scalax.concurrent.cancelables

SingleAssignmentCancelable

final class SingleAssignmentCancelable extends AssignableCancelable

Represents a scalax.concurrent.Cancelable that can be assigned only once to another cancelable reference.

Similar to scalax.concurrent.cancelables.MultiAssignmentCancelable, except that in case of multi-assignment, it throws a java.lang.IllegalStateException.

If the assignment happens after this cancelable has been canceled, then on assignment the reference will get canceled too.

Useful in case you need a forward reference.

    Sets the underlying cancelable reference with s.

    In case this SingleAssignmentCancelable is already canceled, then the reference value will also be canceled on assignment.

    Throws IllegalStateException in case this cancelable has already been assigned.

  8. def cancel(): Boolean

    Cancels the unit of work represented by this reference.

    Cancels the unit of work represented by this reference.

    Guaranteed idempotency - calling it multiple times should have the same side-effect as calling it only a single time. Implementations of this method should also be thread-safe.

    returns

    true if cancellation happened, or false if another execution happened previously or concurrently.
