( #3333=superdoc: print w/replies, xml ) Need Help??

I have no idea what everyone is talking about. Inside-out objects where invented precisely to make it possible to inherit without knowing any superclass implementation details. The sole trick to that is to let your superclass set up the blessed reference for you, then rebless it into your own package. After all, you don’t even care what the reference actually contains, all you need is an address.

sub new { my ( $class, $samba ) = @_; my $self = $class->SUPER::new( $samba ); $config_of{ ident $self } = $samba; return bless $self, $class; }

How else can File::Samba work, anyway, if you don’t let it initialise its own data structures by calling its constructor?

Update: you don’t actually need to rebless the reference (unless your superclass is misbehaved).

sub new { my ( $class, $samba ) = @_; my $self = $class->SUPER::new( $samba ); $config_of{ ident $self } = $samba; return $class; }

Makeshifts last the longest.

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 or How to display code and escape characters are good places to start.
