operator string_type() const; |
(1) | |
string_type str() const; |
(2) | |
Converts to an object of the underlying std::basic_string type.
The first version is an implicit conversion, the second one is explicit.
Parameters
(none)
Return value
Returns the matched character sequence as an object of the underlying std::basic_string type. If the matched
member is false then the empty string is returned.
Complexity
Linear in the length of the underlying character sequence.
Example
Run this code
#include <iostream> #include <regex> #include <string> int main() { std::ssub_match sm; std::string s = sm; // implicit conversion std::cout << s.length() << '\n'; }
Output:
0
