131 .IX Title "Tree::Simple::Visitor::VariableDepthClone 3"
132 .TH Tree::Simple::Visitor::VariableDepthClone 3 "2005-10-24" "perl v5.8.7" "User Contributed Perl Documentation"
134 Tree::Simple::Visitor::VariableDepthClone \- A Visitor for cloning parts of Tree::Simple hierarchy
136 .IX Header "SYNOPSIS"
138 \& use Tree::Simple::Visitor::VariableDepthClone;
142 \& # create an visitor
143 \& my $visitor = Tree::Simple::Visitor::VariableDepthClone\->new();
147 \& $visitor\->setCloneDepth(3);
151 \& # pass our visitor to the tree
152 \& $tree\->accept($visitor);
156 \& my $partial_tree = $visitor\->getClone();
159 .IX Header "DESCRIPTION"
160 This visitor will clone
165 There are no arguments to the constructor the object will be in its default state. You can use the \f(CW\*(C`setNodeFilter\*(C'\fR method to customize its behavior.
166 .IP "\fBincludeTrunk ($boolean)\fR" 4
167 .IX Item "includeTrunk ($boolean)"
168 Based upon the value of \f(CW$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.
169 .IP "\fBsetCloneDepth ($number)\fR" 4
170 .IX Item "setCloneDepth ($number)"
172 .IP "\fBsetNodeFilter ($filter_function)\fR" 4
173 .IX Item "setNodeFilter ($filter_function)"
175 This method accepts a \s-1CODE\s0 reference as its \f(CW$filter_function\fR argument and throws an exception if it is not a code reference. This code reference is used to filter the tree nodes as they are cloned.
176 .IP "\fBvisit ($tree)\fR" 4
177 .IX Item "visit ($tree)"
178 This is the method that is used by Tree::Simple's \f(CW\*(C`accept\*(C'\fR method. It can also be used on its own, it requires the \f(CW$tree\fR argument to be a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
179 .IP "\fBgetClone\fR" 4
181 This method returns the cloned partial tree.
184 None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
186 .IX Header "CODE COVERAGE"
187 See the \fB\s-1CODE\s0 \s-1COVERAGE\s0\fR section in Tree::Simple::VisitorFactory for more inforamtion.
189 .IX Header "SEE ALSO"
190 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.
