chaining

(data structure)

Definition: A class of collision resolution schemes in which linked lists handle collisions in a hash table. The two main subclasses are separate chaining, where lists are outside the table, and coalesced chaining, where the lists are within the table.

Generalization (I am a kind of ...)
collision resolution scheme.

Specialization (... is a kind of me.)
coalesced chaining, separate chaining.

Aggregate child (... is a part of or used in me.)
load factor.

See also open addressing.

Note: Any searchable data structure may be used instead of a linked list, but it is usually better to expand the hash table, thus lowering the load factor, and use a simple collision resolution mechanism, like the linked list.
