WiredTiger uses a different convention for C++ access modifiers (public/protected/private) from the rest of MongoDB. For example, we have:

class component {
    public:
    component(const std::string &name, configuration *config);
    virtual ~component();
    ...

MongoDB uses the much more common C++ convention, which does not have them indented. For example, this code should be:

class component {
public:
    component(const std::string &name, configuration *config);
    virtual ~component();
    ...

We too should adopt this convention.
