Clang-AST traversal - How to get class member variables

I want to go through the AST of a simple class having one member variable and one method. I realized that the class is represented as CXXRecordDecl.

What is the api inside CXXREcordDecl to get the list of member variables that are represented as FieldDecl?

Fields can be retrieved using RecordDecl::fields

(there are also methods that get the start and end iterators of that range) for example. for aCXXRecordDecl 

CXXRecordDecl* cl = ...;
for (const auto& field : cl->fields) {
    const auto& name = field->getName();
    const auto field_cl = field->getType()->getAsCXXRecordDecl(); 
}


Likewise, you can access methods with methods()

.
