Abstract Value Members
- abstract 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
expectsucceeds- returns
either true in case the operation succeeded or false otherwise
- abstract def get(): A
Get the current value persisted by this Atomic.
- abstract def getAndSet(update: A): A
Sets the persisted value to
updateand returns the old value that was in place.Sets the persisted value to
updateand returns the old value that was in place. It's an atomic, worry free operation. - abstract def lazySet(update: A): Unit
Eventually sets to the given value.
Eventually sets to the given value. Has weaker visibility guarantees than the normal
set(). - abstract def set(update: A): Unit
Updates the current value.
Updates the current value.
- update
will be the new value returned by
get()

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
updatewhich is the new value that should be persisted- returns
the old value, just prior to when the successful update happened

Package Overview
monix.execution exposes lower level primitives for dealing with asynchronous execution:
Atomictypes, as alternative tojava.util.concurrent.atomicmonix.catnap exposes pure abstractions built on top of the Cats-Effect type classes:
monix.eval is for dealing with evaluation of results, thus exposing Task and Coeval.
monix.reactive exposes the
Observablepattern:Observableimplementationsmonix.tail exposes Iterant for purely functional pull based streaming:
BatchandBatchCursor, the alternatives to Scala'sIterableandIteratorrespectively that we are using within Iterant's encodingYou can control evaluation with type you choose - be it Task, Coeval, cats.effect.IO or your own as long as you provide correct cats-effect or cats typeclass instance.
