Having done a lot with this in Win32::TieRegistry, I'd advice you to use separate classes for the tied hash and the object. So, for example, have a class My::Module::Hash which is what you tie the hashes to. Then just bless a reference to such a tied hash into the My::Module class.

You don't strictly have to do it this way, but it removes so much confusion that it is well worth it. Win32::TieRegistry uses the same class for each. It works pretty well but most methods have to check whether they are being called from a blessed ref to a tied hash or directly via an object. The worst case is DESTROY which gets called twice per object because of this and the way that "global destruction" works in current versions of Perl makes it complex to tell what is going on in some cases.

Perl even supports "self-tied" things, but those get very confusing and more than once this support has been broken such that simple things become infinite loops. So I say avoid that.

Use:  <p> text here (a paragraph) </p>

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.
