Constructs new container from a variety of data sources and optionally using user supplied allocator `alloc`

or comparison function object `comp`

.

1) Default constructor. Constructs empty container.

2) Constructs the container with the contents of the range

`[first, last)`

.
3) Copy constructor. Constructs the container with the copy of the contents of

`other`

. If `alloc`

is not provided, allocator is obtained by calling `std::allocator_traits<allocator_type>::select_on_container_copy_construction(other.get_allocator())`

.
4) Move constructor. Constructs the container with the contents of

`other`

using move semantics. If `alloc`

is not provided, allocator is obtained by move-construction from the allocator belonging to `other`

.
5) Constructs the container with the contents of the initializer list

`init`

. alloc | - | allocator to use for all memory allocations of this container |

comp | - | comparison function object to use for all comparisons of keys |

first, last | - | the range to copy the elements from |

other | - | another container to be used as source to initialize the elements of the container with |

init | - | initializer list to initialize the elements of the container with |

Type requirements | ||

-`InputIterator` must meet the requirements of `InputIterator` . |
||

-`Compare` must meet the requirements of `Compare` . |
||

-`Allocator` must meet the requirements of `Allocator` . |

1) Constant

2) N log(N) where

`N = std::distance(first, last)`

in general, linear in `N`

if the range is already sorted by `value_comp()`

.
3) Linear in size of

`other`

4) Constant. If

`alloc`

is given and `alloc != other.get_allocator()`

, then linear.
5) N log(N) where

`N = init.size())`

in general, linear in `N`

if `init`

is already sorted by `value_comp()`

.After container move construction (overload (4)), references, pointers, and iterators (other than the end iterator) to `other`

remain valid, but refer to elements that are now in `*this`

. The current standard makes this guarantee via the blanket statement in §23.2.1[container.requirements.general]/12, and a more direct guarantee is under consideration via LWG 2321.
