As others said, I'd rather preferre a simple object to a tie.

In your case it (yet) seems sufficient to bless a scalar ref instead of a hash ref. So you can fetch and store your link with $$ dereferencing.

Of course this doesn't scale well when your object needs more data...

Then lvalue mutators maybe a handy alternative... but to validate the stored links you need again a tie on the data, see Re: A tale about accessors, lvalues and ties

#!/usr/bin/perl use strict; use warnings; $\="\n"; { package LinkClass; sub new { my $scalar="link"; my $self=\$scalar; bless $self; return $self; } sub print {print ${$_[0]}} sub url :lvalue { ${$_[0]} } } my $obj=LinkClass->new(); $obj->print(); $$obj="link2"; $obj->print(); $obj->url="link3"; $obj->print(); __END__ link link2 link3

a completely other approach maybe using a wrapper write(), which calls tied($var)->print_method; like Arunbear suggested.

write() could be automatically imported with your Linkpackage...

Cheers Rolf

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.
