/* This macro defines the structure of the CiTargetMethod - classes.
 * It will generate classes with accessors similar to javaClasses.hpp, but with specializations for oops, Handles and jni handles.
 *
 * The public interface of these classes will look like this:

 * class CiStackSlot : AllStatic {
 * public:
 *   static klassOop klass();
 *   static jint  index(oop obj);
 *   static jint  index(Handle obj);
 *   static jint  index(jobject obj);

 *   static void set_index(Handle obj, jint x);
 *   static void set_index(jobject obj, jint x);
