design patterns reusable object oriented

Lua Object-oriented implementations:A class is like a stencil that creates an object. Some object-oriented languages provide the concept of classes in which each object is an instance of a particular class. LUA does not have a cla

Method Invocation Pattern When a function is saved as an attribute of an object, we call it a method of the object, so this is bound to the object. Copy Code code as follows: var myobject={ Name: "MyObject", value:0, Increment:function (num) { This.value + = typeof (num) = = ' number '? num:0; } , Tostring:function () { Return ' [

association between people and Student student.prototype = object.create (people.prototype); var human = new People ("Joy"); Human.sayyourself ()// var studenta = new Student ("Cindy", "Junior"); Studenta.sayyourself ()// Such code seems to solve the problem of inheritance, but it is very cumbersome, the following is my recommendation for the delegate-oriented, and object-related

other method "is written separately from the method you would have called, which is low coupling." When you call a method, sping AOP does something else for this method in other classes. The first three of these four types are easy to understand and use, it is simply that this method runs with additional methods running, and the fourth note is that Spring AOP allows you to force this interface into a new interface type without changing the original interface and implementation. The new method i

.friends); //output: John Doe, Harry, Zhao Liualert (person2.friends);//output: John Doe, Harry, Zhao LiuAnalyzing the code above, when we add a friend for Person1, we find that Person2 has also been added a friend, but this is not what we want, and this is due to the shared nature of the prototype pattern, as long as any one instance modifies the property value in the Prototype Property object, All instances associated with the prototype

only one change point (every class shocould attempt to make sure that it has only one reason to this, the death of each badly designed piece of software .) What remains unchanged in the software is changes. Poor design will cause the software to crash in changes, but good software can be easily changed. Each type has only one reason for change, which will make your software relatively simple to cope with changes. In other words, reduce the change

more detailed description, after reading this article, I believe you should almost understand, online a lot of master JS writing, monomer mode is very common. A monomer is an object that is used to partition a namespace and organize a group of related properties and methods together, and if he can be instantiated, he can only be instantiated once. Monomer mode is one of the most basic but also most useful patte
