Examples of javax.jdo.Query.executeWithMap()

javax.jdo.Query.executeWithMap()
Execute the query and return the filtered Collection. The query is executed with the parameters set by the Map values. Each Map entry consists of a key which is the name of the parameter in the declareParameters method, and a value which is the value used in the execute method. The keys in the Map and the declared parameters must exactly match or a JDOUserException is thrown. @return the filtered Collection. @see #executeWithArray(Object[] parameters) @param parameters the Map containing all of the parameters.

            query.declareParameters("Integer param");
            query.setFilter("x == param");
        
            Map actualParams = new java.util.HashMap();
            actualParams.put("param", new Integer(2) );
            Object results = query.executeWithMap(actualParams);


            // check query result
            List expected = new ArrayList();
            Object p3 = new PCPoint(2, 2);
            expected.add(p3);
