Detailed Description

Misc. hashing functions, mostly from Bob Jenkins.

Original source file Hasher.H

InNamespace Foam

The Jenkins hashing function(s) is similar in speed to Paul Hsieh's SuperFast hash, but is public domain, supports incremental hashing and has been reported to have better characteristics. It is also what postgresql seems to be using.
