flatMap

public <T,R> Higher<CRE,R> flatMap(java.util.function.Function<? super T,? extends Higher<CRE,R>> fn,
                                   Higher<CRE,T> ds)

Specified by:

flatMap in interface Monad<CRE>

unit

public <T> Higher<CRE,T> unit(T value)

Description copied from interface: Pure

Create a new instance of the core type (e.g. a List or CompletableFuture) that is HKT encoded

Specified by:

unit in interface Pure<CRE>

Parameters:

value - To populate new instance of

Returns:

HKT encoded new instance with supplied value

map

public <T,R> Higher<CRE,R> map(java.util.function.Function<? super T,? extends R> fn,
                               Higher<CRE,T> ds)

Description copied from interface: Functor

Transform the supplied data structure using the supplied transformation function

  
  ListX<Integer> listx = ListX.of(1,2,3);
        ListType<Integer> mapped1 =Lists.functor().map(a->a+1, ListType.widen(listx));
        mapped1.add(1);
        ListX<Integer> listxMapped = mapped1.list();
 
 

Specified by:

map in interface Functor<CRE>

Parameters:

fn - Transformation function

ds - Datastructure to transform

Returns:

ap
