UML Class Diagram Implementation 这里用到了围棋的例子。 棋盘上的棋子之间非常相似,除了位置不同之外就是黑白两色,如果一个棋盘上需要创建几百个对象实在是太浪费了,使用Flyweight Pattern。 // Shape.javapackagedesignpatterns.structuralpatterns.flyweight;publicinterfaceShape{voiddraw(); }// ShapeImpl.javapackaged...
Flyweight pattern tries to reuse already existing similar kind objects by storing them and creates new object when no matching object is found. This type of design pattern comes under structural pattern. Below is an example with diagram and code as further explanation. Diagram Code Explanation. We...
抽象享元类Flyweight:绘制图像的抽象方法 public abstract class Shape { public abstract void draw(); } 具体享元类ConcreteFlyweight:例子中则是一种绘制某种图像(圆形)的具体实现类,里面的颜色则是一个可以共享的内部对象。 public class Circle extends Shape{ private String color; public Circle(String color)...
结构型——享元模式 Flyweight Pattern 引子 主要用于减少创建对象的数量,以减少内存占用和提高性能。 在享元模式中通常会出现工厂模式,需要创建一个享元工厂来负责维护一个享元池(Flyweight Pool)用于存储具有相同内部状态的享元对象。 最经典的享元模式代码: ...
class libraryFlyweight pattern provides a method to improve the runtime efficiency of some object-oriented design, especially when a large amount of objects exist in the system. In this paper, the implementation of flyweight pattern in JTable which is a table control in JDK's class library is...
Finally, the third phase re-assigns representational matchings using the flyweight design pattern to construct a model with nonredundant geometric elements.
