Locality Preserving Hash Function

Question

Is there any Java library that provides an implementation (or several) of a Locality Preserving Hash Function for Strings?

For what Java type? E.g. `Integer.hashCode()` already has this property. How do you define distance between Strings or arbitrary Java objects? — Tomasz Nurkiewicz, Aug 24 '11 at 07:53
@tomasz distance betweens string can be obtained by converting their characters to ascii — Suraj Chandran, Aug 24 '11 at 08:02
At least I know two possible distances - Levenshtein distance and lexicographical distance. — kan, Aug 24 '11 at 08:09
I didn't specify but I am looking for a locality preserving hash function for Strings — Laurent, Aug 24 '11 at 17:19
