Description
Add a method to MethodHandles, like:
public static MethodHandle dropReturn(MethodHandle target)
That can be used to drop the return value of a MethodHandle.
Doing this is currently already possible with the following code:
MethodHandle target = ...;
Class<?> targetReturnType = target.type().returnType();
if (targetReturnType == void.class)
return target;
return filterReturnValue(target, empty(methodType(void.class, targetReturnType)));
But, a combinator can be provided as a short-hand.
