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().
