Class ResourceSet<T>
java.lang.Object
java.util.AbstractCollection<T>
java.util.AbstractSet<T>
java.util.HashSet<T>
org.apache.catalina.util.ResourceSet<T>
- Type Parameters:
- T- The type of elements in the Set
- All Implemented Interfaces:
- Serializable,- Cloneable,- Iterable<T>,- Collection<T>,- Set<T>
Extended implementation of HashSet that includes a 
locked property. This class can be
 used to safely expose resource path sets to user classes without having to clone them in order to avoid
 modifications. When first created, a ResourceMap is not locked.- Author:
