  - locations
```
List<ServerLocation> locations()
```
    Represents a list of one or more ServerLocation's where BlockState changes can occur.
    Canceling this event will prevent block logic from running and also stop BlockSnapshot's from being generated.
    
    Note: This event is not intended to always be fired before changing a BlockState but rather it is primarily used to prevent one or more BlockState's from being changed.
    
    Returns:
    
    The immutable list of one or more locations that can change
