Ref

implicit abstract val F: Async[F]

abstract def access: F[(A, (Attempt[A]) ⇒ F[Boolean])]

Obtain a snapshot of the current value of the Ref, and a setter for updating the value.

abstract def cancellableGet: F[(F[A], F[Unit])]

Like get, but returns an F[Unit] that can be used cancel the subscription.

abstract def set(a: F[A]): F[Unit]

Asynchronously set a reference.

final def !=(arg0: Any): Boolean

final def ##(): Int

def +(other: String): String

def ->[B](y: B): (Ref[F, A], B)

final def ==(arg0: Any): Boolean

final def asInstanceOf[T0]: T0

def clone(): AnyRef

def ensuring(cond: (Ref[F, A]) ⇒ Boolean, msg: ⇒ Any): Ref[F, A]

def ensuring(cond: (Ref[F, A]) ⇒ Boolean): Ref[F, A]

def ensuring(cond: Boolean, msg: ⇒ Any): Ref[F, A]

def ensuring(cond: Boolean): Ref[F, A]

final def eq(arg0: AnyRef): Boolean

def equals(arg0: Any): Boolean

def finalize(): Unit

def formatted(fmtstr: String): String

def get: F[A]

Obtain the value of the Ref, or wait until it has been set.

final def getClass(): Class[_]

def hashCode(): Int

final def isInstanceOf[T0]: Boolean

def modify(f: (A) ⇒ A): F[Change[A]]

Repeatedly invoke tryModify(f) until it succeeds.

def modify2[B](f: (A) ⇒ (A, B)): F[(Change[A], B)]

Like modify, but allows to extra b in single step.

final def ne(arg0: AnyRef): Boolean

final def notify(): Unit

final def notifyAll(): Unit

def setPure(a: A): F[Unit]

Asynchronously set a reference to a pure value.

final def synchronized[T0](arg0: ⇒ T0): T0

def toString(): String

def tryModify(f: (A) ⇒ A): F[Option[Change[A]]]

Try modifying the reference once, returning None if another concurrent set or modify completes between the time the variable is read and the time it is set.

def tryModify2[B](f: (A) ⇒ (A, B)): F[Option[(Change[A], B)]]

Like tryModify but allows to return B along with change.

final def wait(): Unit

final def wait(arg0: Long, arg1: Int): Unit

final def wait(arg0: Long): Unit

def →[B](y: B): (Ref[F, A], B)
