# bind method

Stream<String> bind(

1. Stream<String> stream

)
override

Transforms the provided `stream`.

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

The StreamTransformer interface is completely generic, so it cannot say what subclasses do. Each StreamTransformer should document clearly how it transforms the stream (on the class or variable used to access the transformer), as well as any differences from the following typical 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.

Transformers are free to handle errors in any way. A transformer implementation may choose to propagate errors, or convert them to other events, or ignore them completely, but if errors are ignored, it should be documented explicitly.

## Implementation

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