prototype design pattern

1. What is the prototype model The prototype pattern belongs to the creation mode of the object. The prototype pattern allows you to create a new instance by copying an existing instance.The point of this pattern is that the clie

The prototype pattern is actually similar to the factory pattern, which is used to create objects, except that they are different from the implementation of the factory pattern. The prototype pattern is to create a

address information in the registration information, the address is a separate class, copy the registration information at the same time to copy the registration information refers to the address object, so that the registration information object copy refers to a copy of the original nationality object. That is, let the address class also implement prototype mode, implement Cloneable interface.Geology Category: 1234567891011121314151617

to the public type.Prototype mode is a relatively simple pattern, and it is very easy to understand, implement an interface, rewrite a method that completes the prototype mode. In practical applications, prototype patterns rarely appear alone. Often mixed with other patterns, his prototype class

Prototype of Design Pattern The object created by the factory method is a new object, and its attributes are generally default. What I understand is that the prototype operation method creates a clone body, which can be considered as two steps: 1. creates an object. 2. copy the attributes of the created object as the c

Prototype mode of thinking: An object as a prototype, copy it, clone, and produce a new object similar to the original object.By the visible, a prototype class, only need to implement Cloneable interface, replication Clone method.In Java, there are two kinds of clones: the depth of the point, specific to see HTTP://BLOG.CSDN.NET/ZHANGJG_BLOG/ARTICLE/DETAILS/18369

The prototype pattern is actually creating another customizable object from one object without needing to know the details of any creation.. NET provides the ICloneable interface in the System namespace, which is the only method clone (), so that you can only implement this interface to complete the prototype mode. (choose "Big talk
