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.
