Tree::Simple::Visitor:UseriContribTree::Simple::Visitor::VariableDepthClone(3)NAMETree::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
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
