       Tree::Simple::Visitor::LoadClassHierarchy - A Visitor for loading class hierarchies into a
       Tree::Simple hierarchy


         use Tree::Simple::Visitor::LoadClassHierarchy;

         # create an visitor
         my $visitor = Tree::Simple::Visitor::LoadClassHierarchy->new();

         # set class as an instance, or

         # as a package name

         # pass our visitor to the tree

         # the $tree now mirrors the inheritance hierarchy of the $class


       This visitor will traverse a class's inheritance hierarchy (through the @ISA arrays) and
       create a Tree::Simple hierarchy which mirrors it.


       new There are no arguments to the constructor the object will be in its default state. You
           can use the "setNodeFilter" method to customize its behavior.

       includeTrunk ($boolean)
           Setting the $boolean value to true (1) will cause the node value of the $tree object
           passed into "visit" to be set with the root value found in the class hierarchy.
           Setting it to false (0), or not setting it, will result in the first value in the
           class hierarchy creating a new node level.

       includeMethods ($boolean)
           Setting the $boolean value to true (1) will cause methods to be added as a children of
           the class node. Setting it to false (0), or not setting it, will result in this not

           NOTE: Methods are sorted ascii-betically before they are added to the tree. This
           allows a more predictable hierarchy.

       setClass ($class)
           The argument $class should be either a class name or an instance, it is then used as
           the root from which to determine the class hierarchy.

       setNodeFilter ($filter_function)
           This method accepts a CODE reference as its $filter_function argument and throws an
           exception if it is not a code reference. This code reference is used to filter the
           tree nodes as they are created, the $filter_function is passed the node value
           extracted from the hash prior to it being inserted into the tree being built. The
           $filter_function is expected to return the value desired for inclusion into the tree.

       visit ($tree)
           This is the method that is used by Tree::Simple's "accept" method. It can also be used
           on its own, it requires the $tree argument to be a Tree::Simple object (or derived
           from a Tree::Simple object), and will throw and exception otherwise.

           The $tree argument which is passed to "visit" must be a leaf node. This is because
           this Visitor will create all the sub-nodes for this tree. If the tree is not a leaf,
           an exception is thrown. We do not require the tree to be a root though, and this
           Visitor will not affect any nodes above the $tree argument.


       Improve the "includeMethods" functionality
           I am not sure the tree this creates is the optimal tree for this situation. It is
           sufficient for now, until I have more of an actual need for this functionality.

       Add "includeFullSymbolTable" functionality
           This would traverse the full symbol tables and produce a detailed tree of everything
           it finds. This takes a lot more work, and as I have no current need for it, it remains
           in the TO DO list.


       None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to
       fix it.


       See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more information.


       These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in
       the Tree::Simple module, you should refer to that module for more information.
