Hi,
Want to know, is there any way to restrict a Solaris user to Single Login. Means a particular user can login once and if he or someone else tries to login with his ID then a message displayed "user already logged in" and denies his attempt.

Tree::Simple::Visitor::CreateDirectoryTree(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::CreateDirectoryTree(3pm)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 heirarchy
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 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.
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.
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.
