    A small toolkit of classes that support compare-and-swap semantics for safe mutation of variables.

    A small toolkit of classes that support compare-and-swap semantics for safe mutation of variables.

    On top of the JVM, this means dealing with lock-free thread-safe programming. Also works on top of Javascript, with Scala.js, for API compatibility purposes and because it's a useful way to box a value.

    The backbone of Atomic references is this method:

    def compareAndSet(expect: T, update: T): Boolean

    This method atomically sets a variable to the update value if it currently holds the expect value, reporting true on success or false on failure. The classes in this package also contain methods to get and unconditionally set values.

    Building a reference is easy with the provided constructor, which will automatically return the most specific type needed (in the following sample, that's an AtomicDouble, inheriting from AtomicNumber[A]):

    val atomicNumber = Atomic(12.2)

atomicNumber.incrementAndGet()
// => 13.2

    These also provide useful helpers for atomically mutating of values (i.e. transform, transformAndGet, getAndTransform, etc...) or of numbers of any kind (incrementAndGet, getAndAdd, etc...).

  • package cancelables

    Cancelables represent asynchronous units of work or other things scheduled for execution and whose execution can be canceled.

    Cancelables represent asynchronous units of work or other things scheduled for execution and whose execution can be canceled.

    One use-case is the scheduling done by monix.execution.Scheduler, in which the scheduling methods return a Cancelable, allowing the canceling of the scheduling.

    Example:

    val s = ConcurrentScheduler()
val task = s.scheduleRepeated(10.seconds, 50.seconds, {
  doSomething()
})

// later, cancels the scheduling ...
task.cancel()

    Builds a limited capacity and back-pressured AsyncQueue.

    capacity

    is the maximum capacity of the internal buffer; note that due to performance optimizations, the actual capacity gets rounded to a power of 2, so the actual capacity may be slightly different than the one specified

    s

    is a Scheduler, needed for asynchronous waiting on poll when the queue is empty or for back-pressuring offer when the queue is full

    Builds an unlimited AsyncQueue that can use the entire memory available to the process.

    chunkSizeHint

    is an optimization parameter — the underlying implementation may use an internal buffer that uses linked arrays, in which case the "chunk size" represents the size of a chunk; providing it is just a hint, it may or may not be used

    s

    is a Scheduler, needed for asynchronous waiting on poll when the queue is empty or for back-pressuring offer when the queue is full

    Builds an AsyncQueue with fine-tuned config parameters.

    This is unsafe due to problems that can happen via selecting the wrong ChannelType, so use with care.

    capacity

    specifies the BufferCapacity, which can be either "bounded" (with a maximum capacity), or "unbounded"

    channelType

    (UNSAFE) specifies the concurrency scenario, for fine tuning the performance
