Not really but:
Why "Log::Log4perl->get_logger" and not "Log::Log4perl->new"? We don't
want to create a new
object every time. Usually in OO-Programming, you create an object
once and use the
reference to it to call its methods. However, this requires that you
pass around the object
to all functions and the last thing we want is pollute each and
every function/method we're
using with a handle to the "Logger":
sub function { # Brrrr!!
my($logger, $some, $other, $parameters) = @_;
}
Instead, if a function/method wants a reference to the logger, it
just calls the Logger's
static "get_logger($category)" method to obtain a reference to the
one and only possible
logger object of a certain category. That's called a singleton if
you're a Gamma fan.
and so:
#$logger->get_logger('LOG2');
$logger = Log::Log4perl->get_logger('LOG2');
seems to work.
