33 // This method will be called (as any other Klass virtual method) with | |
34 // the Klass itself as the first argument. Example: | |
35 // | |
36 // oop obj; | |
37 // int size = obj->klass()->klass_part()->oop_size(this); | |
38 // | |
39 // for which the virtual method call is Klass::oop_size(); | |

47 // All of the dummy methods in the vtable are essentially identical, | |
48 // differing only by an ordinal constant, and they bear no releationship | |
49 // to the original method which the caller intended. Also, there needs | |
50 // to be 'vtbl_list_size' instances of the vtable in order to | |
51 // differentiate between the 'vtable_list_size' original Klass objects. | |
