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");

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);
