Tree::Simple::Visitor::VariableDepthClone3pm

Usage

  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();

Overview

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 the Tree::Simple "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.
