NAME

       Log::NullLogLite - The "Log::NullLogLite" class implements the Null Object pattern for the "Log::LogLite" class.

SYNOPSIS

	 use Log::NullLogLite;

	 # create new Log::NullLogLite object
	 my $log = new Log::NullLogLite();

	 ...

	 # we had an error (this entry will not be written to the log
	 # file because we use Log::NullLogLite object).
	 $log->write("Could not open the file ".$file_name.": $!", 4);

DESCRIPTION

       The "Log::NullLogLite" class is derived from the "Log::LogLite" class and implement the Null Object Pattern to let us to use the
       "Log::LogLite" class with null "Log::LogLite" objects.  We might want to do that if we use a "Log::LogLite" object in our code, and we do
       not want always to actually define a "Log::LogLite" object (i.e. not always we want to write to a log file). In such a case we will create
       a "Log::NullLogLite" object instead of the "Log::LogLite" object, and will use that object instead.  The object has all the methods that
       the "Log::LogLite" object has, but those methods do nothing. Thus our code will continue to run without any change, yet we will not have to
       define a log file path for the "Log::LogLite" object, and no log will be created.

CONSTRUCTOR

       new ( FILEPATH [,LEVEL [,DEFAULT_MESSAGE ]] )
	   The constructor. The parameters will not have any affect.  Returns the new Log::NullLogLite object.
