When you want to extend an existing class, you have two options: inheritance and aggregation. If you go the inheritance route your new method would look something like this:

use base qw(Net::FTP); #5.8 #or for 5.10 and up #use parent qw(Net::FTP); sub new { my ($pkg, $server, $user, $timeout, @args) = @_; # some special class specific stuff # ... is params for super class structure my $self = $pkg->SUPER::new(...); $self->server($server); $self->user($user); $self->timeout($timeout); $self->initialize(); # some special class specific stuff # if SUPER::new is well behaved, $self will be a member # of the $pkg class even though it was built by the # the super class. return $self; }

If you go the aggregation route you might do something like this:

sub new { my ($pkg, $server, $user, $timeout, @args) = @_; # some special class specific stuff # ... is params for super class structure my $ftp = Net::FTP->new(...); $ftp->server($server); $ftp->user($user); $ftp->timeout($timeout); $ftp->initialize(); my $self = { ftpHandle => $ftp }; return bless($self, $pkg); }

If you want your own class to be implemented using a hash, you would go with the aggregation approach since Net::FTP doesn't return a hash. If you want to return the same kind of implementation as Net::FTP, then you would follow the inheritance pattern. You might find the sections on inheritance and aggregation in perltoot worth a read.

Best, beth

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
