use of the enum name

If someone uses enum name as follows:

class Logger
{
 public:
           enum LEVEL
           {
               Debug,
               Warning,
               Notification,
               Error
           };
};

What would this thing mean here:

Logger(LEVEL);

LEVEL is an enum, It means that LEVEL can only be of values Debug, Warning,Notification, or Error. Logger(LEVEL); is a call to constructor Logger() of the class Logger that accepts values only from among Debug, Warning,Notification, and Error as its first parameter and probably initializes the property LEVEL to the value supplied.

This looks like the declaration of a constructor, to be used like this:

struct Logger
{
    enum LEVEL { Debug, Warning, Notification, Error };
    Logger(LEVEL);
    // ...
};

Logger wlogger(Logger::Warning);
Logger elogger(Logger::Error);
