Detailed Description

template<class KEY, class VALUE, class COMPARATOR = std::less<KEY>, class ALLOCATOR = allocator<pair<const KEY, VALUE> >>
class bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >

This class template implements a value-semantic container type holding an ordered sequence of key-value pairs having possibly duplicate keys that provide a mapping from keys (of the template parameter type, KEY) 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
  • is alias-safe
  • is const thread-safe For terminology see bsldoc_glossary .

See bslstl_multimap

bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( const COMPARATOR &  comparator,
const ALLOCATOR &  basicAllocator = ALLOCATOR() 
)
inlineexplicit

Create an empty multimap. Optionally specify a comparator used to order key-value pairs contained in this object. If comparator is not supplied, a default-constructed object of the (template parameter) type COMPARATOR 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.

◆ multimap() [3/9]

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( const ALLOCATOR &  basicAllocator)
inlineexplicit

Create an empty multimap that uses the specified basicAllocator to supply memory. Use a default-constructed object of the (template parameter) type COMPARATOR to order the key-value pairs contained in this multimap. Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) ALLOCATOR is bsl::allocator (the default).

◆ multimap() [4/9]

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( const multimap< KEY, VALUE, COMPARATOR, ALLOCATOR > &  original)
inline

Create a multimap having the same value as the specified original object. Use a copy of original.key_comp() to order the key-value pairs contained in this multimap. 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 multimap (see {Requirements on KEY and VALUE}).

◆ multimap() [5/9]

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( BloombergLP::bslmf::MovableRef< multimap< KEY, VALUE, COMPARATOR, ALLOCATOR > >  original)
inline

Create a multimap having the same value as the specified original object by moving (in constant time) the contents of original to the new multimap. Use a copy of original.key_comp() to order the key-value pairs contained in this multimap. The allocator associated with original is propagated for use in the newly-created multimap. original is left in a valid but unspecified state.

◆ multimap() [6/9]

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( const multimap< KEY, VALUE, COMPARATOR, ALLOCATOR > &  original,
const typename type_identity< ALLOCATOR >::type &  basicAllocator 
)
inline

Create a multimap having the same value as the specified original object that uses the specified basicAllocator to supply memory. Use a copy of original.key_comp() to order the key-value pairs contained in this multimap. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this multimap (see {Requirements on KEY and VALUE}). Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) ALLOCATOR is bsl::allocator (the default).

◆ multimap() [7/9]

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( BloombergLP::bslmf::MovableRef< multimap< KEY, VALUE, COMPARATOR, ALLOCATOR > >  original,
const typename type_identity< ALLOCATOR >::type &  basicAllocator 
)
inline

Create a 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 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.key_comp() to order the key-value pairs contained in this multimap. This method requires that the (template parameter) types KEY and VALUE both be move-insertable into this multimap (see {Requirements on KEY and VALUE}). Note that a 'bslma::Allocator *can be supplied forbasicAllocator' if the (template parameter) ALLOCATOR is bsl::allocator (the default).

◆ multimap() [8/9]

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
template<class INPUT_ITERATOR >
bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::multimap ( INPUT_ITERATOR  first,
INPUT_ITERATOR  last,
const COMPARATOR &  comparator = COMPARATOR(),
const ALLOCATOR &  basicAllocator = ALLOCATOR() 
)
inline

Create a 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 a comparator used to order key-value pairs contained in this object. If comparator is not supplied, a default-constructed object of the (template parameter) type COMPARATOR 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. If the sequence first to last is ordered according to comparator, then this operation has O[N] complexity, where N is the number of elements between first and last; otherwise, this operation has O[N * log(N)] complexity. 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 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.

inline

Remove from this multimap the value_type object at the specified position, and return an iterator referring to the element immediately following the removed element, or to the past-the-end position if the removed element was the last element in the sequence of elements maintained by this multimap. This method invalidates only iterators and references to the removed element and previously saved values of the end() iterator. The behavior is undefined unless position refers to a value_type object in this multimap.

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::iterator bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::insert ( const value_type value)
inline

Insert the specified value into this multimap. If a range containing elements equivalent to value already exists, insert the value at the end of that range. Return an iterator referring to the newly inserted value_type object. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this multimap (see {Requirements on KEY and VALUE}).

multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::iterator bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::insert ( const_iterator  hint,
const value_type value 
)
inline

Insert the specified value into this multimap (in amortized constant time if the specified hint is a valid immediate successor to the key of value). Return an iterator referring to the newly inserted value_type object. If hint is not a valid immediate successor to the key of value, this operation has O[log(N)] complexity, where N is the size of this multimap. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this multimap (see {Requirements on KEY and VALUE}). The behavior is undefined unless hint is an iterator in the range [begin() .. end()] (both endpoints included).

◆ insert() [5/5]

template<class INPUT_ITERATOR >
void bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::insert ( INPUT_ITERATOR  first,
INPUT_ITERATOR  last 
)
inline

Insert into this 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 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 an iterator providing modifiable access to the first (i.e., ordered least) value_type object in this multimap whose key is greater-than or equal-to the specified key, and the past-the-end iterator if this multimap does not contain a value_type object whose key is greater-than or equal-to key. Note that this function returns the first position before which a value_type object having an equivalent key could be inserted into the ordered sequence maintained by this multimap, while preserving its ordering.

Note: implemented inline due to Sun CC compilation error.

multimap< KEY, VALUE, COMPARATOR, ALLOCATOR > & bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::operator= ( const multimap< KEY, VALUE, COMPARATOR, ALLOCATOR > &  rhs)
inline

Assign to this object the value and 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 multimap (see {Requirements on KEY and VALUE}).

Member Data Documentation

◆ clear

template<class KEY , class VALUE , class COMPARATOR , class ALLOCATOR >
void bsl::multimap< KEY, VALUE, COMPARATOR, ALLOCATOR >::clear
inline

Remove from this multimap the value_type objects starting at the specified first position up to, but including the specified last position, and return last. This method invalidates only iterators and references to the removed element and previously saved values of the end() iterator. The behavior is undefined unless first and last either refer to elements in this multimap or are the end iterator, and the first position is at or before the last position in the ordered sequence provided by this container. Remove all entries from this multimap. Note that the multimap is empty after this call, but allocated memory may be retained for future use.
