prototype design pattern

= new A (); now you want to generate an instance B like car1, according to the prototype mode, it should be like this: A B =. clone (); instead of creating a new a object. Through the above sentence, we can get an instance that is the same as a. Specifically, it should be that their data members are the same. The prototype mode returns an object A without using the new operation. 2. What are the benefits o

This series mainly records what the design pattern intends to be, what issues it wants to solve, and when it can be used; how it solves it, master its structure diagram, remember its key code; be able to think of at least two of its application instances, one in life and one in software; What are the advantages and disadvantages of this model, and what use scenarios are there, what should I pay attention to

, some common sense friends know that the iombies are chicken cakes with cream. They are all cloned one by one with abrasive tools, so they look like the same in general. Mayonnaise has many flavors including strawberry with cream, fresh orange, and so on. So are there many egg factories that want to produce all kinds of egg tools. The answer is no! It is impractical to change the production pipeline for every kind of egg yolk pie in the factory. In fact, it is very easy to add the containers in

the builder object it wants. Director obtains the customer's request to create the product, finally obtains the product. Advantages1. The process of constructing objects can be finely controlled to produce different product objects.2. Easy to expand, there are new products, just add new concretebuilder can be achieved. Related modeThe abstract factory pattern is similar to a generator because it can also create complex objects. The main difference

Use a prototype instance to specify the type of the object to be created and copy the original object to create a new object. Public class prototypeclass implements cloneable {@ override protected object clone () {// todo auto-generated method stub prototypeclass = NULL; try {prototypeclass = (prototypeclass) super. clone ();} catch (clonenotsupportedexception e) {// todo auto-generated Catch Block E. printstacktrace ();} return prototypeclass ;}}

Design Pattern _ prototype PatternPrototype Pattternspecify the kinds of objects to create using a prototypical instance, and create new objects by coping this prototype. (use a prototype instance to specify the type of the object to be created and copy the

Prototype: Use a prototype instance to specify the object type and copy the prototype to create a new object. Prototype, Prototype class, declares an interface for cloning itself ConcretePrototype1 and ConcretePrototype2 are specific

In prototype mode, a prototype instance is used to specify the type of the object to be created, and a new object is created by copying the prototype. The Prototype mode is a creation design mode. The Prototype mode allows an obje

The prototype mode is an object creation mode.Use a prototype instance to specify the type of the object to be created and copy the prototype to create a new object.The prototype mode allows an object to create another custom object without any details.The basic working principle of the

Label: style blog HTTP color Io OS SP Div 2014 1. My description In my understanding, what is the prototype mode is to clone n objects. The cloned object should be exactly the same. Of course, you can modify the content of the cloned object. For C ++, the copy constructor is used. This mode is relatively simple, so it is no longer arrogant. Ii. UML diagram 　　 3.
