Subject: Hash-tables containing references to hash-tables
Date: Mon, 23 Nov 2009 03:12:22 -0800 (PST) [thread overview]
Message-ID: <7a116be4-52cb-482d-b555-09bc4950d5f7@31g2000vbf.googlegroups.com> (raw)
Is it possible for a hash-table to contain a *reference* to another
hash-table, similar to how we can build arbitrary graphs using conses/
lists and setf?
If so how? If not, is there reason for being so or is it just an emacs
todo?
If we have
(puthash parent-key (make-hash-table : size CHILD-SIZE) parent-hash)
then I want
(gethash parent-key parent-hash)
to return a *reference* to hash-table contained in parent-hash.
I already have a working code for this but I am uncertain how this
will perform when CHILD-SIZE is really large.
