Class CaseInsensitiveSet<E>

java.lang.Object

com.cedarsoftware.util.CaseInsensitiveSet<E>

All Implemented Interfaces:

Iterable<E>, Collection<E>, Set<E>

public class CaseInsensitiveSet<E>
extends Object
implements Set<E>

Implements a java.util.Set that will not utilize 'case' when comparing Strings contained within the Set. The set can be homogeneous or heterogeneous. If the CaseInsensitiveSet is iterated, when Strings are encountered, the original Strings are returned (retains case).
