Asynchronous queue interface.
An asynchronous semaphore, useful as a concurrency primitive.
A signal whose value may be set asynchronously.
A signal whose value may be set asynchronously. Provides continuous and discrete streams for responding to changes to it's value.
Asynchronous Topic.
Asynchronous Topic.
Topic allows you to distribute A
published by arbitrary number of publishers to arbitrary number of subscribers.
Topic has built-in back-pressure support implemented as maximum bound (maxQueued
) that a subscriber is allowed to enqueue.
Once that bound is hit, publishing may semantically block until the lagging subscriber consumes some of its queued elements.
Additionally the subscriber has possibility to terminate whenever size of enqueued elements is over certain size
by using subscribeSize
.
Asynchronous queue interface. Operations are all nonblocking in their implementations, but may be 'semantically' blocking. For instance, a queue may have a bound on its size, in which case enqueuing may block until there is an offsetting dequeue.
