| // Generate the self-patching vtable method: |
| // |
| // This method will be called (as any other Klass virtual method) with |
| // the Klass itself as the first argument. Example: |
| // |
| // oop obj; |
| // int size = obj->klass()->klass_part()->oop_size(this); |
| // |
| // for which the virtual method call is Klass::oop_size(); |
| // |
| // The dummy method is called with the Klass object as the first |
| // operand, and an object as the second argument. |
| // |
| |
| //===================================================================== |
| |
| // All of the dummy methods in the vtable are essentially identical, |
| // differing only by an ordinal constant, and they bear no releationship |
| // to the original method which the caller intended. Also, there needs |
| // to be 'vtbl_list_size' instances of the vtable in order to |
| // differentiate between the 'vtable_list_size' original Klass objects. |
