Re: arrays of object in OO perl

Unfortunately, the biggest problem with using references seems to be getting the syntax right. Try thi:

sub getIndividual{
    my $this = shift;
    my $index = shift;
    return $this->{individual}->[$index]->getDNA();
}

The problem with your version was you were trying to call a method on an array slice.

I tried with the suggested code `return $this->{individual}->[$index]->getDNA();` but the output is always the same: `Can't call method "getDNA" on an indefined value at Population.pm ...` I want to point out that I don't push into Population empty arrays.	[reply] [d/l] [select]
