NAME

       Net::XMPP::Debug - XMPP Debug Module

SYNOPSIS

       Net::XMPP::Debug is a module that provides a developer easy access to logging debug
       information.

DESCRIPTION

       Debug is a helper module for the Net::XMPP modules.  It provides the Net::XMPP modules
       with an object to control where, how, and what is logged.

   Basic Functions
           $Debug = Net::XMPP::Debug->new();

           $Debug->Init(
                  level  => 2,
                  file   => "stdout",
                  header =>"MyScript");

           $Debug->Log0("Connection established");

METHODS

   Basic Functions
       new
               new(hash)

           creates the Debug object.  The hash argument is passed to the Init function.  See that
           function description below for the valid settings.

       Init
               Init(
                    level      => integer,
                    file       => string,
                    header     => string,
                    setdefault => 0|1,
                    usedefault => 0|1,
                    time       => 0|1)

           initializes the debug object.

           The level determines the maximum level of debug messages to log:

             0 - Base level Output (default)
             1 - High level API calls
             2 - Low level API calls
             ...
             N - Whatever you want....

           The file determines where the debug log goes.  You can either specify a path to a
           file, or "stdout" (the default).  "stdout" tells Debug to send all of the debug info
           sent to this object to go to stdout.

           header is a string that will preappended to the beginning of all log entries.  This
           makes it easier to see what generated the log entry (default is "Debug").

           setdefault saves the current filehandle and makes it available for other Debug objects
           to use.  To use the default set usedefault to 1.

           The time parameter specifies whether or not to add a timestamp to the beginning of
           each logged line.

       LogN
             LogN(array)

           Logs the elements of the array at the corresponding debug level N.  If you pass in a
           reference to an array or hash then they are printed in a readable way.  (ie... Log0,
           Log2, Log100, etc...)

EXAMPLE

         $Debug = Net::XMPP:Debug->new(level=>2,
                                      header=>"Example");

         $Debug->Log0("test");

         $Debug->Log2("level 2 test");

         $hash{a} = "atest";
         $hash{b} = "btest";

         $Debug->Log1("hashtest", \%hash);

       You would get the following log:

           Example: test
           Example: level 2 test
           Example: hashtest { a=>"atest" b=>"btest" }

       If you had set the level to 1 instead of 2 you would get:

           Example: test
           Example: hashtest { a=>"atest" b=>"btest" }
