Detailed Description

template<class KEY, class VALUE, class HASH = bsl::hash<KEY>, class EQUAL = bsl::equal_to<KEY>, class ALLOCATOR = bsl::allocator<bsl::pair<const KEY, VALUE> >>
class bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >

This class template implements a value-semantic container type holding a collection of (possibly equivalent) keys (of the template parameter type KEY), each mapped to their associated values (of another template parameter type VALUE).

This class:

supports a complete set of value-semantic operations
- except for BDEX serialization
is exception-neutral (agnostic except for the at method)
is alias-safe
is const thread-safe For terminology see bsldoc_glossary .

Create an empty unordered multimap. Optionally specify an initialNumBuckets indicating the minimum initial size of the array of buckets of this container. If initialNumBuckets is not supplied, a single empty bucket is used. Optionally specify a hashFunction used to generate the hash values for the keys contained in this unordered multimap. If hashFunction is not supplied, a default-constructed object of the (template parameter) type HASH is used. Optionally specify a key-equivalence functor keyEqual used to verify that two keys are equivalent. If keyEqual is not supplied, a default-constructed object of the (template parameter) type EQUAL is used. Optionally specify a basicAllocator used to supply memory. If basicAllocator is not supplied, a default-constructed object of the (template parameter) type ALLOCATOR is used. If the type ALLOCATOR is bsl::allocator (the default), then basicAllocator, if supplied, shall be convertible to bslma::Allocator *. If the type ALLOCATOR is bsl::allocator and basicAllocator is not supplied, the currently installed default allocator is used.

bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::unordered_multimap ( const unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR > & original )

inline

Create an unordered multimap having the same value as the specified original object. Use a copy of original.hash_function() to generate hash values for the keys contained in this unordered multimap. Use a copy of original.key_eq() to verify that two keys are equivalent. Use the allocator returned by bsl::allocator_traits<ALLOCATOR>:: select_on_container_copy_construction(original.get_allocator()) to allocate memory. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this unordered multimap (see {Requirements on KEY and VALUE}).

bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::unordered_multimap ( BloombergLP::bslmf::MovableRef< unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR > > original )

inline

Create an unordered multimap having the same value as the specified original object by moving (in constant time) the contents of original to the new unordered multimap. Use a copy of original.hash_function() to generate hash values for the keys contained in this unordered multimap. Use a copy of original.key_eq() to verify that two keys are equivalent. The allocator associated with original is propagated for use in the newly-created unordered multimap. original is left in a valid but unspecified state.

Create an unordered multimap having the same value as the specified original object that uses the specified basicAllocator to supply memory. Use a copy of original.hash_function() to generate hash values for the keys contained in this unordered multimap. Use a copy of original.key_eq() to verify that two keys are equivalent. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this unordered multimap (see {Requirements on KEY and VALUE}). Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) type ALLOCATOR is bsl::allocator (the default).

	)

inline

Create an unordered multimap having the same value as the specified original object that uses the specified basicAllocator to supply memory. The contents of original are moved (in constant time) to the new unordered multimap if basicAllocator == original.get_allocator(), and are move-inserted (in linear time) using basicAllocator otherwise. original is left in a valid but unspecified state. Use a copy of original.hash_function() to generate hash values for the keys contained in this unordered multimap. Use a copy of original.key_eq() to verify that two keys are equivalent. This method requires that the (template parameter) types KEY and VALUE both be move-insertable into this unordered multimap (see {Requirements on KEY and VALUE}).

inline

Create an unordered multimap, and insert each value_type object in the sequence starting at the specified first element, and ending immediately before the specified last element. Optionally specify an initialNumBuckets indicating the minimum initial size of the array of buckets of this container. If initialNumBuckets is not supplied, a single empty bucket is used if first and last denote an empty range, and an unspecified number of buckets is used otherwise. Optionally specify a hashFunction used to generate hash values for the keys contained in this unordered multimap. If hashFunction is not supplied, a default-constructed object of (template parameter) type HASH is used. Optionally specify a key-equivalence functor keyEqual used to verify that two keys are equivalent. If keyEqual is not supplied, a default-constructed object of (template parameter) type EQUAL is used. Optionally specify a basicAllocator used to supply memory. If basicAllocator is not supplied, a default-constructed object of the (template parameter) type ALLOCATOR is used. If the type ALLOCATOR is bsl::allocator and basicAllocator is not supplied, the currently installed default allocator is used to supply memory. The (template parameter) type INPUT_ITERATOR shall meet the requirements of an input iterator defined in the C++11 standard [24.2.3] providing access to values of a type convertible to value_type, and value_type must be emplace-constructible from *i into this unordered multimap, where i is a dereferenceable iterator in the range [first .. last) (see {Requirements on KEY and VALUE}). The behavior is undefined unless first and last refer to a sequence of valid values where first is at a position at or before last. Note that a bslma::Allocator * can be supplied for basicAllocator if the type ALLOCATOR is bsl::allocator (the default).

Remove from this unordered multimap all value_type objects with a key equivalent to the specified key, if such exist, and return the number of objects erased; otherwise, if there are no value_type objects with a key equivalent to key, return 0 with no other effect. This method invalidates only iterators and references to the removed element and previously saved values of the end() iterator, and preserves the relative order of the elements not removed.

inline

Insert the specified value into this unordered multimap (in constant time if the specified hint refers to an element in this container with a key equivalent to the key of value), and return an iterator referring to the newly inserted value_type object. If hint does not refer to an element in this container with a key equivalent to the key of value, this operation has worst case O[N] and average case constant-time complexity, where N is the size of this unordered multimap. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this unordered multimap (see {Requirements on KEY and VALUE}).

template<class INPUT_ITERATOR >

void bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::insert	(	INPUT_ITERATOR	first,
		INPUT_ITERATOR	last
	)

Insert into this unordered multimap the value of each value_type object in the range starting at the specified first iterator and ending immediately before the specified last iterator. The (template parameter) type INPUT_ITERATOR shall meet the requirements of an input iterator defined in the C++11 standard [24.2.3] providing access to values of a type convertible to value_type, and value_type must be emplace-constructible from *i into this unordered multimap, where i is a dereferenceable iterator in the range [first .. last) (see {Requirements on KEY and VALUE}). The behavior is undefined unless first and last refer to a sequence of valid values where first is at a position at or before last.

Return (a copy of) the key-equivalence binary functor that returns true if the value of two key_type objects are equivalent, and false otherwise.

◆ load_factor()

template<class KEY , class VALUE , class HASH , class EQUAL , class ALLOCATOR >

float bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::load_factor ( ) const

inline

Return the current ratio between the size of this container and the number of buckets. The load factor is a measure of how full the container is, and a higher load factor typically leads to an increased number of collisions, thus resulting in a loss of performance.

◆ max_bucket_count()

template<class KEY , class VALUE , class HASH , class EQUAL , class ALLOCATOR >

unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::size_type bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::max_bucket_count ( ) const

inline

Return a theoretical upper bound on the largest number of buckets that this container could possibly manage. Note that there is no guarantee that the unordered multimap can successfully grow to the returned size, or even close to that size without running out of resources.

◆ max_load_factor() [1/2]

template<class KEY , class VALUE , class HASH , class EQUAL , class ALLOCATOR >

float bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::max_load_factor ( ) const

inline

Return the maximum load factor allowed for this container. Note that if an insert operation would cause the load factor to exceed the max_load_factor, that same insert operation will increase the number of buckets and rehash the elements of the container into those buckets (see rehash).

◆ max_load_factor() [2/2]

template<class KEY , class VALUE , class HASH , class EQUAL , class ALLOCATOR >

void bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::max_load_factor ( float newLoadFactor )

inline

Assign to this object the value, hash function, and key-equivalence comparator of the specified rhs object, propagate to this object the allocator of rhs if the ALLOCATOR type has trait propagate_on_container_copy_assignment, and return a reference providing modifiable access to this object. If an exception is thrown, *this is left in a valid but unspecified state. This method requires that the (template parameter) types KEY and VALUE both be copy-assignable and copy-insertable into this unordered multimap (see {Requirements on KEY and VALUE}).

◆ rehash()

template<class KEY , class VALUE , class HASH , class EQUAL , class ALLOCATOR >

void bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::rehash ( size_type numBuckets )

inline

Change the size of the array of buckets maintained by this container to the specified numBuckets, and redistribute all the contained elements into the new sequence of buckets, according to their hash values. Note that this operation has no effect if rehashing the elements into numBuckets would cause this unordered multimap to exceed its max_load_factor.

◆ reserve()

template<class KEY , class VALUE , class HASH , class EQUAL , class ALLOCATOR >

void bsl::unordered_multimap< KEY, VALUE, HASH, EQUAL, ALLOCATOR >::reserve ( size_type numElements )

inline

Increase the number of buckets of this unordered multimap to a quantity such that the ratio between the specified numElements and the new number of buckets does not exceed max_load_factor. Note that this guarantees that, after the reserve, elements can be inserted to grow the container to size() == numElements without rehashing. Also note that memory allocations may still occur when growing the container to size() == numElements. Also note that this operation has no effect if numElements <= size().
