.
toString	open fun toString(): String Returns a string representation of the object.
trimToSize	fun trimToSize() Does nothing in this ArrayList implementation.

Inherited Functions

equals	open fun equals(other: Any?): Boolean Compares this list with another list instance with the ordered structural equality.
hashCode	open fun hashCode(): Int Returns the hash code value for this list.
iterator	open fun iterator(): MutableIterator<E> Returns an iterator over the elements of this object.
listIterator	open fun listIterator(index: Int): MutableListIterator<E> Returns a list iterator over the elements in this list (in proper sequence), starting at the specified index. open fun listIterator(): MutableListIterator<E> Returns a list iterator over the elements in this list (in proper sequence).
subList	open fun subList( fromIndex: Int, toIndex: Int ): MutableList<E> Returns a view of the portion of this list between the specified fromIndex (inclusive) and toIndex (exclusive). The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa.
