Constructs new container from a variety of data sources and optionally using user supplied allocator alloc
or comparison function object comp
.
[first, last)
. other
. If alloc
is not provided, allocator is obtained by calling std::allocator_traits<allocator_type>::select_on_container_copy_construction(other.get_allocator())
.other
using move semantics. If alloc
is not provided, allocator is obtained by move-construction from the allocator belonging to other
.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 . |
N = std::distance(first, last)
in general, linear in N
if the range is already sorted by value_comp()
.other
alloc
is given and alloc != other.get_allocator()
, then linear.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.
