  - clear
```

```
    Flushes the internal state of the list, setting the capacity of the empty list to capacity.
    
    Parameters:
    
    capacity - an int value
  - reset
```
public void reset()
```
    Sets the size of the list to 0, but does not change its capacity. This method can be used as an alternative to the clear method if you want to recyle a list without allocating new backing arrays.
    
    See Also:
    
    clear()
  - resetQuick
```
public void resetQuick()
```
    Sets the size of the list to 0, but does not change its capacity. This method can be used as an alternative to the clear method if you want to recyle a list without allocating new backing arrays. This method differs from reset in that it does not clear the old values in the backing array. Thus, it is possible for getQuick to return stale data if this method is used and the caller is careless about bounds checking.
