    Method
    Description
    static <T> Set<T>
    asSet(Iterable<T> c)
    If the argument is already an instance of a set then cast it to a set and return it; otherwise create a new LinkedHashSet initialized with the given items
    static <K, V> Set<V>
    mapSet(Set<K> set, Map<K,V> map)
    Short hand for Set result = source.stream().map(fn).collect(Collectors.toSet()) Maps a set of keys to a corresponding set of values via a given map TODO Probably this method can be replaced by something from guava
    static <T> Set<T>
    newForwardingSet(Supplier<? extends Set<T>> setSupplier)
