There are two potentially interesting things - * about this implementation: - * - * 1) The table is power-of-two sized. Prime sized tables are more - * traditional, but do not have a significant advantage over power-of-two - * sized table, especially when double hashing is not used for collision - * resolution. - * - * 2) The hash computation uses a table of random integers [Hanson97, - * pp. 39-41]. - * - * FUTURE ENHANCEMENTS - * - * With a table size of 512, the current implementation is sufficient for a - * few hundred keys. Since this is well above the expected size of the - * tables for which this implementation was designed, the implementation of - * dynamic hash tables was postponed until the need arises. A common (and - * naive) approach to dynamic hash table implementation simply creates a - * new hash table when necessary, rehashes all the data into the new table, - * and destroys the old table. The approach in [Larson88] is superior in - * two ways: 1) only a portion of the table is expanded when needed, - * distributing the expansion cost over several insertions, and 2) portions - * of the table can be locked, enabling a scalable thread-safe - * implementation. - * - * REFERENCES - * - * [Hanson97] David R.
