- java.util.AbstractCollection<E>
- - java.util.AbstractSet<E>
  - - java.util.HashSet<T>
    - - org.apache.catalina.util.ResourceSet<T>

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<T>, java.util.Collection<T>, java.util.Set<T>
```
public final class ResourceSet<T>
extends java.util.HashSet<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.
