| 30 | * `ofType` filters an Observable of `Actions` into an Observable of the actions
|
| 31 | * whose type strings are passed to it.
|
| 32 | *
|
| 33 | * For example, if `actions` has type `Actions<AdditionAction|SubstractionAction>`, and
|
| 34 | * the type of the `Addition` action is `add`, then
|
| 35 | * `actions.pipe(ofType('add'))` returns an `Observable<AdditionAction>`.
|
| 36 | *
|
| 37 | * Properly typing this function is hard and requires some advanced TS tricks
|
| 38 | * below.
|
| 39 | *
|
| 40 | * Type narrowing automatically works, as long as your `actions` object
|
| 41 | * starts with a `Actions<SomeUnionOfActions>` instead of generic `Actions`.
|
| 42 | *
|
| 43 | * For backwards compatibility, when one passes a single type argument
|
| 44 | * `ofType<T>('something')` the result is an `Observable<T>`. Note, that `T`
|
| 45 | * completely overrides any possible inference from 'something'.
|
| 46 | *
|
| 47 | * Unfortunately, for unknown 'actions: Actions' these types will produce
|
| 48 | * 'Observable<never>'. In such cases one has to manually set the generic type
|
| 49 | * like `actions.ofType<AdditionAction>('add')`.
