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

10 use Tree::Simple::Visitor::VariableDepthClone;
11
12 # create an visitor
13 my $visitor = Tree::Simple::Visitor::VariableDepthClone->new();
14
15 $visitor->setCloneDepth(3);
16
17 # pass our visitor to the tree
18 $tree->accept($visitor);
19
20 my $partial_tree = $visitor->getClone();
21
23 This visitor will clone
24
26 new There are no arguments to the constructor the object will be in its
27 default state. You can use the "setNodeFilter" method to customize
28 its behavior.
29
30 includeTrunk ($boolean)
31 Based upon the value of $boolean, this will tell the visitor to
32 include the trunk of the tree in the traversal as well. This basi‐
33 cally means it will clone the root node as well.
34
35 setCloneDepth ($number)
36 setNodeFilter ($filter_function)
37 This method accepts a CODE reference as its $filter_function argu‐
38 ment and throws an exception if it is not a code reference. This
39 code reference is used to filter the tree nodes as they are cloned.
40
41 visit ($tree)
42 This is the method that is used by Tree::Simple's "accept" method.
43 It can also be used on its own, it requires the $tree argument to
44 be a Tree::Simple object (or derived from a Tree::Simple object),
45 and will throw and exception otherwise.
46
47 getClone
48 This method returns the cloned partial tree.

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

55 See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more
56 inforamtion.

59 These Visitor classes are all subclasses of Tree::Simple::Visitor,
60 which can be found in the Tree::Simple module, you should refer to that
61 module for more information.
