concurrent_unordered_multiset Class

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.

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

_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>.

Name

Description

allocator_type

The type of an allocator for managing storage.

const_iterator

The type of a constant iterator for the controlled sequence.

const_local_iterator

The type of a constant bucket iterator for the controlled sequence.

const_pointer

The type of a constant pointer to an element.

const_reference

The type of a constant reference to an element.

difference_type

The type of a signed distance between two elements.

hasher

The type of the hash function.

iterator

The type of an iterator for the controlled sequence.

key_equal

The type of the comparison function.

key_type

The type of an ordering key.

local_iterator

The type of a bucket iterator for the controlled sequence.

pointer

The type of a pointer to an element.

reference

The type of a reference to an element.

size_type

The type of an unsigned distance between two elements.

value_type

The type of an element.

Name

Description

concurrent_unordered_multiset::concurrent_unordered_multiset Constructor

Overloaded. Constructs a concurrent unordered multiset.

Name

Description

concurrent_unordered_multiset::hash_function Method

Returns the stored hash function object.

concurrent_unordered_multiset::insert Method

Overloaded. Adds elements to the concurrent_unordered_multiset object.

concurrent_unordered_multiset::key_eq Method

The stored equality comparison function object.

concurrent_unordered_multiset::swap Method

Swaps the contents of two concurrent_unordered_multiset objects. This method is not concurrency-safe.

concurrent_unordered_multiset::unsafe_erase Method

Overloaded. Removes elements from the concurrent_unordered_multiset at specified positions. This method is not concurrency-safe.

Name

Description

concurrent_unordered_multiset::operator= Operator

Overloaded. Assigns the contents of another concurrent_unordered_multiset object to this one. This method is not concurrency-safe.
