Runtime.getruntime (). Addshutdownhook (Shutdownhook);The implication of this method is that the method means adding a closed hook to the JVM, and when the JVM shuts down, it executes all the hooks that have been set in the system via the method Addshutdownhook, and the JVM shuts down when the system finishes executing the hooks. So these hooks can be used for memory cleanup, object destruction and so on when the JVM shuts down.Use1 The application ex

The CI framework allows you to add or change the core functions of the system (such as rewriting the cache, output, etc.) without altering the core code of the system.For example, under the condition of the system opening hook (config.php $config[‘enable_hooks‘] = TRUE; ). By adding a specific hook, you can have the system trigger a specific script at a specific moment:$
Hook Overview
Hook is a key point of Windows message processing mechanism ). Applications can intercept and process window messages or other specific events through the hook mechanism. Similar to the DOS interrupt interception processing mechanism, an application can set multiple hook functions on the

The user closes the shutdown program and needs to do some cleanup work, but the problem is that some users will not close the application in the recommended way, and will be able to cause the aftermath to fail. The Start method, like the Tomcat call server, starts the container and then calls the start step by step. When the shutdown command is issued, the shutdown feature is turned on, but the shutdown may have some unintended impact, resulting in the application not going to the shutdown metho
A little thought about general hook:
In the system kernel level, much of MS Information is not disclosed, including the number of parameters of the function, the type of each parameter, and so on. In the system kernel, a large number of registers are accessed, while the values of many registers are provided by the upper caller. If the value changes the system will become unstable. There are likely to be unimaginable consequences. In addition, sometim

Original question:In the game of DotA, Pudge's Meat hook is actually the most horrible thing for most of the heroes. The hook is made to several consecutive metallic sticks which is of the same length.Now Pudge wants to do some operations on the hook.
Let us number the consecutive metallic sticks of the hooks from 1 to N. For each operation, Pudge can change the

It was previously only known at development time to rely on database transactions to guarantee data integrity when the program was closed.But sometimes a business-required atomic operation does not necessarily include only databases, such as external interfaces or message queues. At this point the database transaction is helpless.At this point we can rely on Java to provide a tool method: Java.lang.Runtime.addShutdownHook (Thread Hook)The Addshutdownh
