Detailed Description

template<class KEY, class COMPARATOR = std::less<KEY>, class ALLOCATOR = allocator<KEY>>
class bsl::set< KEY, COMPARATOR, ALLOCATOR >

This class template implements a value-semantic container type holding an ordered sequence of unique keys (of the template parameter type, KEY).

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 .

◆ set() [1/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set ( )

inline

Create an empty set. Optionally specify a comparator used to order keys 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 and basicAllocator is not supplied, the currently installed default allocator is used.

Note: Note that a bslma::Allocator * can be supplied for basicAllocator if the type ALLOCATOR is bsl::allocator (the default).

	)

inlineexplicit

◆ set() [3/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set ( const ALLOCATOR & basicAllocator )

inlineexplicit

Create an empty set that uses the specified basicAllocator to supply memory. Use a default-constructed object of the (template parameter) type COMPARATOR to order the keys contained in this set.

Note: Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) type ALLOCATOR is bsl::allocator (the default).

◆ set() [4/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set ( const set< KEY, COMPARATOR, ALLOCATOR > & original )

inline

Create a set having the same value as the specified original object. Use a copy of original.key_comp() to order the keys contained in this set. 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) type KEY be copy-insertable into this set (see {Requirements on KEY}).

◆ set() [5/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set ( BloombergLP::bslmf::MovableRef< set< KEY, COMPARATOR, ALLOCATOR > > original )

inline

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

◆ set() [6/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set	(	const set< KEY, COMPARATOR, ALLOCATOR > &	original,
		const typename type_identity< ALLOCATOR >::type &	basicAllocator
	)

inline

Create a set 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 keys contained in this set. This method requires that the (template parameter) type KEY be copy-insertable into this set (see {Requirements on KEY}).

Note: Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) type ALLOCATOR is bsl::allocator (the default).

◆ set() [7/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set	(	BloombergLP::bslmf::MovableRef< set< KEY, COMPARATOR, ALLOCATOR > >	original,
		const typename type_identity< ALLOCATOR >::type &	basicAllocator
	)

inline

Create a set 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 set 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 keys contained in this set. This method requires that the (template parameter) type KEY be move-insertable into this set (see {Requirements on KEY}).

Note: Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) type ALLOCATOR is bsl::allocator (the default).

◆ set() [8/11]

template<class KEY , class COMPARATOR , class ALLOCATOR >

template<class INPUT_ITERATOR >

bsl::set< KEY, COMPARATOR, ALLOCATOR >::set	(	INPUT_ITERATOR	first,
		INPUT_ITERATOR	last,
		const COMPARATOR &	comparator = `COMPARATOR()`,
		const ALLOCATOR &	basicAllocator = `ALLOCATOR()`
	)

inline

Create a set, and insert each value_type object in the sequence starting at the specified first element, and ending immediately before the specified last element, ignoring those keys having a value equivalent to that which appears earlier in the sequence. Optionally specify a comparator used to order keys 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 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 set, where i is a dereferenceable iterator in the range [first .. last) (see {Requirements on KEY}).

Precondition: 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: Note that a bslma::Allocator * can be supplied for basicAllocator if the type ALLOCATOR is bsl::allocator (the default).

	)

inline

Create a set having the (value_type) values obtained from the specified range. Ignore those those objects having a key equivalent to that which appears earlier in the sequence. 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 values obtained from range are ordered according tocomparator, then this operation hasO[N] complexity, whereNis the number of values in therange; otherwise, this operation hasO[N * log(N)]` complexity.

Note: Note that RANGE must meet the requirements of an input range and the values from range must have a type matching or convertible to value_type.

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_move_assignment , and return a reference providing modifiable access to this object. The contents of rhs are moved (in constant time) to this set if get_allocator() == rhs.get_allocator() (after accounting for the aforementioned trait); otherwise, all elements in this set are either destroyed or move-assigned to and each additional element in rhs is move-inserted into this set. rhs is left in a valid but unspecified state, and if an exception is thrown, *this is left in a valid but unspecified state. This method requires that the (template parameter) type KEY be move-assignable and move-insertable into this set (see {Requirements on KEY}). Return an iterator providing modifiable access to the first value_type object in the ordered sequence of value_type objects maintained by this set, or the end iterator if this set is empty.

◆ cbegin()

template<class KEY , class COMPARATOR , class ALLOCATOR >

set< KEY, COMPARATOR, ALLOCATOR >::const_iterator bsl::set< KEY, COMPARATOR, ALLOCATOR >::cbegin ( ) const

Return the number of value_type objects within this set that are equivalent to the specified key.

Note: Note that since a set maintains unique keys, the returned value will be either 0 or 1.

Note: implemented inline due to Sun CC compilation error.

inline

Return the number of value_type objects within this set that are equivalent to the specified key.

Note: Note that although a set maintains unique keys, the returned value can be other than 0 or 1, because a transparent comparator may have been supplied that provides a different (but compatible) partitioning of keys for LOOKUP_KEY as the comparisons used to order the keys in the set.

Note: implemented inline due to Sun CC compilation error.

◆ crbegin()

Insert into this set a newly created value_type object, constructed by forwarding get_allocator() (if required) and the specified (variable number of) arguments to the corresponding constructor of value_type, if a key equivalent to such a value does not already exist in this set; otherwise, this method has no effect (other than possibly creating a temporary value_type object). Return a pair whose first member is an iterator referring to the (possibly newly created and inserted) object in this set whose value is equivalent to that of an object constructed from arguments, and whose second member is true if a new value was inserted, and false if an equivalent key was already present. This method requires that the (template parameter) type KEY be emplace-constructible from arguments (see {Requirements on KEY}).

template<class... Args>

set< KEY, COMPARATOR, ALLOCATOR >::iterator bsl::set< KEY, COMPARATOR, ALLOCATOR >::emplace_hint	(	const_iterator	hint,

	)

inline

Insert into this set a newly created value_type object, constructed by forwarding get_allocator() (if required) and the specified (variable number of) arguments to the corresponding constructor of value_type, (in amortized constant time if the specified hint is a valid immediate successor to the value_type object constructed from arguments), if a key equivalent to such a value does not already exist in this set; otherwise, this method has no effect (other than possibly creating a temporary value_type object). Return an iterator referring to the (possibly newly created and inserted) object in this set whose value is equivalent to that of an object constructed from arguments. If hint is not a valid immediate successor to the value_type object implied by arguments, this operation has O[log(N)] complexity where N is the size of this set. This method requires that the (template parameter) type KEY be emplace-constructible from arguments (see {Requirements on KEY}).

Precondition: The behavior is undefined unless hint is an iterator in the range [begin() .. end()] (both endpoints included).

Return a pair of iterators providing modifiable access to the sequence of value_type objects in this set that are equivalent to the specified key, where the first iterator is positioned at the start of the sequence, and the second is positioned one past the end of the sequence. The first returned iterator will be lower_bound(key); the second returned iterator will be upper_bound(key); and, if this set contains no value_type objects equivalent to key, then the two returned iterators will have the same value.

Note: Note that since a set maintains unique keys, the range will contain at most one element.

Return a pair of iterators providing modifiable access to the sequence of value_type objects in this set that are equivalent to the specified key, where the first iterator is positioned at the start of the sequence, and the second is positioned one past the end of the sequence. The first returned iterator will be lower_bound(key); the second returned iterator will be upper_bound(key); and, if this set contains no value_type objects equivalent to key, then the two returned iterators will have the same value.

Note: Note that although a set maintains unique keys, the range may contain more than one element, because a transparent comparator may have been supplied that provides a different (but compatible) partitioning of keys for LOOKUP_KEY as the comparisons used to order the keys in the set.

Member Data Documentation

◆ clear

template<class KEY , class COMPARATOR , class ALLOCATOR >

void bsl::set< KEY, COMPARATOR, ALLOCATOR >::clear

inline

Exchange the value and comparator of this object with those of the specified other object; also exchange the allocator of this object with that of other if the (template parameter) type ALLOCATOR has the propagate_on_container_swap trait, and do not modify either allocator otherwise. This method provides the no-throw exception-safety guarantee if and only if the (template parameter) type COMPARATOR provides a no-throw swap operation, and provides the basic exception-safety guarantee otherwise; if an exception is thrown, both objects are left in valid but unspecified states. This operation has O[1] complexity if either this object was created with the same allocator as other or ALLOCATOR has the propagate_on_container_swap trait; otherwise, it has O[n + m] complexity, where n and m are the number of elements in this object and other, respectively.

Note: Note that this methods support for swapping objects created with different allocators when ALLOCATOR` does not have the propagate_on_container_swap trait is a departure from the C++ Standard. Remove all entries from this set.; Note that the set is empty after this call, but allocated memory may be retained for future use.
