NAME

       Tree::Simple::Visitor::PostOrderTraversal - A Visitor for post-order traversal a
       Tree::Simple hierarchy

SYNOPSIS

         use Tree::Simple::Visitor::PostOrderTraversal;

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

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

         # print our results
         print join ", " => $visitor->getResults();

         # this will print this:
         #   1.1.1 1.1 1.2 1 2.1 2 3.1 3
         # assuming your tree is like this:
         #   1
         #     1.1
         #       1.1.1
         #     1.2
         #   2
         #     2.1
         #   3
         #     3.1

DESCRIPTION

       Post-order traversal is a variation of the depth-first traversal in which the sub-tree's
       are processed before the parent. It is another alternative to Tree::Simple's "traverse"
       method which implements a depth-first, pre-order traversal.

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.

       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 collected. This can be used to customize output, or to gather
           specific information from a more complex tree node. The filter function should accept
           a single argument, which is the current Tree::Simple object.

       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.

       getResults
           This method returns the accumulated results of the application of the node filter to
           the tree.
