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
. Parameters
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 . |
Complexity
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()
