```
  - implies
```
public boolean implies(Permission.Action action)
```
    check if given action is granted
    
    Parameters:
    
    action - action to be checked
    
    Returns:
    
    true if granted, false otherwise

```
public void setActions(Permission.Action[] assigned)
```
  - equalsExceptActions
```
