    Methods in org.apache.commons.collections4 with parameters of type Equator
    Modifier and Type | Method and Description
    --- | ---
    `static <E> boolean` | IterableUtils.`contains(Iterable<? extends E> iterable, E object, Equator<? super E> equator)` Checks if the object is contained in the given iterable.
    `static <E> boolean` | CollectionUtils.`isEqualCollection(Collection<? extends E> a, Collection<? extends E> b, Equator<? super E> equator)` Returns `true` iff the given `Collection`s contain exactly the same elements with exactly the same cardinalities.
    `static <E> List<E>` | ListUtils.`longestCommonSubsequence(List<E> a, List<E> b, Equator<? super E> equator)` Returns the longest common subsequence (LCS) of two sequences (lists).
    `static <E> Collection<E>` | CollectionUtils.`removeAll(Iterable<E> collection, Iterable<? extends E> remove, Equator<? super E> equator)` Removes all elements in `remove` from `collection`.
    `static <E> Collection<E>` | CollectionUtils.`retainAll(Iterable<E> collection, Iterable<? extends E> retain, Equator<? super E> equator)` Returns a collection containing all the elements in `collection` that are also in `retain`.
