140       * more, and visitNewStuff is overridden (and visitOldStuff is not). Any other case is a user
141       * programming error.
142       *
143       * <p>If 'api' is equal to API_NEW, the class hierarchy is equivalent to

186       *
187       * <ul>
188       *   <li>call visitOldSuff: in the call to super.visitOldStuff, the source is set to
189       *       SOURCE_DEPRECATED and visitNewStuff is called. Here 'do stuff' is run because the source
190       *       was previously set to SOURCE_DEPRECATED, and execution eventually returns to
191       *       UserStuffVisitor.visitOldStuff, where 'do user stuff' is run.
192       *   <li>call visitNewStuff: the call is redirected to UserStuffVisitor.visitOldStuff because the
193       *       source is 0. Execution continues as in the previous case, resulting in 'do stuff' and 'do
194       *       user stuff' being executed, in this order.
195       * </ul>
196       *
197       * <h1>ASM subclasses</h1>
198       *
199       * <p>In ASM packages, subclasses of StuffVisitor can typically be sub classed again by the user,
200       * and can be used with API_OLD or API_NEW. Because of this, if such a subclass must override
201       * visitNewStuff, it must do so in the following way (and must not override visitOldStuff):
202       *
203       * <pre>

207       *       super.visitNewStuff(argAndSource, ...);
208       *       return;
209       *     }

215       * </pre>
216       *

280       *
281       * <ul>
282       *   <li>the SOURCE_DEPRECATED flag is set only if 'api' is API_OLD, just before calling

284       *       classes can never see this flag. Only ASM subclasses must take care of extracting the
285       *       actual argument value by clearing the source flags.
286       *   <li>because the SOURCE_DEPRECATED flag is immediately cleared in the caller, the caller can
287       *       call visitOldStuff or visitNewStuff (in 'do stuff' and 'do user stuff') on a delegate
288       *       visitor without any risks (breaking the redirection logic, "leaking" the flag, etc).
289       *   <li>all the scenarios discussed above are unit tested in MethodVisitorTest.
