Examples of org.apache.excalibur.source.SourceParameters

org.apache.excalibur.source.SourceParameters
This class holds parameters for a Source object. It differs from the usual Parameters object because it can hold more than one value for a parameter, as is the case for HTTP request parameters.
Only particular kinds of Source implementations, such as {@link org.apache.excalibur.source.impl.URLSource} support this kind ofparameters, passed as the {@link SourceResolver#URI_PARAMETERS} entryin the parameters argument of {@link SourceResolver#resolveURI(String,String,Map)}. @author Avalon Development Team @version $Id: SourceParameters.java,v 1.4 2004/02/28 11:47:26 cziegeler Exp $
