I am currently looking into using structures in a program I am working on. For readability, I was wanting to use structures. Now I found the Class::Struct module and was using that, but then I found that
Perl 5 Version 12.2 has Elaborate Records which are very similar to structures from what I can see.
Now to build my skills with Perl, I am investigating how to use references, and references with arrays in these elaborate records.
The Problem:
I would like to learn how to retrieve the value for a reference to a scalar from an elaborate record and how to
work with references to elaborate records.
my $stg_username = "PerlMonk";
my $stg_password = "VeryGoodPassword";
my @ary_email_address = [ "Monk1", "Monk2", "Monk3" ];
$EllabRecord = { m_username => \$stg_username
, m_password => \$stg_password
, m_emailAddress => \[@ary_email_address] };
print $stg_username;
print $EllabRecord->{m_password}; #prints out "SCALAR (0xAABBCC)"
&PrintArray( \$EllabRecord );
sub PrintArray {
$reference = $_[0];
print $$reference->[m_emailAddress]->[0], "\n"; #gives a "Not an A
+RRAY reference at...Line XX"
}
If you can either provide me with clear code examples or a good guide to how this is done, either would be greatly appreciated. Thanking you in advance.
