Constructor & Destructor Documentation

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Allocator = std::allocator<std::pair<const _Key, _Tp> >>

std::__debug::map< _Key, _Tp, _Compare, _Allocator >::map	(	const _Compare &	__comp = _Compare(),
		const _Allocator &	__a = _Allocator()
	)			[inline, explicit]

Default constructor creates no elements.

Reimplemented from std::map< _Key, _Tp, _Compare, _Allocator >.

Definition at line 80 of file map.h.

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Allocator = std::allocator<std::pair<const _Key, _Tp> >>

template<typename _InputIterator>

std::__debug::map< _Key, _Tp, _Compare, _Allocator >::map	(	_InputIterator	__first,
		_InputIterator	__last,
		const _Compare &	__comp = _Compare(),
		const _Allocator &	__a = _Allocator()
	)			[inline]

Builds a map from a range.

Parameters:

	first	An input iterator.
	last	An input iterator.
	comp	A comparison functor.
	a	An allocator object.

Create a map consisting of copies of the elements from [first,last). This is linear in N if the range is already sorted, and NlogN otherwise (where N is distance(first,last)).

const [inline]

Finds a subsequence matching given key.

Parameters:

x

Key of (key, value) pairs to be located.

Returns:

Pair of read-only (constant) iterators that possibly points to the subsequence matching given key.

This function is equivalent to

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

void std::map< _Key , _Tp , _Compare , _Allocator >::erase	(	iterator	__first,

Erases a [first,last) range of elements from a map.

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 map. 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 responsibilty.

__position

An iterator pointing to the element to be erased.

This function erases an element, pointed to by the given iterator, from a map. 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 responsibilty.

const [inline]

Tries to locate an element in a map.

Parameters:

x

Key of (key, value) pair to be located.

Returns:

Read-only (constant) 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 a constant iterator pointing to the sought after pair. If unsuccessful it returns the past-the-end ( end() ) iterator.

iterator std::map< _Key , _Tp , _Compare , _Allocator >::insert	(	iterator	__position,
		const value_type &	__x
	)			[inline, inherited]

Attempts to insert a std::pair into the map.

Parameters:

	position	An iterator that serves as a hint as to where the pair should be inserted.
	x	Pair to be inserted (see std::make_pair for easy creation of pairs).

Returns:

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

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).

void std::__debug::map< _Key, _Tp, _Compare, _Allocator >::insert	(	_InputIterator	__first,

Template function that attemps to insert a range of elements.

Parameters:

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

Complexity similar to that of the range constructor.

std::pair<iterator, bool> std::__debug::map< _Key, _Tp, _Compare, _Allocator >::insert

(

const value_type &

__x

)

[inline]

Attempts to insert a std::pair into the map.

Parameters:

x

Pair to be inserted (see std::make_pair for easy creation of pairs).

Returns:

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

This function attempts to insert a (key, value) pair into the map. A map relies on unique keys and thus a pair is only inserted if its first element (the key) is not already present in the map.

Insertion requires logarithmic time.

mapped_type& std::map< _Key , _Tp , _Compare , _Allocator >::operator[]

__k

)

[inline, inherited]

Subscript ( [] ) access to map data.

Parameters:

k

The key for which data should be retrieved.

Returns:

A reference to the data of the (key,data) pair.

Allows for easy lookup with the subscript ( [] ) operator. Returns data associated with the key specified in subscript. If the key does not exist, a pair with that key is created using default values, which is then returned.

Lookup requires logarithmic time.

void std::map< _Key , _Tp , _Compare , _Allocator >::swap

(

__x

)

[inline, inherited]

Swaps data with another map.

Parameters:

x

A map of the same element and allocator types.

This exchanges the elements between two maps 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(m1,m2) will feed to this function.
