ExampleThe Prototype pattern specifies the kind of objects to create using a prototypical instance. Prototypes of new products are often built prior to full production, but in this example, the prototype is passive and does not participate in copying itself. The mitotic division of a cell - ...

Example 1 In building stages for a game that uses a maze and different visual objects that the character encounters it is needed a quick method of generating the haze map using the same objects: wall, door, passage, room... The Prototype pattern is useful in this case because instead of ...
Java Design Pattern(Factory,Singleton,Prototype,Proxy) 一、Factory 设计模式: the most common pattern,create a new object ,eg. A a=new A();工厂模式的好处:工厂模式可以做到把创建对象单独提出来,起到解耦作用,即:如果要修改创建对象的逻辑不用在项目里的各处修改了,只需要在工厂里面修改一处就可以了,...
Aprototypeis a template of any object before the actual object is constructed. In Java, it also has the same meaning.The prototype design pattern is used in scenarios where an application needs to create a number of instances of a class that have almost the same state or differ very little...

原型模式虽然是创建型的模式,但是与工程模式没有关系,从名字即可看出,该模式的思想就是将一个对象作为原型,对其进行复制、克隆,产生一个和原对象类似的新对象。本小结会通过对象的复制,进行讲解。在Java中,复制对象是通过clone()实现的,先创建一个原型类: ...

All magic of the Prototype pattern is based on aclone()method of a java Object. So let’s to consider an example of usage and then I will try to figure out which cons and pros this pattern has. The class diagram above shows to us an basic sense of the pattern. An abstract class ...
