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.


      String parameterDeclaration = makeParameterDeclarationString(params);
      query.declareParameters(parameterDeclaration);
      query.setOrdering("partitionName ascending");


      List<MPartition> mparts = (List<MPartition>) query.executeWithMap(params);
      // pm.retrieveAll(mparts); // retrieveAll is pessimistic. some fields may not be needed
      List<Partition> results = convertToParts(dbName, tblName, mparts);
      // pm.makeTransientAll(mparts); // makeTransient will prohibit future access of unfetched fields
      query.closeAll();
