IterableDiffers

class

A repository of different iterable diffing strategies used by NgFor, NgClass, and others.

class IterableDiffers {
  static create(factories: IterableDifferFactory[], parent?: IterableDiffers): IterableDiffers
  static extend(factories: IterableDifferFactory[]): StaticProvider
  constructor(factories: IterableDifferFactory[])
  factories: IterableDifferFactory[]
  find(iterable: any): IterableDifferFactory
}

Static methods

create()

`static create(factories: IterableDifferFactory[], parent?: IterableDiffers): IterableDiffers`

Parameters

`factories`	`IterableDifferFactory[]`
`parent`	`IterableDiffers`	Optional. Default is `undefined`.

Returns

IterableDiffers

extend()

Takes an array of IterableDifferFactory and returns a provider used to extend the inherited IterableDiffers instance with the provided factories and return a new IterableDiffers instance.

`static extend(factories: IterableDifferFactory[]): StaticProvider`

Parameters

factories IterableDifferFactory[]

Returns

StaticProvider

Usage Notes

Example

The following example shows how to extend an existing list of factories, which will only be applied to the injector for this component and its children. This step is all that's required to make a new IterableDiffer available.

@Component({
  viewProviders: [
    IterableDiffers.extend([new ImmutableListDiffer()])
  ]
})

Constructor

`constructor(factories: IterableDifferFactory[])`

Parameters

factories IterableDifferFactory[]

Properties

Property	Description
`factories: IterableDifferFactory[]`

Methods

find()

`find(iterable: any): IterableDifferFactory`

Parameters

iterable any

Returns

IterableDifferFactory
