如何从 Java watchservice 注销目录?
How do I unregister a directory from Java watchservice?
我向我的 watchService 注册了一个文件夹:
path.register(watchService, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY);
稍后,我想取消这个注册。我知道我需要以某种方式告诉 watchService 我想取消哪个 WatchKey。完成此操作的正确函数是什么?
WatchKey的注册方法returns,如documentation, which has a cancel()
方法所述。
您在 Watchable
接口 javadoc 中有提供注册 Watchable
对象(例如 Path
实例)方法的信息
public 可观看界面
This interface defines the register method to register the object with
a WatchService returning a WatchKey to represent the registration. An
object may be registered with more than one watch service.
Registration with a watch service is cancelled by invoking the key's
cancel method.
所以你只需要做:
WatchKey watchKey = path.register(watchService, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY);
...
watchKey.cancel();
