i am writing a java query that needs a parameter (ex : stereotypeName).

public class isStereotyped implements IJavaModelQuery<Element, Boolean> {

       public Boolean evaluate(Element context, ParameterValueList
parameterValues) throws ModelQueryExecutionException {
               String stereotypeName ="";
               if(parameterValues.getParameterValueByName("stereotypeName") ==
null ){
                       //TODO what must i do ?
               }else {
                       stereotypeName  =
(String)parameterValues.getParameterValueByName("stereotypeName").getValue
();
               }
               ....

how will the query user know that the query needs a parameter ?

i think queries need to specify if they have parameters and if the parameters are mandatory or optionnal.

must i throw an IllegalArgumentException, ModelQueryException or ModelQueryExecutionException ?
