Back to Object Pool description """ Offer a significant performance boost; it is most effective in situations where the cost of initializing a class instance is high, the rate of instantiation of a class is high, and the number of instantiations in use at any one time is low. """ ...
In many applications of the Object Pool pattern, there are reasons for limiting the total number ofReusableobjects that may exist. In such cases, theReusablePoolobject that createsReusableobjects is responsible for not creating more than a specified maximum number ofReusableobjects. IfReusablePoolobje...
本文大部分内容翻译至《Pro Design Pattern In Swift》By Adam Freeman,一些地方做了些许修改,并将代码升级到了Swift2.0,翻译不当之处望多包涵。 对象池模式(The Object Pool Pattern) 对象池模式是单例模式的一个变种,它提供了获取一系列相同对象实例的入口。当你需要对象来代表一组可替代资源的时候就变的很有用...
The clients are not aware that they are sharing the Reusable object. From the client poinf of view they are the owners of a new object which comes from the Resource pool in the same way that it comes from a factory or another creational design pattern. The only difference is that the C...

The Factory Method pattern can be used to encapsulate the creation logic for objects. However, it does not manage them after their creation, the object pool pattern keeps track of the objects it creates. Object Pools are usually implemented as Singletons. ...
如果Client 调用 ObjectPool 的 AcquireReusable() 方法来获取 Reusable 对象,当在 ObjectPool 中存在可用的 Reusable 对象时,其将一个 Reusable 从池中移除,然后返回该对象。如果池为空,则 ObjectPool 会创建一个新的 Reusable 对象。 1namespaceObjectPoolPattern.Implementation12{3publicabstractclassObjectPool<T>...
Advantage of Object Pool design pattern It boosts the performance of the application significantly. It is most effective in a situation where the rate of initializing a class instance is high. It manages the connections and provides a way to reuse and share them. ...
because the pool has no control over when resources are actually reclaimed. Other options are FIFO and LIFO; FIFO will have more of a random-access pattern, but LIFO makes it significantly easier to implement a Least-Recently-Used freeing strategy (which you said was out of scope, but it'...
对象池模式(Object Pool Pattern) 本文节选自《设计模式就该这样学》 1 对象池模式的定义对象池模式(Object Pool Pattern),是创建型设计模式的一种,将对象预先创建并初始化后放入对象池中,对象提供者就能利用已有的对象来处理请求...对象池是一个特殊的工厂对象,对象池模式就是单例模式加享元模式。 2 对象池模式...
