Initializers


init
()

Creates an empty ImmutableArray.


init
(data:ListView<T>)

Creates an ImmutableArray containing all of the elements of data. If you are creating an ImmutableArray from an Array, consider using the [Array.finish] method instead.

Parameters:: data - value of type ListView<T>

Class Methods

@class

method from

(a:Array<T>
):ImmutableArray<T>

Invalidates an Array and returns its contents as an ImmutableArray. This is generally preferable to creating a new instance of ImmutableArray from this array, as finish() does not copy the array's contents. Interacting in any way with an Array after calling this method on it will cause precondition violations (or, if safety checks are disabled, undefined behavior).

Parameters:: a - value of type Array<T>

Instance Methods

-- index operator --
@override

function []

(index:Int
):T

Returns an item from this list.

Parameters:: index - the (zero-based) index of the item to return

Overrides:: frost.collections.ListView.[]
