IterableDiffers

Stable Class

Class Overview

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

Class Description

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

Constructor

constructor(factories: IterableDifferFactory[])

Static Members

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

extend(factories: IterableDifferFactory[]) : Provider

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.

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()])
  ]
})
