Returns a read/write iterator that points to the first element in the set. Iteration is done in ascending order according to the keys.
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| 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 responsibilty.
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| bool std::set< _Key, _Compare, _Alloc >::empty | ( | ) | const [inline] |
| iterator std::set< _Key, _Compare, _Alloc >::end | ( | ) | const [inline] |

| x | Key to be located. |
std::make_pair(c.lower_bound(val), c.upper_bound(val))
This function probably only makes sense for multisets.
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| void std::set< _Key, _Compare, _Alloc >::erase | ( | iterator | __first, | |
| iterator | __last | |||
| ) | [inline] |
Erases a [first,last) range of elements from a set.
| first | Iterator pointing to the start of the range to be erased. | |
| last | Iterator pointing to the end of the range to be erased. |
| size_type std::set< _Key, _Compare, _Alloc >::erase | ( | const key_type & | __x | ) | [inline] |
Erases elements according to the provided key.
| x | Key of element to be erased. |
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| void std::set< _Key, _Compare, _Alloc >::erase | ( | iterator | __position | ) | [inline] |

| position | An iterator pointing to the element to be erased. |
| iterator std::set< _Key, _Compare, _Alloc >::find | ( | const key_type & | __x | ) | [inline] |
Tries to locate an element in a set.

| void std::set< _Key, _Compare, _Alloc >::insert | ( | _InputIterator | __first, | |
| _InputIterator | __last | |||
| ) | [inline] |
A template function that attemps to insert a range of elements.
| first | Iterator pointing to the start of the range to be inserted. | |
| last | Iterator pointing to the end of the range. |
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| iterator std::set< _Key, _Compare, _Alloc >::insert | ( | iterator | __position, | |
| const value_type & | __x | |||
| ) | [inline] |
Attempts to insert an element into the set.
| position | An iterator that serves as a hint as to where the element should be inserted. | |
| x | Element to be inserted. |
See http://gcc.gnu.org/onlinedocs/libstdc++/23_containers/howto.html#4 for more on "hinting".
Insertion requires logarithmic time (if the hint is not taken).
| std::pair<iterator,bool> std::set< _Key, _Compare, _Alloc >::insert | ( | const value_type & | __x | ) | [inline] |
Attempts to insert an element into the set.
| x | Element to be inserted. |
Insertion requires logarithmic time.

Finds the beginning of a subsequence matching given key.
| x | Key to be located. |

Set assignment operator.
| x | A set of identical element and allocator types. |
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| reverse_iterator std::set< _Key, _Compare, _Alloc >::rbegin | ( | ) | const [inline] |
Returns a read/write reverse iterator that points to the last element in the set. Iteration is done in descending order according to the keys.
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| reverse_iterator std::set< _Key, _Compare, _Alloc >::rend | ( | ) | const [inline] |
Returns a read-only (constant) reverse iterator that points to the last pair in the map. Iteration is done in descending order according to the keys.
Reimplemented in std::__debug::set< _Key, _Compare, _Allocator >.
| void std::set< _Key, _Compare, _Alloc >::swap | ( | set< _Key, _Compare, _Alloc > & | __x | ) | [inline] |
Swaps data with another set.
| x | A set of the same element and allocator types. |
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.
