List to ensure that no duplicates are present much like a Set. The List interface makes certain assumptions/requirements. This implementation breaks these in certain ways, but this is merely the result of rejecting duplicates. Each violation is explained in the method, but it should not affect you.
The {@link org.apache.commons.collections.set.ListOrderedSet ListOrderedSet}class provides an alternative approach, by wrapping an existing Set and retaining insertion order in the iterator.
