Detailed Description

template<typename _Tp, typename _Alloc = allocator<_Tp>>
class _GLIBCXX_STD::vector< _Tp, _Alloc >

A standard container which offers fixed time access to individual elements in any order.

Meets the requirements of a container, a reversible container, and a sequence, including the optional sequence requirements with the exception of push_front and pop_front.

In some terminology a vector can be described as a dynamic C-style array, it offers fast and efficient access to individual elements in any order and saves the user from worrying about memory and size allocation. Subscripting ( [] ) access is also provided as with C-style arrays.

Constructor & Destructor Documentation

template<typename _Tp, typename _Alloc = allocator<_Tp>>

_GLIBCXX_STD::vector< _Tp, _Alloc >::vector ( const allocator_type & __a = allocator_type() ) [inline, explicit]

Default constructor creates no elements.

Definition at line 181 of file stl_vector.h.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

_GLIBCXX_STD::vector< _Tp, _Alloc >::vector ( size_type __n,

const value_type & __value,

const allocator_type & __a = allocator_type()

) [inline]

Create a vector with copies of an exemplar element.

Parameters:

n The number of elements to initially create.

value An element to copy.

This constructor fills the vector with n copies of value.
Definition at line 191 of file stl_vector.h.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

_GLIBCXX_STD::vector< _Tp, _Alloc >::vector ( size_type __n ) [inline, explicit]

Create a vector with default elements.

Parameters:

n The number of elements to initially create.

This constructor fills the vector with n copies of a default-constructed element.
Definition at line 205 of file stl_vector.h.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

_GLIBCXX_STD::vector< _Tp, _Alloc >::vector ( const vector< _Tp, _Alloc > & __x ) [inline]

Vector copy constructor.

Parameters:

x A vector of identical element and allocator types.

The newly-created vector uses a copy of the allocation object used by x. All the elements of x are copied, but any extra memory in x (for fast expansion) will not be copied.
Definition at line 219 of file stl_vector.h.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

template<typename _InputIterator>

_GLIBCXX_STD::vector< _Tp, _Alloc >::vector ( _InputIterator __first,

_InputIterator __last,

const allocator_type & __a = allocator_type()

) [inline]

Builds a vector from a range.

Parameters:

first An input iterator.

last An input iterator.

Create a vector consisting of copies of the elements from [first,last).
If the iterators are forward, bidirectional, or random-access, then this will call the elements' copy constructor N times (where N is distance(first,last)) and do no memory reallocation. But if only input iterators are used, then this will do at most 2N calls to the copy constructor, and logN memory reallocations.
Definition at line 241 of file stl_vector.h.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

_GLIBCXX_STD::vector< _Tp, _Alloc >::~vector ( ) [inline]

The dtor only erases the elements, and note 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.

Assigns a range to a vector.

Parameters:

This function fills a vector with copies of the elements in the range [first,last).

template<typename _Tp, typename _Alloc>

vector< _Tp, _Alloc >::iterator _GLIBCXX_STD::vector< _Tp, _Alloc >::erase ( iterator __first,

)

Remove a range of elements.

Parameters:

first Iterator pointing to the first element to be erased.

last Iterator pointing to one past the last element to be erased.

Returns:
An iterator pointing to the element pointed to by last prior to erasing (or end()).
This function will erase the elements in the range [first,last) and shorten the vector accordingly.
Note This operation could be expensive and if it is frequently used the user should consider using std::list. The user is also cautioned 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.

Remove element at given position.

Parameters:

Returns:
An iterator pointing to the next element (or end()).
This function will erase the element at the given position and thus shorten the vector by one.
Note This operation could be expensive and if it is frequently used the user should consider using std::list. The user is also cautioned 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_reference _GLIBCXX_STD::vector< _Tp, _Alloc >::operator[] ( size_type __n ) const [inline]

Subscript access to the data contained in the vector.

Parameters:

n The index of the element for which data should be accessed.

Returns:
Read-only (constant) reference to data.
This operator allows for easy, array-style, data access. Note that data access with this operator is unchecked and out_of_range lookups are not defined. (For checked lookups see at().)

void _GLIBCXX_STD::vector< _Tp, _Alloc >::pop_back ( ) [inline]

Removes last element.
This is a typical stack operation. It shrinks the vector by one.
Note that no data is returned, and if the last element's data is needed, it should be retrieved before pop_back() is called.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

void _GLIBCXX_STD::vector< _Tp, _Alloc >::push_back ( const value_type & __x ) [inline]

Add data to the end of the vector.

Parameters:

x Data to be added.

This is a typical stack operation. The function creates an element at the end of the vector and assigns the given data to it. Due to the nature of a vector this operation can be done in constant time if the vector has preallocated space available.

template<typename _Tp, typename _Alloc>

void _GLIBCXX_STD::vector< _Tp, _Alloc >::reserve ( size_type __n )

Attempt to preallocate enough memory for specified number of elements.

Parameters:

n Number of elements required.

Exceptions:

std::length_error If n exceeds max_size().

This function attempts to reserve enough memory for the vector to hold the specified number of elements. If the number requested is more than max_size(), length_error is thrown.
The advantage of this function is that if optimal code is a necessity and the user can determine the number of elements that will be required, the user can reserve the memory in advance, and thus prevent a possible reallocation of memory and copying of vector data.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

void _GLIBCXX_STD::vector< _Tp, _Alloc >::resize ( size_type __new_size ) [inline]

Resizes the vector to the specified number of elements.

Parameters:

new_size Number of elements the vector should contain.

This function will resize the vector to the specified number of elements. If the number is smaller than the vector's current size the vector is truncated, otherwise the vector is extended and new elements are default-constructed.

template<typename _Tp, typename _Alloc = allocator<_Tp>>

void _GLIBCXX_STD::vector< _Tp, _Alloc >::resize ( size_type __new_size,

Resizes the vector to the specified number of elements.

Parameters:

new_size Number of elements the vector should contain.

x Data with which new elements should be populated.

This function will resize the vector to the specified number of elements. If the number is smaller than the vector's current size the vector is truncated, otherwise the vector is extended and new elements are populated with given data.

void _GLIBCXX_STD::vector< _Tp, _Alloc >::swap ( vector< _Tp, _Alloc > & __x ) [inline]

Swaps data with another vector.

Parameters:

x A vector of the same element and allocator types.

This exchanges the elements between two vectors in constant time. (Three pointers, so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(v1,v2) will feed to this function.
