Re: List Wrapper for Object Methods.

You can use AUTOLOAD to do that

our $AUTOLOAD;

sub AUTOLOAD 
{
    my $self = shift;
    my $method = $AUTOLOAD;
    $method =~ s/.*://; # strip out Package::

    foreach my $anything (@{$self}) {
        die "method $method not supported" 
          unless $anything->can($method);
        $anything->$method(@_);
    }
}
[download]

Though this does smell like it would benefit from the composite design pattern.

Thanks a lot Arunbear this works nicely. There's just one thing left for me: I see that my AUTOLOAD method now also "catches" calls for DESTROY and I don't know exactly what's happening then. Isn't the AUTOLOAD method a litte too generic? pelagic	[reply]

To get around that you can add the line `return if $AUTOLOAD =~ /::DESTROY$/;` [download] at the beginning of the AUTOLOAD sub, or define a do-nothing DESTROY method (assuming you really don't have any cleanup to do). Perl calls the DESTROY method when it does garbage collection, even if you haven't defined a DESTROY method.	[reply] [d/l]
