npm Package	@angular/core
Module	`import { KeyValueDiffers } from '@angular/core';`
Source	core/src/change_detection/differs/keyvalue_differs.ts

Overview

class KeyValueDiffers {
  constructor(factories: KeyValueDifferFactory[])
  static create<S>(factories: KeyValueDifferFactory[], parent?: KeyValueDiffers): KeyValueDiffers
  static extend<S>(factories: KeyValueDifferFactory[]): Provider
  factories: KeyValueDifferFactory[]
  find(kv: any): KeyValueDifferFactory
}

Description

A repository of different Map diffing strategies used by NgClass, NgStyle, and others.

Static Members

`static create<S>(factories: KeyValueDifferFactory[], parent?: KeyValueDiffers): KeyValueDiffers`

`static extend<S>(factories: KeyValueDifferFactory[]): Provider`

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

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 KeyValueDiffer available.

Example

@Component({
  viewProviders: [
    KeyValueDiffers.extend([new ImmutableMapDiffer()])
  ]
})

Constructor

`constructor(factories: KeyValueDifferFactory[])`

Members

`factories: KeyValueDifferFactory[]`

`find(kv: any): KeyValueDifferFactory`
