    享元模式介紹

    享元模式適用場景

    面向對象技術可以很好的解決一些靈活性或可擴展性問題,但在很多情況下需要在系統中增加類和對象的個數。當對象數量太多時,將導致對象創建及垃圾回收的代價過高,造成性能下降等問題。享元模式通過共享相同或者相似的細粒度對象解決了這一類問題。

    享元模式定義

    享元模式(Flyweight Pattern),又稱輕量級模式(這也是其英文名為FlyWeight的原因),通過共享技術有效地實現了大量細粒度對象的復用。

    享元模式類圖

    享元模式類圖如下

    享元模式角色劃分

    • FlyWeight 享元接口或者(抽象享元類),定義共享接口
    • ConcreteFlyWeight 具體享元類,該類實例將實現共享
    • UnSharedConcreteFlyWeight 非共享享元實現類
    • FlyWeightFactory 享元工廠類,控制實例的創建和共享

    內部狀態 vs. 外部狀態

    • 內部狀態是存儲在享元對象內部,一般在構造時確定或通過setter設置,并且不會隨環境改變而改變的狀態,因此內部狀態可以共享。
    • 外部狀態是隨環境改變而改變、不可以共享的狀態。外部狀態在需要使用時通過客戶端傳入享元對象。外部狀態必須由客戶端保存。

    package com.jasongj.flyweight;

    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;

    public class ConcreteFlyWeight implements FlyWeight {

    private static final Logger LOG = LoggerFactory.getLogger(ConcreteFlyWeight.class);

    private String name;

    public ConcreteFlyWeight(String name) {
    this.name = name;
    }

    @Override
    public void action(String externalState) {
    LOG.info("name = {}, outerState = {}", this.name, externalState);
    }

    }

    享元模式中,最關鍵的享元工廠。它將維護已創建的享元實例,并通過實例標記(一般用內部狀態)去索引對應的實例。當目標對象未創建時,享元工廠負責創建實例并將其加入標記-對象映射。當目標對象已創建時,享元工廠直接返回已有實例,實現對象的復用。

    package com.jasongj.factory;

    import java.util.concurrent.ConcurrentHashMap;

    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;

    import com.jasongj.flyweight.ConcreteFlyWeight;
    import com.jasongj.flyweight.FlyWeight;

    public class FlyWeightFactory {

    private static final Logger LOG = LoggerFactory.getLogger(FlyWeightFactory.class);

    private static ConcurrentHashMap<String, FlyWeight> allFlyWeight = new ConcurrentHashMap<String, FlyWeight>();

    public static FlyWeight getFlyWeight(String name) {
    if (allFlyWeight.get(name) == null) {
    synchronized (allFlyWeight) {
    if (allFlyWeight.get(name) == null) {
    LOG.info("Instance of name = {} does not exist, creating it");
    FlyWeight flyWeight = new ConcreteFlyWeight(name);
    LOG.info("Instance of name = {} created");
    allFlyWeight.put(name, flyWeight);
    }
    }
    }
    return allFlyWeight.get(name);
    }

    }

    從上面代碼中可以看到,享元模式中對象的復用完全依靠享元工廠。同時本例中實現了對象創建的懶加載。并且為了保證線程安全及效率,本文使用了雙重檢查(Double Check)。

    本例中,name可以認為是內部狀態,在構造時確定。externalState屬于外部狀態,由客戶端在調用時傳入。

    享元模式分析

    享元模式優點

    • 享元模式的外部狀態相對獨立,使得對象可以在不同的環境中被復用(共享對象可以適應不同的外部環境)
    • 享元模式可共享相同或相似的細粒度對象,從而減少了內存消耗,同時降低了對象創建與垃圾回收的開銷

    享元模式缺點

    • 外部狀態由客戶端保存,共享對象讀取外部狀態的開銷可能比較大
    • 享元模式要求將內部狀態與外部狀態分離,這使得程序的邏輯復雜化,同時也增加了狀態維護成本

    享元模式已(未)遵循的OOP原則

    已遵循的OOP原則
