Method Detail

reduceMOptional

AnyM<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)];
		

Parameters:

reducer - An identity value (approx. a seed) and BiFunction with a single type to reduce this anyM

Returns:

Reduced AnyM

reduceMStream

AnyM<T> reduceMStream(Monoid<java.util.stream.Stream<T>> reducer)

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

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

Parameters:

reducer - An identity value (approx. a seed) and BiFunction with a single type to reduce this anyM

Returns:

Reduced AnyM

reduceMStreamable

AnyM<T> reduceMStreamable(Monoid<Streamable<T>> reducer)

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

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

Parameters:

reducer - An identity value (approx. a seed) and BiFunction with a single type to reduce this anyM

Returns:

Reduced AnyM

reduceMIterable

AnyM<T> reduceMIterable(Monoid<java.lang.Iterable<T>> reducer)

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

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

Parameters:

reducer - An identity value (approx. a seed) and BiFunction with a single type to reduce this anyM

Returns:

Reduced AnyM

reduceMCompletableFuture

AnyM<T> reduceMCompletableFuture(Monoid<java.util.concurrent.CompletableFuture<T>> reducer)

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

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

Parameters:

reducer - An identity value (approx. a seed) and BiFunction with a single type to reduce this anyM

Returns:

Reduced AnyM
