Because of its options,NSHashTableis not a set because it can behave differently (for example, if pointer equality is specified twoisEqual:strings will both be entered). When configuring hash tables, note that only the options listed inNSHashTableOptionsguarantee that the rest of the API will...
I just wanted a simple and straightforward hash table implementation that I could drop into my own C-based projects on whatever platform. I haven't implemented one of these before, so it may be super naive, but it does appear to work pretty well. ...

This class implements theSetinterface, backed by a hash table (actually aHashMapinstance). It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. This class permits thenullelement. ...

Hash table and linked list implementation of theSetinterface, with predictable iteration order. This implementation differs fromHashSetin that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is the order in which elements ...
The System.Collections.Hashtable Class The .NET Framework Base Class Library includes an implementation of a hash table in theHashtableclass. When adding an item to the Hashtable, you must provide not only the item, but the unique key by which the item is accessed. Both the key and item...

only retrieve the full key data when the hashes match. If there are many exact collisions, then many unsuccessful retrieval of key data will be performed, wasting a lot of I/O. This metric depends only on the hash function, not on the hash table algorithm, which is why it is not ...
