All Implemented Interfaces:

Serializable, Cloneable, Iterable<T>, Collection<T>, Set<T>

public class CaseInsensitiveHashSet<T>
extends HashSet<T>

An implementation of Case Insensitive Hash Set with case preservation. Strings are converted to case insensitive strings before being hashed, but original case is preserved. The iterator returns the case preserved Strings that can be casted to a String, no different from an iterator from the standard Hash Set.
