However, when we send the message out, it matches the type to ensure that our message is correctly sent to the corresponding place.This implementation is simpler than the original implementation of the JDK. Eventobserver no longer needs to exist in an inheritance system, and inheritance is always a yoke that puts us in a system: We don't have to follow

It is necessary to mention that the Trolltech company is substantively involved in the KDE project, as mentioned earlier that the porting of Netscape 5.0 was done by Trolltech programmers, while the initiator of the KDE project, the Matthias Ettrich, who also left academia in 1998 to join Trolltech, has been the head of software development for the company, so Trolltech has a very strong influenc

You can already intuitively understand how things work, and easily mediate between architecture, coding, and debugging. In general, you don't have to think about things, like when you go shopping from home to the store-you know how to go, and if there are new roads, you can weigh the different optio

pattern is used in many thread-safe classes, such as vectors and other synchronous collection classes. In this case, all variables in the state of the object are protected with an object's built-in lock. However, there is nothing special about this pattern, and neither the compiler nor the runtime enforces this pattern, and if you forget to use it when adding new methods or code paths, the yoke protocol can be easily destroyed.Not all data requires l

reins have a history of over 4000 years. This is the origin of agriculture. It is the beginning for humans to tame other animals and shows that humans stand out in all creatures. The earliest appearance of the reins can be traced back to more than 6000 years ago. According to the archaeological findings, at that time, humans had conquered the horse to work for themselves. The appearance of the reins, as documented in the text, began to widely use horses as mounts in Egypt before 4000. The earli

It not only frees people from the bottom-level details, has no object-oriented thinking yoke, but also has some very good designs, such as strong type checking, nested function definitions, and so on.
