Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Transformable<T>

An interface that represents a type that can transform a value from one type to another

Method Summary

Modifier and Type	Method and Description
<R> Transformable<R>	map(java.util.function.Function<? super T,? extends R> fn) Transform this functor using the supplied transformation function
default Transformable<T>	peek(java.util.function.Consumer<? super T> c) Peek at the current value of this Transformable, without transforming it

Method Detail

map

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

Transform this functor using the supplied transformation function

 


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

    //[2,4,6]

 
 

Parameters:

fn - Transformation function

Returns:

Transformed Transformable

peek

default Transformable<T> peek(java.util.function.Consumer<? super T> c)

Peek at the current value of this Transformable, without transforming it

 


    of(1,2,3).map(System.out::println)

    1
    2
    3

 
 

Parameters:

c - Consumer that recieves each element from this Transformable

Returns:

Transformable that will peek at each value
