24.6.11.3 Constructors [flat.set.cons]

🔗
explicit flat_set(container_type cont, const key_compare& comp = key_compare());
1
#
Effects: Initializes c with std​::​move(cont) and compare with comp, sorts the range [begin(), end()) with respect to compare, and finally erases all but the first element from each group of consecutive equivalent elements.
2
#
Complexity: Linear in N if cont is sorted with respect to compare and otherwise , where N is the value of cont.size() before this call.
🔗
template<class Allocator> flat_set(const container_type& cont, const Allocator& a); template<class Allocator> flat_set(const container_type& cont, const key_compare& comp, const Allocator& a);
3
#
Constraints: uses_allocator_v<container_type, Allocator> is true.
4
#
Effects: Equivalent to flat_set(cont) and flat_set(cont, comp), respectively, except that c is constructed with uses-allocator construction ([allocator.uses.construction]).
5
#
Complexity: Same as flat_set(cont) and flat_set(cont, comp), respectively.
🔗
template<class Allocator> flat_set(sorted_unique_t s, const container_type& cont, const Allocator& a); template<class Allocator> flat_set(sorted_unique_t s, const container_type& cont, const key_compare& comp, const Allocator& a);
6
#
Constraints: uses_allocator_v<container_type, Allocator> is true.
7
#
Effects: Equivalent to flat_set(s, cont) and flat_set(s, cont, comp), respectively, except that c is constructed with uses-allocator construction ([allocator.uses.construction]).
8
#
Complexity: Linear.

Constraints: uses_allocator_v<container_type, Allocator> is true.

#
Effects: Equivalent to the corresponding non-allocator constructors except that c is constructed with uses-allocator construction ([allocator.uses.construction]).
