.SH "NAME"
Tree::Simple::Visitor::VariableDepthClone \- A Visitor for cloning parts of Tree::Simple hierarchy
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  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);
\&

.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This visitor will clone
.SH "METHODS"
.IX Header "METHODS"
.IP "\fBnew\fR" 4
.IX Item "new"
There are no arguments to the constructor the object will be in its default state. You can use the \f(CW\*(C`setNodeFilter\*(C'\fR method to customize its behavior.
.IP "\fBincludeTrunk ($boolean)\fR" 4
.IX Item "includeTrunk ($boolean)"
Based upon the value of \f(CW$boolean\fR, this will tell the visitor to include the trunk of the tree in the traversal as well. This basically means it will clone the root node as well.
.IP "\fBsetCloneDepth ($number)\fR" 4
.IX Item "setCloneDepth ($number)"
.PD 0
.IP "\fBsetNodeFilter ($filter_function)\fR" 4
.IX Item "setNodeFilter ($filter_function)"
.PD
This method accepts a \s-1CODE\s0 reference as its \f(CW$filter_function\fR 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.
.IP "\fBvisit ($tree)\fR" 4
.IX Item "visit ($tree)"
This is the method that is used by Tree::Simple's \f(CW\*(C`accept\*(C'\fR method. It can also be used on its own, it requires the \f(CW$tree\fR argument to be a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
.IP "\fBgetClone\fR" 4
.IX Item "getClone"
This method returns the cloned partial tree.
.SH "BUGS"
.IX Header "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.
.SH "CODE COVERAGE"
.IX Header "CODE COVERAGE"
See the \fB\s-1CODE\s0 \s-1COVERAGE\s0\fR section in Tree::Simple::VisitorFactory for more inforamtion.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
These Visitor classes are all subclasses of \fBTree::Simple::Visitor\fR, which can be found in the \fBTree::Simple\fR module, you should refer to that module for more information.
