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 {@link KeyValueDiffer} available.

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