113       *   <li>call visitNewStuff: the redirection test is skipped and 'do stuff' is executed directly.

134       * more, and visitNewStuff is overridden (and visitOldStuff is not). Any other case is a user
135       * programming error.
136       *
137       * <p>If 'api' is equal to API_NEW, the class hierarchy is equivalent to

176       * }

180       *
181       * <ul>
182       *   <li>call visitOldStuff: in the call to super.visitOldStuff, the source is set to
183       *       SOURCE_DEPRECATED and visitNewStuff is called. Here 'do stuff' is run because the source
184       *       was previously set to SOURCE_DEPRECATED, and execution eventually returns to
185       *       UserStuffVisitor.visitOldStuff, where 'do user stuff' is run.
186       *   <li>call visitNewStuff: the call is redirected to UserStuffVisitor.visitOldStuff because the
187       *       source is 0. Execution continues as in the previous case, resulting in 'do stuff' and 'do
188       *       user stuff' being executed, in this order.
189       * </ul>
190       *
191       * <h1>ASM subclasses</h1>
192       *
193       * <p>In ASM packages, subclasses of StuffVisitor can typically be sub classed again by the user,
194       * and can be used with API_OLD or API_NEW. Because of this, if such a subclass must override
195       * visitNewStuff, it must do so in the following way (and must not override visitOldStuff):
196       *
197       * <pre>
198       * public class AsmStuffVisitor extends StuffVisitor {
199       *   &#64;Override public void visitNewStuff(int argAndSource, ...) {
200       *     if (api &#60; API_NEW &#38;&#38; (argAndSource &#38; SOURCE_DEPRECATED) == 0) {
201       *       super.visitNewStuff(argAndSource, ...);
202       *       return;
203       *     }

206       *     [ do other stuff ]
207       *   }
208       * }
209       * </pre>
210       *
211       * <p>If a user class extends this with 'api' equal to API_NEW, the class hierarchy is equivalent
212       * to

235       * class extends AsmStuffVisitor with 'api' equal to API_OLD, the class hierarchy is equivalent to

273       * <h1>Notes</h1>
274       *
275       * <ul>
276       *   <li>the SOURCE_DEPRECATED flag is set only if 'api' is API_OLD, just before calling

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