  - isDone
```
public final boolean isDone()
```
    Returns whether or not the transfer is finished (i.e. completed successfully, failed, or was canceled). This method should never block.
    
    指定者:
    
    isDone 在接口中 Transfer
    
    返回:
    
    Returns true if this transfer is finished (i.e. completed successfully, failed, or was canceled). Returns false if otherwise.
  - waitForCompletion
```
public void waitForCompletion()
                       throws CosClientException,
                              CosServiceException,
                              InterruptedException
```
    Waits for this transfer to complete. This is a blocking call; the current thread is suspended until this transfer completes.
    
    指定者:
    
    waitForCompletion 在接口中 Transfer
    
    抛出:
    
    CosClientException - If any errors were encountered in the client while making the request or handling the response.
    
    CosServiceException - If any errors occurred in Qcloud COS while processing the request.
    
    InterruptedException - If this thread is interrupted while waiting for the transfer to complete.
  - waitForException
```
public CosClientException waitForException()
                                    throws InterruptedException
```

    指定者:
    
    waitForException 在接口中 Transfer
    
    返回:
    
    Any error that occurred while processing this transfer. Otherwise returns null if no errors occurred.
