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