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
