NAME

       Tree::Simple::Visitor::VariableDepthClone - A Visitor for cloning parts of Tree::Simple
       hierarchy

SYNOPSIS

         use Tree::Simple::Visitor::VariableDepthClone;

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

         $visitor->setCloneDepth(3);

         # pass our visitor to the tree
         $tree->accept($visitor);

         my $partial_tree = $visitor->getClone();

DESCRIPTION

       This visitor will clone

METHODS

       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)
           Based upon the value of $boolean, this will tell the visitor to include the trunk of
           the tree in the traversal as well. This basically means it will clone the root node as
           well.

       setCloneDepth ($number)
       setNodeFilter ($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 cloned.

       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.

       getClone
           This method returns the cloned partial tree.

BUGS

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

CODE COVERAGE

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

SEE ALSO

       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.
