Method Detail

reduceMOptional

AnyMValue<T> reduceMOptional(Monoid<java.util.Optional<T>> reducer)

Perform a reduction where NT is a (native) Monad type e.g.

 
   Monoid<Optional<Integer>> optionalAdd = Monoid.of(Optional.of(0), (a,b)-> Optional.of(a.get()+b.get()));
		
		AnyM.fromStream(Stream.of(2,8,3,1)).reduceM(optionalAdd);
		
		//AnyM[Optional(14)];
