PushStreamWithValue<T> class

StreamWithValue implementation that creates a Stream from subsequent calls to add. This way, value is always set to the latest value that has been added, regardless of whether the updates are listened to (in contrast to StreamWithLatestValue).

Implemented types

• StreamWithValue<T>
• EventSink<T>

Available Extensions
