This example creates an unbounded simple data array of the type returned by the getDataType method, which returns a string of the form dt_type. Most of the case statements have been removed for the sake of brevity:

if (d_returnType.isArray())
   {
      returnValue.l = env->CallObjectMethodA(obj,
         mid, values.get());
      pbarray v;
 
      switch(d_returnType.getDataType())
      {
      case dt_boolean:
         v = session->NewUnboundedSimpleArray
            (pbvalue_boolean);
         break;
 
      case dt_short:
         v = session->NewUnboundedSimpleArray
            (pbvalue_int);
         break;
// CASE statements omitted
...
      default:
         v = session->NewUnboundedSimpleArray
            (pbvalue_any);
         break;
      }
 
      ci->returnValue->SetArray(v);
