Detailed Description

A hash table Usually the hashtable is generated by the create_hash_table script, from a .table file.

The implementation uses an array of entries, "size" is the total size of that array. The entries between 0 and hashSize-1 are the entry points for each hash value, and the entries between hashSize and size-1 are the overflow entries for the hash values that need one. The "next" pointer of the entry links entry points to overflow entries, and links overflow entries between them.
