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