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
