any method
- @override
Checks whether test
accepts any element provided by this stream.
Calls test
on each element of the stream.
If the call returns true
, the returned future is completed with true
and processing stops.
If the stream ends without finding an element that test
accepts,
the returned future is completed with false
.
If this stream contains an error, or if the call to test
throws,
the returned future is completed with that error, and processing stops.
Implementation
@override
AsObservableFuture<bool> any(bool test(T element)) =>
new AsObservableFuture<bool>(stream.any(test));
