Class While<A extends Actor>

  • All Implemented Interfaces:
    Action<A>
    public final class While<A extends Actor>
extends java.lang.Object
implements Action<A>
    Executes action repeatedly while the predicate is true. When the predicate changes from true to false, the currently executed action continues until it finishes and then the While action finishes as well. It will not be executed again even if the predicate becomes true again.

    The constructor expects either a predicate that accepts While action as a parameter, or a parameter-less predicate.
