9 * Base class for visitors on a bytecode entity. The public {@link #visit}
10 * method will traverse the object graph of the given entity, calling the
11 * <code>enter*</code> and <code>exit*</code> methods as it visits each
12 * object. The traversal is done depth-first. Subclasses should override
13 * only the methods for visiting the entities they are interested in.
14 * Whenever there is a general method (i.e. <code>enter/exitEntry</code>) as
15 * well as a more specific one (i.e. <code>enter/exitStringEntry</code>), the
16 * more general method will be called first, followed by a call on the correct
17 * specific method. Most subclasses will override either the general or
18 * specific cases, but not both.
