Stable Class

Class Overview

class KeyValueDiffers {
  staticcreate(factories: KeyValueDifferFactory[], parent?: KeyValueDiffers) : KeyValueDiffers

  constructor(factories: KeyValueDifferFactory[])

  find(kv: Object) : KeyValueDifferFactory
}

Class Description

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

Constructor

constructor(factories: KeyValueDifferFactory[])

Static Members

create(factories: KeyValueDifferFactory[], parent?: KeyValueDiffers) : KeyValueDiffers
extend(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.

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