- Method Detail
  - getLock
```
L getLock(Object key)
```
    Returns a lock for the specified key. Implementations will normally do the following: when the first thread calls this method with a key, a new lock is created and returned. When a second, third and so on concurrent thread tries to get a lock for the same key, the first lock is returned, thus allowing synchronization based on the key.
    
    Parameters:
    
    key - the key associated with the lock
    
    Returns:
    
    the lock
