    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[T]):

    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...).

    Constructs an AtomicShort reference, applying the provided PaddingStrategy in order to counter the "false sharing" problem.

    Note that for Scala.js we aren't applying any padding, as it doesn't make much sense, since Javascript execution is single threaded, but this builder is provided for syntax compatibility anyway across the JVM and Javascript and we never know how Javascript engines will evolve.
