---|---|---|---|---|---|---|
static create<S>(factories: KeyValueDifferFactory[], parent?: KeyValueDiffers): KeyValueDiffersParameters
Returns

extend() | |||
---|---|---|---|
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. | |||
static extend<S>(factories: KeyValueDifferFactory[]): StaticProviderParameters
Returns
| |||
Usage NotesExampleThe 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.
