Class UnitMatch<I>

java.lang.Object
  akka.japi.pf.UnitMatch<I>

Type Parameters:

I - the input type, that this PartialFunction will be applied to This is an EXPERIMENTAL feature and is subject to change until it has received more real world testing.

public class UnitMatch<I>
extends java.lang.Object

Version of PartialFunction that can be built during runtime from Java. This is a specialized version of UnitMatch to map java void methods to BoxedUnit.
