Finds members of type const string&
.
const string reference members are generally considered unsafe as they can be created from a temporary quite easily.
In the constructor call a string temporary is created from const char *
and destroyed immediately after the call. This leaves around a dangling reference.
This check emit warnings for both std::string
and ::string
const reference members.
Corresponding cpplint.py check name: 'runtime/member_string_reference'.

Override this to register AST matchers with Finder
.
This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.
You can register as many matchers as necessary with Finder
. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.
If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.
