CollectionUtil and ListUtil

CollectionUtil

Located at dev.anvilcraft.lib.v2.util.CollectionUtil, provides collection operations:

• allMatch(Collection<T>, Predicate<T>) – matches all elements
• anyMatch(Collection<T>, Predicate<T>) – matches any element
• newMultimap(M, Collection<V>, Function<V,K>) – creates a Guava Multimap
• newLinkedList(int) – creates a LinkedList (ignores the parameter, for convenience)
• get(SequencedCollection<T>, int) – safely retrieves by index, returns null if out of bounds

ListUtil

Located at dev.anvilcraft.lib.v2.util.ListUtil:

• safelyGet(List<T>, int) – returns Optional<T>, handling empty lists or out-of-bounds access
• cycle(List<T>, int) – cyclically shifts elements, returns a new list
• createWithValues(int, IntFunction<T>) – builds a list of the specified size
• cast(List<T>, Class<R>) – filters and casts to a subtype list
• equals(List<T>, List<U>, BiPredicate<T,U>) – compares two lists using a custom comparator
