Tree::Simple::Visitor::BreadthFirstTraversal(3pm)	User Contributed Perl Documentation	 Tree::Simple::Visitor::BreadthFirstTraversal(3pm)

NAME
Tree::Simple::Visitor::BreadthFirstTraversal - A Visitor for breadth-first traversal a Tree::Simple hierarchy SYNOPSIS
use Tree::Simple::Visitor::BreadthFirstTraversal; # create an visitor my $visitor = Tree::Simple::Visitor::BreadthFirstTraversal->new(); # pass our visitor to the tree $tree->accept($visitor); # print our results print join ", " => $visitor->getResults(); # this will print this: # 1, 2, 3, 1.1, 1.2, 2.1, 3.1, 1.1.1 # assuming your tree is like this: # 1 # 1.1 # 1.1.1 # 1.2 # 2 # 2.1 # 3 # 3.1 DESCRIPTION
This implements a breadth-first traversal of a Tree::Simple hierarchy. This can be an alternative to the built in depth-first traversal of the Tree::Simple "traverse" method. METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" method to customize its behavior. includeTrunk ($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. 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 inforamtion. 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. AUTHOR
