collision resolution scheme


Definition: A way of handling collisions, that is, when two or more items should be kept in the same location, especially in a hash table. The general ways are keeping subsequent items within the table and computing possible locations (open addressing), keeping lists for items that collide (chaining), or keeping one special overflow area.

Specialization (... is a kind of me.)
direct chaining, open addressing, separate chaining.

Aggregate parent (I am a part of or used in ...)
hash table.

Note: The special overflow area can be any searchable data structure, even another (smaller) hash table.
