public class Metaclass

extends OJClass

The class Metaclass is a metametaclass for metaclasses. You can write a metaclass easily using this class.

For example,

 public class MyClass instantiates Metaclass extends OJClass
 {
     convenient void f() {
         .. String.class ..;
         .. oldjavaclass.String.class ..;
     }
     void g() {
         .. String.class ..;
     }
 }
 

Here, you don't have to write constructors if your program don't concern. And class literal doesn't represent java.lang.Class object but openjava.mop.OJClass.

The above code is to be translated into:

 public class MyClass instantiates Metaclass extends OJClass
 {
     void f() {
         .. openjava.mop.OJClass.forClass( String.class ) ..;
         .. java.lang.String.class ..;
     }
     void g() {
         .. java.lang.String.class ..;
     }
     void translateDefinition() {
         OJClass c1 = openjava.mop.OJClass.forClass( String.class );
         OJClass c2 = String.class;
     }
     public MyClass(Environment e, OJClass d, ClassDeclaration p) {
         super(e,d,p);
     }
     public MyClass(Class c, MetaInfo m) {
         super(c,m);
     }
 }
