# bind method

Stream<String> bind (Stream<String> stream)

Transforms the provided `stream`.

Returns a new stream with events that are computed from events of the provided `stream`.

Implementors of the StreamTransformer interface should document differences from the following expected behavior:

- When the returned stream is listened to, it starts listening to the input `stream`.
- Subscriptions of the returned stream forward (in a reasonable time) a StreamSubscription.pause call to the subscription of the input `stream`.
- Similarly, canceling a subscription of the returned stream eventually (in reasonable time) cancels the subscription of the input `stream`.

"Reasonable time" depends on the transformer and stream. Some transformers, like a "timeout" transformer, might make these operations depend on a duration. Others might not delay them at all, or just by a microtask.

## Implementation

    Stream<String> bind(Stream<String> stream) {
      return new Stream<String>.eventTransformed(
          stream, (EventSink<String> sink) => new _LineSplitterEventSink(sink));
    }
