NAME

std::sub_match<BidirIt>::operatorstring_type,std::sub_match<BidirIt>::str - std::sub_match<BidirIt>::operatorstring_type,std::sub_match<BidirIt>::str

Synopsis

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:
