Method Detail

asList

public static <E> java.util.List<E> asList(java.lang.Iterable<E> i)

Turns the iterable into a list.

cast

public static <E> java.lang.Iterable<E> cast(java.lang.Iterable i)

Turns an iterable into its type-safe cousin.

singleton

public static <E> java.lang.Iterable<E> singleton(E single)

An iterable containing a single element.

map

public static <F,T> java.lang.Iterable<T> map(java.lang.Iterable<F> from,
                                                    Mapper<? super F,T> mapper)

Create a new iterable by applying a mapper function to each element of a given sequence.

filter

public static <T> java.lang.Iterable<T> filter(java.lang.Iterable<T> sequence,
                                               Predicate<? super T> filter)

Exclude all elements from an iterable that don't match a given predicate.

count

public static int count(java.lang.Iterable seq)

Count the number of elements in a sequence.

any

public static <T> boolean any(java.lang.Iterable<T> sequence,
                              Predicate<? super T> predicate)

Determines whether a given predicate holds true for at least one element.

Returns false for an empty sequence.

all

public static <T> boolean all(java.lang.Iterable<T> sequence,
                              Predicate<? super T> predicate)
