1、实现克隆操作,在 JAVA 继承 Cloneable,重写 clone(),在 .NET 中可以使用 Object 类的 MemberwiseClone() 方法来实现对象的浅拷贝或通过序列化的方式来实现深拷贝。 2、原型模式同样用于隔离类对象的使用者和具体类型(易变类)之间的耦合关系,它同样要求这些"易变类"拥有稳定的接口。 应用实例: 1、细胞分裂。
The 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 - resulting...
// 在Design Pattern上,以下的clone是抽象未实作的 // 实际上在Java中class都继承自Object // 所以在这边我们直接重新定义clone() // 这是为了符合Java现行的clone机制 protected Object clone() throws CloneNotSupportedException { return super.clone(); ...
When an object is required that is similar to an existing object or when the creation would be expensive compared to cloning. I hope you liked this post on a Java prototype pattern example. If you have any questions, drop a comment. Happy Learning !!
This example is rather trivial, but the real use of the pattern comes when we don’t know what we’re actually cloning. For example if we need the newly created object to be stored in a hashtable we can use it like this: // Violation of Likov's Substitution Principle ...

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: ...
