                                   Function<I,V> transformer)

entry

public static <K,I,V> Map.Entry<K,V> entry(Map.Entry<? extends K,? extends I> entry,
                                           Function<I,V> transformer)

set

public static <I,E> Set<E> set(Set<I> set,
                               Function<I,E> transformer)

list

public static <I,E> List<E> list(List<I> set,
                                 Function<I,E> transformer)

collection

public static <I,E> Collection<E> collection(Collection<? extends I> collection,
                                             Function<I,E> transformer)

enclosedIterable

public static <I,E> EnclosedIterable<E> enclosedIterable(EnclosedIterable<I> iterable,
                                                         Function<I,E> transformer)

iterator

public static <I,E> Iterator<E> iterator(Iterator<? extends I> set,
                                         Function<I,E> transformer)

Iterator that transforms its values from one type to another using the supplied Function. This iterator's Iterator.remove() method delegates to the supplied iterator.
