Can someone tells me what is the `::CLOSE` in the following code :

```
Fight c;
c.type = Fight::CLOSE; //CLOSE can also become ::RANGE

```

I have to create the Fight class, but I have no idea of what is the `::CLOSE` part. 
I just know that `c.type` is a bool or an int.

Edit : An enum, not an int or a bool
