Inserts all elements in the specified collection into this list, starting at the specified position. Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices). The new elements will appear in the list in the order that they are returned by the specified collection's iterator.

addListener

fun addListener(listener: ValueObserver<List<T>>)

Adds a listener silently.

addListenerAndInvoke

fun addListenerAndInvoke(initialValue: List<T>, listener: (List<T>, List<T>) -> Unit)

Adds a listener and calls ValueObserver.update on this new listener with given initial value.

clear

fun clear()

Removes all elements from this list. The list will be empty after this call returns.

clearListeners

fun clearListeners()

Removes all listeners.

contains

operator fun contains(o: Any?): Boolean

Returns true if this list contains the specified element.

forEach

open fun forEach(p0: Consumer<in T>)

get

operator fun get(index: Int): T

Returns the element at the specified position in this list.

getOrNull

fun getOrNull(index: Int): T?

May return the element at the specified position in this list or null.

indexOf

fun indexOf(o: Any?): Int

Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.

isEmpty

fun isEmpty(): Boolean

Returns true if this list contains no elements.

isNotEmpty

fun isNotEmpty(): Boolean

Returns true if this list contains elements.

iterator

open operator override fun iterator(): Iterator<T>

Returns an Iterator over the elements in this ReadonlyObservableList.

lastIndexOf

fun lastIndexOf(o: Any?): Int

Returns the index of the last occurrence of the specified element in this list, or -1 if this list does not contain the element.

remove

fun remove(o: T): Boolean

Removes the first occurrence of the specified element from this list, if it is present.

removeAll

fun removeAll(elements: Collection<*>): Boolean

Removes from this list all of its elements that are contained in the specified collection.

removeAt

fun removeAt(index: Int): T

Removes an element at the specified index from the list.

removeFirst

fun removeFirst(): T

Removes the first element from this list and returns that removed element.

removeFirstOrNull

fun removeFirstOrNull(): T?

Removes the first element from this list and returns that removed element, or returns null if this list is empty.

removeIf

fun removeIf(filter: Predicate<in T>): Boolean

Removes all elements of this collection that satisfy the given predicate.

removeLast

fun removeLast(): T

Removes the last element from this list and returns that removed element.

removeLastOrNull

fun removeLastOrNull(): T?

Removes the last element from this list and returns that removed element, or returns null if this list is empty.

removeListener

fun removeListener(listener: ValueObserver<List<T>>): Boolean

Removes a listener.

removeSilent

fun removeSilent(o: T): Boolean

removes o from the ObservableList silently.

replaceAll

fun replaceAll(operator: UnaryOperator<T>)

Replaces each element of this list with the result of applying the operator to that element.

retainAll

fun retainAll(elements: Collection<*>): Boolean

Retains only the elements in this list that are contained in the specified collection.

set

operator fun set(index: Int, element: T): T

Replaces the element at the specified position in this list with the specified element.

setAll

fun setAll(elements: Collection<T>): Boolean

Sets all elements in the specified collection as the new contents of this list, in the order that they are returned by the specified collection's Iterator. Clears all items currently in this list.

sort

fun sort(comparator: Comparator<in T>)

Sorts this list by given comparator.

spliterator

override fun spliterator(): Spliterator<T>

Creates a fail-fastSpliterator over the elements in this list.

subList

fun subList(fromIndex: Int, toIndex: Int): List<T>

Returns a view of the portion of this list between the specified fromIndex inclusive and toIndex exclusive. (If fromIndex and toIndex are equal, the returned list is empty.)

Properties

indices

val indices: IntRange

All available indices of this list as IntRange i.e. 0..size()-1.

size

val size: Int

Returns the number of elements in this list.
