. In the override of the method: The number of parameters of the method of the subclass, the method name, and the number of arguments to the parent method, as well as the method name Subclass methods cannot narrow the access rights of the parent method (can be greater than can be equal) Note: If the method name of the parent class is private, the subclass is not overridden. Override of property For property overrides also, public and protected can be overridden, private properties c

child class must be the same. In method rewriting: Number of parameters of the subclass method, method name, which must be the same as the number of parameters of the parent method. Subclass methods cannot reduce the access permission of the parent method (which can be greater than or equal) Note: If the method name of the parent class is private, the subclass will not be overwritten. Overwrite attributes Public and protected attributes can be overwritten, while private attributes cannot be

Sync-settings IntroductionSync-settings is a backup plugin that backs up Atom's global settings, plug-ins, key bindings (keymaps), interface styles, code Snippets (snippets), and init script.Sync-settings ConfigurationConfiguration Items Access Token and Gist Id need to go to GitHub to request a buildRequest to generate token and gist IDGist is a feature of GitHub that allows you to record code snippets and save the code you use frequently in your work or the good code you browse on GitHub in Gi

directly from the main memory, the performance of the synchronization mode will be more excellent.If your real-world application is the opposite, there is a lot of swapping in and out, and your system has a lot of cores, because of this, you do not want the client to have to block a short period of time before accessing the swap file, if it is true, I think the Async method may be more suitable for your system.As for the final choice of configuration, the best answer will come from constant exp

); This. Closepath ();return This; } This method is both precise and less code, and there is no strange and difficult place to understand. Just keep in mind that the width of the ellipse is proportional to the coordinates of the control point of the Bezier curve that draws the ellipse as follows:Bezier Control Point x= (ellipse width/0.75)/2 This is already reflected in the code.You can experiment with the above 4 methods to draw an ellipse.If you find a simpler way, please share it with us.[T

11. Open, close, and delete file and directory generation We have analyzed the read, and the write is similar to the read. There are other operations in the file system. For example, open a file or directory (open an existing directory or create a new one) and close it. Move or delete files or directories. In fact, file_object is not just a file object. In Windows file systems, both directories and files are abstracted using fileobject. Here is

Python tutorial 11 -- Python decorator A function is also an object, and a function object can be assigned to a variable. Therefore, a function can also be called through a variable. The function object has a (Double underline + name + double underline) attribute. You can get the function name: Now, let's assume that we want to enhance the functions of the now () function, for example, to automatically pri

When you write code, you often see the following:Everyone knows that this is due to the introduction of unused packages, so eclipse gives hints to tell you that these are useless references that affect aesthetics, increase the amount of space the code occupies, and add a burden to the compilation of the code. So for these useless code, we should remove it. Let's take a look at three ways to get rid of useless references.The first type: Remove theWhen an unused reference exists in a class, the sh
