final class AtomicAny[A <: AnyRef] extends Atomic[A]

Atomic references wrapping AnyRef values.

A

is forced to be an AnyRef because the equality test is by reference and not by value.

  8. def compareAndSet(expect: A, update: A): Boolean

    Does a compare-and-set operation on the current value.

    Does a compare-and-set operation on the current value. For more info, checkout the related Compare-and-swap Wikipedia page.

    It's an atomic, worry free operation.

    expect

    is the value you expect to be persisted when the operation happens

    update

    will be the new value, should the check for expect succeeds

    returns

    either true in case the operation succeeded or false otherwise

  14. final macro def getAndTransform(cb: (A) ⇒ A): A

    Abstracts over compareAndSet.

    Abstracts over compareAndSet. You specify a transformation by specifying a callback to be executed, a callback that transforms the current value. This method will loop until it will succeed in replacing the current value with the one produced by the given callback.

    Note that the callback will be executed on each iteration of the loop, so it can be called multiple times - don't do destructive I/O or operations that mutate global state in it.

    cb

    is a callback that receives the current value as input and returns the update which is the new value that should be persisted

    returns

    the old value, just prior to when the successful update happened

    cb

    is a callback that receives the current value as input and returns a tuple that specifies the update + what should this method return when the operation succeeds.

    returns

    whatever was specified by your callback, once the operation succeeds
