prototype design pattern

Prototype mode definition:Use a prototype instance to specify the object type and copy the prototype to create a new object. The Prototype mode allows an object to create another custom object without any details. The working principle is: pass a Prototype object to the obj

Turn from: http://blog.csdn.net/feixiaoxing/article/details/7075316 The prototype pattern is essentially a copy of the current data. Like a juggler, a dove becomes two pigeons, two pigeons become three pigeons, and it goes on and on. In the process of change, we do not need to consider the specific data types. Why, then? Because different data has its own type of replication, and each copy function is a vir

Main application scenarios of the prototype design model:1. class initialization consumes a lot of resources2. Using new to generate an object requires tedious data preparation or access permissions,The following uses sending an advertisement email as an example to describe how to use the prototype design mode.When an

The original reference books: "Design Patterns explained Simply" A, definition Find the type of object you want to create based on the saved prototype, and then create a new object from the copy (clone) based type. second, the structure Iii. main points In prototype mode, the client does not know the actual type of object to clone, just know the base class type.

All proofs: a completely independent new object is cloned through deep cloning. In Java, what are the 23 design patterns that must be understood? 1. Simple Factory Pattern)2. Builder

Combining the constructor pattern with the prototype pattern Constructor patterns are used to define instance properties, which are used to define methods and shared properties. The most common way to create custom types is by combining the constructor pattern with the
