NAME
Tree::Simple::Visitor::VariableDepthClone - A Visitor for cloning parts of Tree::Simple hierarchySYNOPSIS
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 = $visitor->getClone();
DESCRIPTION
This visitor will cloneMETHODS
- new
- There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" method to customize its behavior.
- includeTrunk ($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
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
