Type Members

1. class BooleanSerializer extends QueueSerializer[Boolean]

   

2. class BroadcastBuffer[T] extends BroadcastBufferBase[T, T]

   

   Fan-out the stream to several streams emitting each incoming upstream element to all downstream consumers.

   Fan-out the stream to several streams emitting each incoming upstream element to all downstream consumers.

   Emits when one of the inputs has an element available

   Does not back-pressure upstream when downstream back-pressures, instead buffers the stream element to memory mapped queue

   Completes when upstream completes and all downstream finish consuming stream elements

   Cancels when downstream cancels

3. class BroadcastBufferAtLeastOnce[T] extends BroadcastBufferBase[T, Event[T]]

   

   Fan-out the stream to several streams emitting each incoming upstream element to all downstream consumers.

   Fan-out the stream to several streams emitting each incoming upstream element to all downstream consumers.

   Emits when one of the inputs has an element available

   Does not back-pressure upstream when downstream back-pressures, instead buffers the stream element to memory mapped queue

   Completes when upstream completes and all downstream finish consuming stream elements

   Cancels when downstream cancels

   A commit guarantee can be ensured to avoid data lost while consuming stream elements by adding a commit stage after downstream consumer.
