Detailed Description

template<class K, class HashFunc = FNV1aHashFunc<K>>
class nctl::HashSetList< K, HashFunc >

A template based hashset implementation with separate chaining and list head cell.

Member Function Documentation

find() [1/2]

template<class K , class HashFunc >

K * nctl::HashSetList< K, HashFunc >::find

(

const K &

key

)

Checks whether an element is in the hashSet or not.

Note

Prefer this method if copying T is expensive, but always check the validity of returned pointer.

find() [2/2]

template<class K , class HashFunc >

const K * nctl::HashSetList< K, HashFunc >::find

(

const K &

key

)

const

Checks whether an element is in the hashSet or not (read-only)

Note

Prefer this method if copying T is expensive, but always check the validity of returned pointer.

insert() [1/2]

template<class K , class HashFunc >

bool nctl::HashSetList< K, HashFunc >::insert

(

const K &

key

)

Inserts an element if no other has the same key.

Returns

True if the element has been inserted

insert() [2/2]

template<class K , class HashFunc >

bool nctl::HashSetList< K, HashFunc >::insert

(

K &&

key

)

Moves an element if no other has the same key.

Returns

True if the element has been inserted
