What is a prototype pattern? In Gof's design pattern: The basics of reusable object-oriented software: Use a prototype instance to specify the type of object to create and create a new object by copying the prototypes. In this definition, the most important word is "copy",

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

prototypes is more convenient than manual instantiation. (5) classes are not easy to create. For example, each component can use other components as a combination object of subnodes. It is easier to copy existing composite objects and modify copies. This mode is used to generate a real copy of an object to serve as the basis (prototype) for other related things

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.

This article is based on Zen of design patterns and Java and patterns. 1. specify the type of the object to be created by providing a prototype object. Ii. Semi-support in Java 1. The ojbect class provides a clone method. 2. Java must implement cloneable to explicitly demonstrate that JavaBean supports replication. 3. If you use the cloneable interface directly, java.
