31 // Generate the self-patching vtable method:
32 //
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();
40 //
41 // The dummy method is called with the Klass object as the first
42 // operand, and an object as the second argument.
43 //
44
45 //=====================================================================
46
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.
