You could always just shove it into a database with an index. {grin}

I'm not a CS expert, but I think a B-tree might be the right structure (see Pure Perl B-Tree managers are available, such as Tree and Btrees. I think even a Berkeley DB can be stored "in core" with the BerkeleyDB module, and there's a B-Tree version of that.

update: yes, with DB_File, you can set up an in-memory DB (use undef for the filename), and with the right comparison callback, you get basic operations like
## add a new $nextevent at $time: push @{$db{$time}}, $nextevent; ## get the lowest event list keys %db; # reset pointer my ($time, $events) = each %db; # lowest events

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.
