或者轮询操作的当前状态，还可取消操作。
Or it can poll the current state of the operation, and also cancel the operation.
而SNMP、CLI属于主动采集，必须让采集服务器使用轮询操作来及时取得网管数据。
However, SNMP and CLI, belonging to active acquisition, must be polled regularly by polling server.
使用incPanelValue作为探测机制所带来的好处是我们能够以可视化的方式看见OpenNMS的检测和轮询操作。
The added advantage of using the operation incPanelValue as the probing mechanism is the fact that we will be able to see the detect or poll action of OpenNMS visually.
这是因为大多数套接字操作都是异步地进行的，其中套接字进行轮询以检查数据是否出现，而不是使得应用程序处于阻塞(等待)状态以等待响应。
This is because most socket operations are made asynchronously in that the socket is polled to see if data is present rather than having the application block (wait) for the response.
同时还包含了对文件系统事件的标准的跨平台支持，比如观察目录变化(有效使用OS级别操作而非轮询)等等事件操作。
This also includes standard, cross-platform support for filesystem events, such as watching a directory for changes (using efficient OS-level operations, rather than polling).
WS - Polling具有真正的“轮询”操作。
通过使用异步api，应用程序将对外部事件进行轮询并在事件发生后执行相应的操作。
With asynchronous APIs, the application polls for external events and executes relevant actions when an event arrives.
或者，根据具体的应用程序，可能在发生特定的应用程序操作或事件后进行轮询。
Or, depending on your application, polling might occur following some particular client application action or event.
虽然WS - RM规范的确定义了可供目标端点用作创建新连接的根据的机制，但务必要理解此操作不是轮询消息。
While the WS-RM specification does define a mechanism by which the destination endpoint can establish new connections, it's important to understand that this action is not polling for a message.
轮询器守护程序pollerd将定期轮询已检测到的服务以确保它们是可操作的。
The poller daemon, pollerd, will regularly poll detected services to ensure they are operational.
实验结果证明该方法减少了通信双方握手过程中的轮询监测操作，提高了数控系统模块间的通信性能。
Experimental results show that the method can avoid polling and monitoring new data and improve the performance of inter...
