The concurrent_unordered_multiset class is an concurrency-safe container that controls a varying-length sequence of elements of type _Key_type. The sequence is represented in a way that enables concurrency-safe append, element access, iterator access and iterator traversal operations.

template <
   typename _Key_type,
   typename _Hasher = std::tr1::hash<_Key_type>,
   typename _Key_equality = std::equal_to<_Key_type>,
   typename _Allocator_type = std::allocator<_Key_type>

Parameters

_Key_type
The key type.
_Hasher
The hash function object type. This argument is optional and the default value is std::tr1::hash<_Key_type**>**.
_Key_equality
The equality comparison function object type. This argument is optional and the default value is std::equal_to<_Key_type**>**.
_Allocator_type
The type that represents the stored allocator object that encapsulates details about the allocation and deallocation of memory for the concurrent vector. This argument is optional and the default value is std::allocator<_Key_type**>**.
