Examples of SourceResolver

org.apache.cocoon.environment.SourceResolver
Base interface for resolving a source by system identifiers. This component is a special extension of the Avalon Excalibur {@link org.apache.excalibur.source.SourceResolver} that is onlyused for Cocoon sitemap components. It extends the source resolver with simple to use source to SAX conversion methods. @author Carsten Ziegeler @version CVS $Id: SourceResolver.java,v 1.1 2003/03/09 00:09:28 pier Exp $
org.apache.excalibur.source.SourceResolver
Base interface for resolving a source by system identifiers. Instead of using the java.net.URL classes which prevent you from adding your own custom protocols in a server environment, you should use this resolver for all URLs. The resolver creates for each source a Source object, which could then be asked for an InputStream etc. When the Source object is no longer needed it must be released using the resolver. This is very similar like looking up components from a ComponentLocator. In fact a source object can implement most lifecycle interfaces like Composable, Initializable, Disposable etc. @author Avalon Development Team @version CVS $Revision: 1.7 $ $Date: 2004/02/28 11:47:26 $
