Method Detail

zipAndConcat

@SafeVarargs
public static <T> Iterable<T> zipAndConcat(Iterable<T>... inputs)

Combine the given iterables by peeling off items one at a time from each of the input iterables until any one of the iterables are exhausted.

forEachPair

public static <L,R> void forEachPair(Iterable<L> left,
                                     Iterable<R> right,
                                     java.util.function.BiConsumer<? super L,? super R> consumer)

Provides convenient consumption of a pair of Iterables of the same length.

dedupKeepLast

public static <T> Set<T> dedupKeepLast(Iterable<T> toDedup)

Returns a deduped version of toDedup and keeps the order of elements If a key is contained more than once (that is, there are multiple elements e1, e2... en, such that ei.equals(ej)) then the last one will be kept in the ordering

enumerate

public static <T> Iterable<Pair<Integer,T>> enumerate(Iterable<T> items)

Returns:

a new Iterable containing pairs of the original items along with the index of the current item.
