It seems to me that dealing with references and and parallel decorations of references seems pretty complex for folk not expert in these things. A simpler approach may be to abstract away the graph representation and algorithms from the objects themselves and create a graph object proper with objects associated with the nodes.

This can probably be done most easily by using Graph::Directed to handle graph stuff and adding node number to the object's data to be set upon initialization. The module has all the (basic) graph methods you could want, with no worries about dereferencing, just simple method calls.

Title:
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.
