In this chapter, we will introduce the observer mode. The following describes the class diagram of the observer mode example:
First, the code of the test program is provided:
Report zbo_dp_002_re.
* Include file for the class and Interface
Include zbo_dp_002_cl_if.
* Declare data
Data:
* Weather data class reference object
WD type ref to weather_data,
* Define subject interface reference object
Su type ref to subject,
* Concrete ob

./proc/sys/fs/inotify/max_user_watchesThis specifies a upper limit on the number of watches so can be created per real user ID.If you are monitoring a large directory, then other restrictions you must also consider, call read, pay attention to return is a completestruct Inotify_event {int WD; /* Watch Descriptor */uint32_t mask; /* Mask of events */uint32_t cookies; /* Unique Cookie associating relatedEvents (for rename (2)) */uint32_t Len; /* Size of
directory, the event mask indicates the inotify event to be followed by the application. Each bit corresponds to an inotify event. The Watch object is referenced by the watch descriptor, And the watches object is added by the file or directory path name. The watches directory returns the events that occur on all files in the directory.
The following function is used to add a watch:
int wd = inotify_add_watch (fd, path, mask

But sometimes, and always only execute locally tested scripts, sometimes it may be necessary to invoke the remote environment locally to perform the test, "for example: because the test environment covers the cause" at this point, you need a similar RC in SELENIUM1 to undertake this task, That is the selenium-server in selenium2. Selenium-server s
in that directory.The following function is used to add a watch:
int wd = Inotify_add_watch (fd, path, mask);
FD is the file descriptor returned by Inotify_init (), path is the pathname of the target being monitored (that is, the file name or directory name), mask is the event mask, andeach of the events represented in the header file Linux/inotify.h is defined. You can modify the event mask in the s
through three system calls and file I/operations on the returned file descriptor. The first step of using inotify is to create an inotify instance:
int fd = inotify_init ();
Each inotify instance corresponds to an independent ordered queue.
The file system change event is called an object management of watches. Each watch is a binary group (destination, event mask), and the target can be a file or directory, the event mask indicates the inotify event to

1. Create a java or javaweb project...
2. decompress the jnotify-lib-0.94 package and add the jnotify-0.94.jar to the project (java project requires manual build to path, javaweb does not need ).
3. Set up the test class jpolicytest. java as follows and use junit for testing:
Package test; import net. contentobjects. jpolicy. JNotify; import net. contentobjects. jpolicy. jpolicyexception; import net. contentobjects. jpolicy. jpolicylist
Eich still designed "inheritance." It's just that he didn't introduce the concept of class, because JavaScript is a complete object-oriented programming language once you have a "class".This seems a bit too formal, and the design of the original intention is also far, while increasing the beginner's difficulty in getting started.References to C + + and the Java language Use the new command to generate an instance:
C + + writes this:
