Java Design Pattern -------- factory method pattern of creation Pattern This article is my learning notes, welcome to reprint, but please note the Source: http://blog.csdn.net/jesson20121020 One problem with the simple factory model in the previous section is that the creation of the class depends on the factory class.

and specific sub-classes. One designer is responsible for providing the outline and skeleton of an algorithm, while other designers are responsible for providing the logical steps of this algorithm. The method representing these specific logical steps is called the basic method. The method that aggregates these basic methods is called the template method ), the name of this design pattern is from here.Ii.

Java Design Pattern -------- abstract factory pattern of creation Pattern This article is my learning notes, welcome to reprint, but please note the Source: http://blog.csdn.net/jesson20121020 The factory method mode and the abstract factory mode are difficult to distinguish clearly: Factory method Mode features:

. iterator (); // rewrite while (iterator. hasnext () {itemcomponent t = (itemcomponent) iterator. next (); T. method1 () ;}} public class set2 extends itemcomponent {arraylist items ;... public iterator () {return items. iterator ();} public void Method1 () {system. out. println ("not leaf"); iterator = itemcomponent. iterator (); // rewrite while (iterator. hasnext () {itemcomponent t = (itemcomponent) iterator. next (); T. method1 ();}}} The above method is a recursive method to achieve full

Analysis on the model of data object mapping in PHP design mode and its design pattern PHP in the design pattern has a lot of different patterns, here we introduce a less common data mapping mode, I hope the article can help you. The data mapping

Responsibility Chain Pattern of JAVA design Pattern [Chain of Responsibility Pattern], javapattern I. Overview To avoid coupling between request senders and receivers, multiple objects may receive requests, connect these objects into a chain, and pass requests along the chain, until an object processes it. The responsi

Php design pattern Singleton pattern (single element pattern)Singleton mode: As the object creation mode, the singleton mode ensures that a class has only one instance, and the instance is self-instantiated and global to the entire system. It does not create instance copies, but returns a reference to the instance s

property of the person, and the constructor becomes an empty function . Even so, you can still create new objects by calling the constructor, and the new objects will have the same properties and methods. However, unlike the constructor pattern, these properties and methods of the new object are shared by all instances. In other words,person1 and person2 Access both the same set of properties and the same sayname () function. to understand the worki
