| * This interface is implemented by objects that visit resource trees. The fast |

| * number of objects. The visitor is provided with a callback interface, |
| * instead of a resource. Through the callback, the visitor can request |
| * information about the resource being visited. |
| * <p> |
| * Usage: |
| * <pre> |
| * class Visitor implements IResourceProxyVisitor { |
| * public boolean visit (IResourceProxy proxy) { |
| * // your code here |
| * return true; |
| * } |
| * } |
