Method Detail

filter

FilterableTransformable<T> filter(java.util.function.Predicate<? super T> fn)

Description copied from interface: Filters

Keep only elements for which the supplied predicates hold e.g.

 

     of(1,2,3).filter(i->i>2);

     //[3]

 
 

Specified by:

filter in interface Filters<T>

Parameters:

fn - to filter elements by, retaining matches

Returns:

Filters with elements removed where the predicate does not hold

map

<R> FilterableTransformable<R> map(java.util.function.Function<? super T,? extends R> fn)

Description copied from interface: Transformable

Transform this functor using the supplied transformation function

 


    of(1,2,3).map(i->i*2)

    //[2,4,6]

 
 

Specified by:

map in interface Transformable<T>

Parameters:

fn - Transformation function

Returns:

Transformed Transformable
