## Detailed Description

### template<typename Key, typename Mapped, typename Hash_Fn, typename Eq_Fn, typename _Alloc, bool Store_Hash, typename Comb_Hash_Fn, typename Resize_Policy>
class __gnu_pbds::detail::cc_ht_map< Key, Mapped, Hash_Fn, Eq_Fn, _Alloc, Store_Hash, Comb_Hash_Fn, Resize_Policy >

A collision-chaining hash-based container.

Template Parameters

  Key | Key type.
  Mapped | Map type.
  Hash_Fn | Hashing functor. Default is __gnu_cxx::hash.
  Eq_Fn | Equal functor. Default std::equal_to<Key>
  _Alloc | Allocator type.
  Store_Hash | If key type stores extra metadata. Defaults to false.
  Comb_Hash_Fn | Combining hash functor. If Hash_Fn is not null_type, then this is the ranged-hash functor; otherwise, this is the range-hashing functor. XXX(See Design::Hash-Based Containers::Hash Policies.) Default direct_mask_range_hashing.
  Resize_Policy | Resizes hash. Defaults to hash_standard_resize_policy, using hash_exponential_size_policy and hash_load_check_resize_trigger.

Bases are: detail::hash_eq_fn, Resize_Policy, detail::ranged_hash_fn, detail::types_traits. (Optional: detail::debug_map_base.)
