In a service view, it corresponds to a one-way operation (with only an input or output message).

从服务的角度来看，它类似于一个单向操作(仅仅使用输入或者输出消息)。

If the operation being invoked is one way, there's no fault or out terminals because these can only exist for two-way operations (see Figure 6).

如果被调用的操作是单向的，则不存在fault或out末端，因为这两种末端只能存在于双向操作中(请参见图6)。

This is an one-way operation only, it cannot be undone. Back up the server farm before continuing.

此操作为单向操作，无法撤消。请在继续操作前备份服务器场。
