Well, there's the cprops library, but I'd need to make a package out of that first....

http://cprops.sourceforge.net/

Seems like this might be generically useful (i.e. not just for radix tries but the other search types).

Not sure if the threading support is needed or not... plus it might mean that it package only works on Linux (and not Win32, which Perl requires be supported).

I'm the CPAN owner of Net::Patricia (perl-Net-Patricia.rpm) and it currently supports IPv4 and IPv6.

Both are done with specialized data structures.

I'm looking for something that handles a more generic binary data blob... so that I could have arbitrary searches.

For instance, in Perl, I could seed the tree with:

$key = join('.', reverse(split(/./, $domain))); $keylen = length($key) * 8;

and then do rDNS tree searches for hostnames.

One could similarly imagine converting phone numbers into BCD and doing E.164 searches in such a tree.

Net::Patricia currently uses a modified version of libpatricia from the MERIT Radius or SNMP code (forget which)... but it only handles IPv6 and IPv4 as I said.

Ideally it would be an external library that I could just link to.

Anyone have a pointer?

Thanks,
