NAME

       jtb - syntax tree builder for JavaCC

SYNOPSIS

       jtb [options] inputfile

DESCRIPTION

       This manual page documents briefly the jtb command.

       JTB (Java Tree Builder) is a syntax tree builder and visitors generator to be used in front of JavaCC (Java Compiler Compiler).	It takes a
       JavaCC grammar file as input (usually a ".jtb" file) and automatically generates the following:

	      - a set of syntax tree classes based on the productions in the grammar, utilizing the Visitor design pattern;

	      - four interfaces: IVoidVisitor, IVoidArguVisitor, IRetVisitor, IRetArguVisitor;

	      - four depth-first visitors: DepthFirstVoidVisitor, DepthFirstVoidArguVisitor, DepthFirstRetVisitor, DepthFirstREtArguVisitor, whose
	      default  methods simply visit the children of the current node; a JavaCC grammar ".jj" file (jtb.out.jj by default), with the proper
	      annotations to build the syntax tree during parsing (which then must be compiled with JavaCC).

       New visitors, which subclass any generated one, can then override the default methods and perform various operations on and manipulate  the
       generated syntax tree.

OPTIONS

       -cl    Print a list of the classes generated to standard out.

       -d dir "-d dir" is short for (and overwrites) "-nd dir/syntaxtree -vd dir/visitor".

       -dl    Generate depth level info.

       -e     Suppress JTB semantic error checking.

       -f     Use descriptive node class field names.

       -h     Display this help message and quit.

       -ia    Inline visitors accept methods on base classes.

       -jd    Generate JavaDoc-friendly comments in the nodes and visitor.

       -nd NAME
	      Use NAME as the package for the syntax tree nodes.

       -np NAME
	      Use NAME as the package for the syntax tree nodes.

       -ns NAME
	      Use NAME as the class which all node classes will extend.

       -o NAME
	      Use NAME as the filename for the annotated output grammar.

       -p NAME
	      "-p pkg" is short for (and overwrites) "-np pkg.syntaxtree -vp pkg.visitor".

       -pp    Generate parent pointers in all node classes.

       -printer
	      Generate a syntax tree dumping visitor.

       -si    Read from standard input rather than a file.

       -scheme
	      Generate Scheme records representing the grammar and a Scheme tree building visitor.

       -tk    Generate special tokens into the tree.

       -vd NAME
	      Use NAME as the package for the default visitor classes.

       -vp NAME
	      Use NAME as the package for the default visitor classes.

       -w     Do not overwrite existing files.

NAME

       Tree::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
       module for more information.
