Class MutableArray

public

This mixin defines the API for modifying array-like objects. These methods can be applied only to a collection that keeps its items in an ordered set. It builds upon the Array mixin and adds methods to modify the array. One concrete implementations of this class include ArrayProxy.

It is important to use the methods in this class to modify arrays so that changes are observable. This allows the binding system in Ember to function correctly.

Note that an Array can change even if it does not implement this mixin. For example, one might implement a SparseArray that cannot be directly modified, but if its underlying enumerable changes, it will change also.

Show:

Module: @ember/array
returns
this

This is the handler for the special array content property. If you get this property, it will return this. If you set this property to a new array, it will replace the current content.

Module: @ember/array
returns
Object | undefined
The first object in the array

The first object in the array, or undefined if the array is empty.

Module: @ember/array

Becomes true whenever the array currently has observers watching changes on the array.

Module: @ember/array
returns
Object | undefined
The last object in the array

The last object in the array, or undefined if the array is empty.

Module: @ember/array

Required. You must implement this method to apply this mixin.

Your array must support the length property. Your replace methods should set this property whenever it changes.
