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. Bear in mind that Sets require immutable objects to function correctly.
The {@link org.apache.commons.collections4.set.ListOrderedSet ListOrderedSet}class provides an alternative approach, by wrapping an existing Set and retaining insertion order in the iterator.
This class is Serializable from Commons Collections 3.1. @since 3.0 @version $Id: SetUniqueList.java 1479405 2013-05-05 21:58:52Z tn $
