    the lock associated with the given hashCode
  - getLockWithOffset
```
public ReadWriteLock getLockWithOffset(int offset)
```
    Retrieves the given lock at a provided offset. Note this is not hashCode based. This method requires care and the knowledge of how many locks there are. This is useful when iterating over all locks
    
    Parameters:
    
    offset - the offset of the lock to find
    
    Returns:
    
    the lock at the given offset
