static abstract kludge example
Posted by Paul Heimiller on December 19, 2001 at 10:14 AM
I've gotten some questions on this, so here is some code that will hopefully make this clearer. MainController method: public static String getPrimaryTable() { throw new IllegalStateException(" MainCtrll.getPrimaryTable method should be overidden by subclass"); } SubClassedController: public static String getPrimaryTable() { return( "VEHICLE_LINE" ); } Another class, has name of controller: String strMainCtrllr = "SubClassedController"; try { Class mccClass = Class.forName(strMainCtrllr); Method methodMy = mccClass.getMethod("getPrimaryTable", new Class[0]); strPrimaryTable = (String) methodMy.invoke(null, new Object[0]); } } catch (Exception e) { System.out.println(" couldn't get strPrimaryTable for controller " + strMainCtrllr); // e.printStackTrace(System.out); // System.exit(1); }
