NAME

       Tree::Simple::Visitor::CreateDirectoryTree - A Visitor for create a set of directories and
       files from a Tree::Simple object

SYNOPSIS

         use Tree::Simple::Visitor::CreateDirectoryTree;

         # create a Tree::Simple object which
         # represents a directory hierarchy
         my $tree = Tree::Simple->new("www/")
                           ->addChildren(
                               Tree::Simple->new("conf/")
                                   ->addChildren(
                                       Tree::Simple->new("startup.pl"),
                                       Tree::Simple->new("httpd.conf")
                                   ),
                               Tree::Simple->new("cgi-bin/"),
                               Tree::Simple->new("ht_docs/"),
                               Tree::Simple->new("logs/")
                                   ->addChildren(
                                       Tree::Simple->new("error.log"),
                                       Tree::Simple->new("access.log")
                                   ),
                           );

         # create an instance of our visitor
         my $visitor = Tree::Simple::Visitor::CreateDirectoryTree->new();

         # pass the visitor to a Tree::Simple object
         $tree->accept($visitor);

         # the www/ directory now mirrors the structure of the tree

DESCRIPTION

       This visitor can be used to create a set of directories and files from a Tree::Simple
       object hierarchy.

METHODS

       new There are no arguments to the constructor the object will be in its default state. You
           can use the "setNodeFilter", "setFileHandler" and "setDirectoryHandler" methods to
           customize its behavior.

       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 used to create the directory tree, it can be basically used as
           a node pre-processor. An example usage of this might be to enforce the 8.3 naming
           rules of DOS, or the 32 character limit of older macintoshes.

       setFileHandler ($file_handler)
           This method accepts a CODE reference as its $file_handler argument and throws an
           exception if it is not a CODE reference. This method can be used to create custom file
           creation behavior.  The default behavior is to just create the file and nothing else,
           but by using this method it is possible to implement some other custom behavior, such
           as creating a file based on a template.  The function is passed the full path of the
           file to be created (as built by File::Spec).

       setDirectoryHandler ($dir_handler)
           This method accepts a CODE reference as its $dir_handler argument and throws an
           exception if it is not a CODE reference. This method can be used to create custom
           directory creation behavior.  The default behavior is to just create the directory and
           nothing else, but by using this method it is possible to implement some other custom
           behavior, such as creating a directory on a remote server. The function is passed the
           full path of the directory to be created (as built by File::Spec).

       visit ($tree)
           This is the method that is used by the Tree::Simple "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.

           The tree is processed as follows:

           Any node which is not a leaf is considered a directory.
               Obviously since files themselves are leaf nodes, this makes sense that non-leaves
               will be directories.

           Any node (including leaf nodes) which ends in either the character "/" or "\" is
           considered a directory.
               I think it is a pretty standard convention to have directory names ending in a
               separator. The separator itself is stripped off before the directory name is
               passed to File::Spec where the platform specific directory path is created. This
               means that it does not matter which one you use, it will be completely cross
               platform (at least as cross-platform as File::Spec is).

           All other nodes are considered to be files.
