Detailed Description

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> class std::set< _Key, _Compare, _Alloc >

A standard container made up of unique keys, which can be retrieved in logarithmic time.

Meets the requirements of a container, a reversible container, and an associative container (using unique keys).

Sets support bidirectional iterators.

Parameters:

Key Type of key objects.
Compare Comparison function object type, defaults to less<Key>.
Alloc Allocator type, defaults to allocator<Key>.

The private tree data is declared exactly the same way for set and multiset; the distinction is made entirely in how the tree functions are called (*_unique versus *_equal, same as the standard).

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> void std::set< _Key, _Compare, _Alloc >::clear () [inline]Erases all elements in a set. Note that this function only erases the elements, and that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Definition at line 515 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> size_type std::set< _Key, _Compare, _Alloc >::count (const key_type & __x) const [inline]

Finds the number of elements. Parameters:

x Element to located.

Returns:

Number of elements with specified key.

This function only makes sense for multisets; for set the result will either be 0 (not present) or 1 (present).

Definition at line 529 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> reverse_iterator std::set< _Key, _Compare, _Alloc >::crbegin () const [inline]Returns a read-only (constant) iterator that points to the last element in the set.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> std::pair<iterator, iterator> std::set< _Key, _Compare, _Alloc >::equal_range (const key_type & __x) [inline]

Finds a subsequence matching given key. Parameters:

x Key to be located.

Returns:

Pair of iterators that possibly points to the subsequence matching given key.

This function is equivalent to

     std::make_pair(c.lower_bound(val),
                    c.upper_bound(val))
 
 

 (but is faster than making the calls separately).

This function probably only makes sense for multisets.

Finds a subsequence matching given key. Parameters:

x Key to be located.

Returns:

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> void std::set< _Key, _Compare, _Alloc >::erase (iterator __position) [inline]

Erases an element from a set. Parameters:

position An iterator pointing to the element to be erased.

This function erases an element, pointed to by the given iterator, from a set. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Definition at line 475 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> size_type std::set< _Key, _Compare, _Alloc >::erase (const key_type & __x) [inline]

Erases elements according to the provided key. Parameters:

x Key of element to be erased.

Returns:

The number of elements erased.

This function erases all the elements located by the given key from a set. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Definition at line 490 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> void std::set< _Key, _Compare, _Alloc >::erase (iterator __first, iterator __last) [inline]

Erases a [first,last) range of elements from a set. Parameters:

first Iterator pointing to the start of the range to be erased.
last Iterator pointing to the end of the range to be erased.

This function erases a sequence of elements from a set. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Definition at line 505 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> iterator std::set< _Key, _Compare, _Alloc >::find (const key_type & __x) [inline]

Tries to locate an element in a set. Parameters:

x Element to be located.

Returns:

Iterator pointing to sought-after element, or end() if not found.

This function takes a key and tries to locate the element with which the key matches. If successful the function returns an iterator pointing to the sought after element. If unsuccessful it returns the past-the-end ( end() ) iterator.

Definition at line 547 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> const_iterator std::set< _Key, _Compare, _Alloc >::find (const key_type & __x) const [inline]

Tries to locate an element in a set. Parameters:

x Element to be located.

Returns:

Iterator pointing to sought-after element, or end() if not found.

This function takes a key and tries to locate the element with which the key matches. If successful the function returns an iterator pointing to the sought after element. If unsuccessful it returns the past-the-end ( end() ) iterator.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> allocator_type std::set< _Key, _Compare, _Alloc >::get_allocator () const [inline]

Returns the allocator object with which the set was constructed.

Definition at line 282 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> std::pair<iterator, bool> std::set< _Key, _Compare, _Alloc >::insert (const value_type & __x) [inline]

Attempts to insert an element into the set. Parameters:

x Element to be inserted.

Returns:

A pair, of which the first element is an iterator that points to the possibly inserted element, and the second is a bool that is true if the element was actually inserted.

This function attempts to insert an element into the set. A set relies on unique keys and thus an element is only inserted if it is not already present in the set.

Insertion requires logarithmic time.

Definition at line 408 of file stl_set.h.

References std::pair< _T1, _T2 >::first, and std::pair< _T1, _T2 >::second.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> iterator std::set< _Key, _Compare, _Alloc >::insert (iterator __position, const value_type & __x) [inline]

Attempts to insert an element into the set. Parameters:

position An iterator that serves as a hint as to where the element should be inserted.
x Element to be inserted.

Returns:

An iterator that points to the element with key of x (may or may not be the element passed in).

This function is not concerned about whether the insertion took place, and thus does not return a boolean like the single-argument insert() does. Note that the first parameter is only a hint and can potentially improve the performance of the insertion process. A bad hint would cause no gains in efficiency.

For more on 'hinting', see: http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt07ch17.html

Insertion requires logarithmic time (if the hint is not taken).

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> template<typename _InputIterator > void std::set< _Key, _Compare, _Alloc >::insert (_InputIterator __first, _InputIterator __last) [inline]

A template function that attempts to insert a range of elements. Parameters:

first Iterator pointing to the start of the range to be inserted.
last Iterator pointing to the end of the range.

Complexity similar to that of the range constructor.

Definition at line 449 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> void std::set< _Key, _Compare, _Alloc >::insert (initializer_list< value_type > __l) [inline]

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> iterator std::set< _Key, _Compare, _Alloc >::lower_bound (const key_type & __x) [inline]

Finds the beginning of a subsequence matching given key. Parameters:

x Key to be located.

Returns:

Iterator pointing to first element equal to or greater than key, or end().

This function returns the first element of a subsequence of elements that matches the given key. If unsuccessful it returns an iterator pointing to the first element that has a greater value than given key or end() if no such element exists.

Definition at line 568 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> const_iterator std::set< _Key, _Compare, _Alloc >::lower_bound (const key_type & __x) const [inline]

Finds the beginning of a subsequence matching given key. Parameters:

x Key to be located.

Returns:

Iterator pointing to first element equal to or greater than key, or end().

This function returns the first element of a subsequence of elements that matches the given key. If unsuccessful it returns an iterator pointing to the first element that has a greater value than given key or end() if no such element exists.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> set& std::set< _Key, _Compare, _Alloc >::operator= (set< _Key, _Compare, _Alloc > && __x) [inline]

Set move assignment operator. Parameters:

x A set of identical element and allocator types.

The contents of x are moved into this set (without copying). x is a valid, but unspecified set.

Definition at line 242 of file stl_set.h.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> set& std::set< _Key, _Compare, _Alloc >::operator= (initializer_list< value_type > __l) [inline]

Set list assignment operator. Parameters:

l An initializer_list.

This function fills a set with copies of the elements in the initializer list l.

Note that the assignment completely changes the set and that the resulting set's size is the same as the number of elements assigned. Old data may be lost.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> set& std::set< _Key, _Compare, _Alloc >::operator= (const set< _Key, _Compare, _Alloc > & __x) [inline]

Set assignment operator. Parameters:

x A set of identical element and allocator types.

All the elements of x are copied, but unlike the copy constructor, the allocator object is not copied.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> void std::set< _Key, _Compare, _Alloc >::swap (set< _Key, _Compare, _Alloc > && __x) [inline]

Swaps data with another set. Parameters:

x A set of the same element and allocator types.

This exchanges the elements between two sets in constant time. (It is only swapping a pointer, an integer, and an instance of the Compare type (which itself is often stateless and empty), so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(s1,s2) will feed to this function.
