◆ registerMatchers()

overridevirtual |
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.
This will only be executed if the function isLanguageVersionSupported returns true.
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.

◆ storeOptions()
|
overridevirtual |
Should store all options supported by this check with their current values or default values for options that haven't been overridden.
The check should use Options.store() to store each option it supports whether it has the default value or it has been overridden.
