Class libraries: Methods and constants that contain a bunch of classes so that we call directly(1) Numerical class numericBase class numeric contains two subclasses integer (integer) and float (floating-point number)where integer (integer) can also be divided into two subclasses fixnum (Ordinary integer) and bignum (large integer)memorize integers and floating-po

I sorted out a small tool class from Lao Zhao, a small tool class for testing, and a tool class from Lao Zhao. I sorted out a test tool class from Lao Zhao without changing anything else. I just changed the class name and method name to a name that I prefer. The Code is as f

// Obtain the type information // If you call another DLL // System. reflection. Assembly ASMB = system. reflection. Assembly. loadfrom("DLL name "); // Type T = ASMB. GetType ("Class Name "); // If other DLL is not called System. type T = system. type. GetType ("Class Name "); Try { Object dobj = activator. createinstance (t ); // Obtain method information System. reflection. methodinf

Internal classes that use static adornments are called static inner classes, but we prefer to call them nested inner classes . There is one big difference between static inner and non-static inner classes, and we know that a non-static inner class implicitly holds a reference after compilation, which points to the perimeter in which it was created, but does not have a static inner class. Without this refere

In multithreading, to maintain data consistency, you must lock the data or function that accesses the data. This is common in the database, but most of the programs are single-threaded, so no lockBut in multithreading, to maintain data synchronization, the lock must be required. Fortunately, the framework has provided us with three locking mechanisms, namely, the monitor class and lock.Keyword and mutex class.The usage of the lock keyword is relativel

AngularJS uses ng-class to dynamically increase or decrease the class style. For example, angularjsng-class This article describes how AngularJS uses ng-class to dynamically increase or decrease the class style. We will share this with you for your reference. The details are

The Framework provides three locking mechanisms: the Monitor class, the Lock key word, and the Mutex class. 　　In general, lock and monitor can lock objects or functions, while mutex is generally used to lock functions and ensure that functions are synchronously called between different threads, without being affected by the thread priority. When the lock and monitor objects are used to lock an object (that

built-in class map/built-in type map About built-in classesMap is a built-in class that can return a map of obj. The first parameter of map is an executable function, and subsequent parameters are iterated objects, and map iterates over subsequent parameters and passes them to the executable function, saving the result.1 def Foo (A, B, c): 2 return a+b+C3print(list (map (foo, range (4), Range (4), Range

Because some frameworks are designed to often see Db::get (' Mall ')->where (' AAA '); Why can't you do this? Db::get (' Mall '):: Where (' aaa '); Other problems are that objects produced through a factory or a static container are generally cost-static.For example, a log class, I have seen static also seen in the non-static design. A little choice. Don't tell me what type of tool is best static, no new crap. Reply content: Because some framewor
