public class CaseInsensitiveSet extends SetDecorator<String>
iterator() method for example returns the originally values.
Note: The behavior of this class is undefined when wrapping a set that has keys that would result in duplicate case-insensitive values.
set| Constructor and Description |

CaseInsensitiveSet()
Constructs a new empty case-insensitive set.
|
CaseInsensitiveSet(Collection<String> c)
Constructs a new case-insensitive set containing the elements in the specified
collection.
|
CaseInsensitiveSet(int initialCapacity)
Constructs a new, empty case-insensitive set; the backing
HashSet instance has
the specified initial capacity and default load factor. |
CaseInsensitiveSet(int initialCapacity,
float loadFactor)
Constructs a new, empty case-insensitive set; the backing
HashSet instance has
the specified initial capacity and the specified load factor. |
