react.UnitSlot

All Implemented Interfaces:

Runnable, Reactor.RListener, SignalView.Listener<Object>, ValueView.Listener<Object>

public abstract class UnitSlot
extends Slot<Object>
implements Runnable

A Slot for use when the type of emitted signal is ignored. As slots are contravariant, this slot may be wired to any signal without bothering to determine its type. Instances of this class also implement Runnable so that they may be invoked by code that expects runnables rather than no-arg slots.
