whoops, got guile's email address screwed up. Jay Glascoe jglascoe@jay.giss.nasa.gov ---------- Forwarded message ---------- Date: Fri, 23 Oct 1998 22:49:42 -0400 (EDT) From: Jay Glascoe <jglascoe@jay.giss.nasa.gov> To: Maciej Stachowiak <mstachow@mit.edu> Cc: guile@gnu.com Subject: Re: Scheme style auto-resizing hashtable and another thing, I'm going to completely re-haul make-hashtab to accept one optional argument: either an alist or a vector of associations. I figure my hash tables do an excellent job of choosing (and modifying) max-bucket-size, and they resize so quickly that an initial number-buckets of 4 is more than adequate. As for the auto-shrink argument, well the user will just have to call hashtab-(en|dis)able themselves. Now, why the optional alist/vector of associations argument? I figure that someone using an alist that grows larger than they expected (say >100) can easily trade it in for a hash table. And any good avl-tree will probably have avl->alist and avl->vector procedures. Jay
