You could create accessor functions in the parent that access the children arrays, like:
# Parent sub get_child_id { my $self=shift; my $child=shift; # Find the index of the child. Left as exercise for the reader (read +: I'm too lazy :) ). return $child_index; }
Then your child can get its ID using code such as:
# Child sub whereami { my $self=shift; my $parent=$self->{'parent'}; my $id=$parent->get_child_id($self); }
Note that you have a small error in your child code, BTW: you store a reference to the reference to the parent instead of the parent ref itself. Change the line:
my $self = { parent => \$parent; };
by
my $self= { parent => $parent }; #$parent is a ref, you were storing a + ref to $parent

CU
Robartes-

Update: Changed child sub name to original poster's name: sub whereami.

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