Hi,

I could really do with a hand on some OO perl that I'm battling with please perlmonks.

Here is what I'm trying to do: I have 2 packages

LogSimple
DEC::Project
[download]

The LogSimple logging object is created like so, the important piece to focus on here in this object is the function reference stored in 'exit'

my $log = LogSimple->new(
        logdir => $logdir,
        logfile => $logfile,
        loglevel => $loglevel,
        verbosity => $verbosity,
        exit      => \&DEC::Project::exit_routine
);
[download]

Next I initialise the following object, there can be multiples of these with different serial numbers.

my $server = DEC::Project->new(
        serial => '17353',
        log    => $log,
);
[download]

The LogSimple object handles any exit from the project like this:

$log->err("Something went wrong",1);
[download]

Where the script would exit 1. I use the LogSimple package in other projects and have recently added the optional ability to make a callback so that 'stuff' can take place before the exit..

Now, when something goes wrong talking to $server object I would like to call the subroutine

\&DEC::Project::exit_routine

I can get exit_routine to execute except I want to be able to issue commands to all of the $server objects from \&DEC::Project::exit_routine just before the exit.

I am trying to store references to all of the $server objects as they are created in ->new inside a global hash like this:

$server_objects{$options{'serial'}} = \$self;
[download]

My thinking is that I should be able to loop through the hash executing whatever methods I need against all of the objects like this:

sub exit_routine {
for my $serial ( keys %server_objects ) {
        my $server = $server_objects{$serial};
        my @ret = $server->logout();
}

}

sub logout {
    my $self = shift;
print "logging out";
}

};
[download]

However I keep running into the following: Can't call method "logout" on unblessed reference

This is my first real venture into OO programming so this is a real challenge for me. Anyone able to offer advice ?

Many thanks, Darren
