org.apache.cocoon.environment.Source
Description of a source. This interface provides a simple interface for accessing a source of data. The source of data is assumed to not change during the lifetime of the Source object. If you have a data source that can change its content and you want it to reflect in Cocoon, use a {@link ModifiableSource} object instead. @author Carsten Ziegeler @author Ovidiu Predescu @version CVS $Revision: 1.6.2.7 $ $Date: 2001/10/11 08:56:10 $
