C++ lambda capture this vs capture by reference

Question

If I need to generate a lambda that calls a member function, should I capture by reference or capture \'this\'? My understanding is that \'&\' captures only the variable

Answer 1

Capturing this and capturing by reference are two orthogonal concepts. You can use one, both, or none. It doesn't make sense to capture this by reference but you can capture other variables by reference while capturing this by value.
