|

* Implementation of an hash map using open addressing with robin hood with backshift delete to resolve collisions.
|
||||
*
|
||||
* The particularity of this hash map is that it remembers the order in which the elements were added and
|
||||
* provide a way to access the structure which stores these values through the 'values_container()' method.
|
||||
* The used container is defined by ValueTypeContainer, by default a std::deque is used (grows faster) but
|
||||
* a std::vector may be used. In this case the map provides a 'data()' method which give a direct access
|
||||
* to the memory used to store the values (which can be useful to communicate with C API's).
|
||||
*
|
||||
* The Key and T must be copy constructible and/or move constructible. To use `unordered_erase` they both
|
||||
* must be swappable.
|
||||
*
|
||||
* The behaviour of the hash map is undefined if the destructor of Key or T throws an exception.
|
||||
*
|
||||
* By default the maximum size of a map is limited to 2^32 - 1 values, if needed this can be changed through
|
||||
* the IndexType template parameter. Using an `uint64_t` will raise this limit to 2^64 - 1 values but each
|
||||
* bucket will use 16 bytes instead of 8 bytes in addition to the space needed to store the values.
|
||||
*
|
||||
* Iterators invalidation:
|
||||
* - clear, operator=, reserve, rehash: always invalidate the iterators (also invalidate end()).
|
||||
* - insert, emplace, emplace_hint, operator[]: when a std::vector is used as ValueTypeContainer
|
||||
* and if size() < capacity(), only end().
|
||||
* Otherwise all the iterators are invalidated if an insert occurs.
|
||||
* - erase, unordered_erase: when a std::vector is used as ValueTypeContainer invalidate the iterator of
|
||||
* the erased element and all the ones after the erased element (including end()).
|
||||
* Otherwise all the iterators are invalidated if an erase occurs.

|

* Implementation of an hash set using open addressing with robin hood with backshift delete to resolve collisions.
|
||||
*
|
||||
* The particularity of this hash set is that it remembers the order in which the elements were added and
|
||||
* provide a way to access the structure which stores these values through the 'values_container()' method.
|
||||
* The used container is defined by ValueTypeContainer, by default a std::deque is used (grows faster) but
|
||||
* a std::vector may be used. In this case the set provides a 'data()' method which give a direct access
|
||||
* to the memory used to store the values (which can be useful to communicate with C API's).
|
||||
*
|
||||
* The Key must be copy constructible and/or move constructible. To use `unordered_erase` it also must be swappable.
|
||||
*
|
||||
* The behaviour of the hash set is undefined if the destructor of Key throws an exception.
|
||||
*
|
||||
* By default the maximum size of a set is limited to 2^32 - 1 values, if needed this can be changed through
|
||||
* the IndexType template parameter. Using an `uint64_t` will raise this limit to 2^64 - 1 values but each
|
||||
* bucket will use 16 bytes instead of 8 bytes in addition to the space needed to store the values.
|
||||
*
|
||||
* Iterators invalidation:
|
||||
* - clear, operator=, reserve, rehash: always invalidate the iterators (also invalidate end()).
|
||||
* - insert, emplace, emplace_hint, operator[]: when a std::vector is used as ValueTypeContainer
|
||||
* and if size() < capacity(), only end().
|
||||
* Otherwise all the iterators are invalidated if an insert occurs.
|
||||
* - erase, unordered_erase: when a std::vector is used as ValueTypeContainer invalidate the iterator of
|
||||
* the erased element and all the ones after the erased element (including end()).
|
||||
* Otherwise all the iterators are invalidated if an erase occurs.
