Examples of org.apache.cocoon.util.location.Location

org.apache.cocoon.util.location.Location
A location in a resource. The location is composed of the URI of the resource, and the line and column numbers within that resource (when available), along with a description.
Locations are mostly provided by {@link Locatable}s objects. @since 2.1.8 @version $Id: Location.java 587751 2007-10-24 02:41:36Z vgritsenko $
