31.10.1 match_­results constructors [re.results.const]

1
#

In all match_­results constructors, a copy of the Allocator argument shall be used for any memory allocation performed by the constructor or member functions during the lifetime of the object.

match_results(const Allocator& a = Allocator());

2
#

Effects: Constructs an object of class match_­results.

3
#

Postconditions: ready() returns false. size() returns 0.

match_results(const match_results& m);

4
#

Effects: Constructs an object of class match_­results, as a copy of m.

match_results(match_results&& m) noexcept;

5
#

Effects:  Move constructs an object of class match_­results from m satisfying the same postconditions as Table 134. Additionally, the stored Allocator value is move constructed from m.get_­allocator().

6
#

Throws: Nothing.

match_results& operator=(const match_results& m);

7
#

Effects: Assigns m to *this. The postconditions of this function are indicated in Table 134.

match_results& operator=(match_results&& m);

8
#

Effects:  Move-assigns m to *this. The postconditions of this function are indicated in Table 134.
