new()

Call new() to create a new Log::Handler::Output::Forward object.

The following options are possible:

forward_to

This option excepts a code reference.

Please note that the message is forwarded as a hash reference. If you change it then this would have an effect to all outputs.

arguments

With this option you can define arguments that will be passed to the sub routine.

In the following example the arguments would be passed as a array to Class::method().

    my $forwarder = Log::Handler::Output::Forward->new(
        forward_to => \&Class::method,
        arguments  => [ $self, "foo" ],
    );
    

This would call intern:

    Class::method(@arguments, $message);
    

If this option is not set then the message will be passed as first argument.

log()

Call log() if you want to forward messages to the subroutines.

Example:

    $forwarder->log("this message will be forwarded to all sub routines");

validate()

Validate a configuration.

reload()

Reload with a new configuration.

errstr()

This function returns the last error message.
