Examples of org.apache.turbine.util.parser.ParameterParser

org.apache.turbine.util.parser.ParameterParser
ParameterParser is an interface to a utility to handle parsing and retrieving the data passed via the GET/POST/PATH_INFO arguments.
NOTE: The name= portion of a name=value pair may be converted to lowercase or uppercase when the object is initialized and when new data is added. This behaviour is determined by the url.case.folding property in TurbineResources.properties. Adding a name/value pair may overwrite existing name=value pairs if the names match:
```
 ParameterParser pp = data.getParameters(); pp.add("ERROR",1); pp.add("eRrOr",2); int result = pp.getInt("ERROR"); 
```
In the above example, result is 2. @author Ilkka Priha @author Jon S. Stevens @author Sean Legassick @author Henning P. Schmiedehausen @version $Id: ParameterParser.java 279820 2005-09-09 17:05:54Z henning $
