std::regex_iterator::operator==

bool operator==(const regex_iterator& rhs) const;
Compare regex_iterator
Returns true if rhs compares equal to the regex_iterator object.

Two regex_iterator compare equal if any of these is true:
  • They are both end-of-sequence iterators
  • One was constructed as or assigned to a copy of the other and are now pointing to the same match.
  • They were both constructed with equivalent arguments for first, last and flags, both use the same regex object, and both now point to the same match (their internal match_results objects compare equal).

Parameters

rhs
Another regex_iterator object of the same type.

Return value

true if both regex_iterator compare equal. false otherwise.

// regex_iterator example
#include <iostream>
#include <string>
#include <regex>

int main ()
{
  std::string s ("this subject has a submarine as a subsequence");
  std::regex e ("\\b(sub)([^ ]*)");   // matches words beginning by "sub"

  std::regex_iterator<std::string::iterator> rit ( s.begin(), s.end(), e );
  std::regex_iterator<std::string::iterator> rend;

  while (!(rit==rend)) {
    std::cout << rit->str() << std::endl;
    ++rit;
  }

  return 0;
}


Output:
subject
submarine
subsequence
