namespace ReferencePool

}ReferenceCollection 引用集合
一个类型对应一个引用集合每次请求从引用集合的队列中获取
namespace ReferencePool
{public class ReferenceCollection{private readonly QueueIReference m_References new QueueIReference();private Type m_ReferenceType;private int m_CurrUsingRefCount;//当前引用的数量private int m_AcquireRefCount;//请求引用的总数量private int m_ReleaseRefCount;//释放引用的总数量private int m_AddRefCount;//添加引用的总数量private int m_RemoveRefCount;//移除引用的总数量public int CurrUsingRefCount m_CurrUsingRefCount;public int AcquireRefCount m_AcquireRefCount;public int ReleaseRefCount m_ReleaseRefCount;public int AddRefCount m_AddRefCount;public int RemoveRefCount m_RemoveRefCount;public ReferenceCollection(Type refType){m_ReferenceType refType;m_CurrUsingRefCount 0;m_AcquireRefCount 0;m_ReleaseRefCount 0;m_AddRefCount 0;m_RemoveRefCount 0;}public T AcquireT() where T : class, IReference, new(){if (typeof(T) ! m_ReferenceType){throw new Exception(类型不相同无法请求!!!);}m_CurrUsingRefCount;m_AcquireRefCount;lock (m_References){if (m_References.Count 0){return (T)m_References.Dequeue();}}m_AddRefCount;return new T();}public void Release(IReference reference){reference.Clear();lock (m_References){if (m_References.Contains(reference)){throw new Exception(引用已经被释放请勿重新释放!!!);}m_References.Enqueue(reference);}m_CurrUsingRefCount--;m_ReleaseRefCount;}public void AddT(int count) where T : class, IReference, new(){if (typeof(T) ! m_ReferenceType){throw new Exception(类型不相同无法添加!!!);}lock (m_References){m_AddRefCount count;while (count-- 0){m_References.Enqueue(new T());}}}public void Remove(int count){lock (m_References){if(count m_References.Count){count m_References.Count;}m_RemoveRefCount count;while (count-- 0){m_References.Dequeue();}}}public void RemoveAll(){lock (m_References){m_RemoveRefCount m_References.Count;m_References.Clear();}}}
}ReferencePool 真正的引用池
对引用集合进行统一管理
public static class ReferencePool{private static readonly DictionaryType,ReferenceCollection m_ReferenceCollections new DictionaryType,ReferenceCollection();public static int Count m_ReferenceCollections.Count;//获取引用池的数量public static void ClearAll(){lock (m_ReferenceCollections){foreach (var reference in m_ReferenceCollections.Values){reference.RemoveAll();}m_ReferenceCollections.Clear();}}public static T AcquireT() where T : class, IReference, new(){return GetReferenceCollection(typeof(T)).AcquireT();}public static void Release(IReference reference){GetReferenceCollection(reference.GetType()).Release(reference);}public static void AddT(int count) where T : class, IReference, new(){GetReferenceCollection(typeof(T)).AddT(count);}public static void RemoveT(int count) where T : class, IReference, new(){GetReferenceCollection(typeof(T)).Remove(count);}public static void RemoveAllT() where T : class, IReference, new(){GetReferenceCollection(typeof(T)).RemoveAll();}private static ReferenceCollection GetReferenceCollection(Type type){if (type null){throw new Exception(Type 类型 为空!!!);}ReferenceCollection referenceCollection null;lock (m_ReferenceCollections){if(!m_ReferenceCollections.TryGetValue(type,out referenceCollection)){referenceCollection new ReferenceCollection(type);m_ReferenceCollections.Add(type, referenceCollection);}}return referenceCollection;}public static int GetCurrUsingRefCountT() where T : class, IReference, new(){return GetReferenceCollection(typeof(T)).CurrUsingRefCount;}public static int GetAcquireRefCountT() where T : class, IReference, new(){return GetReferenceCollection(typeof(T)).AcquireRefCount;}public static int GetReleaseRefCountT() where T : class, IReference, new(){return GetReferenceCollection(typeof(T)).ReleaseRefCount;}public static int GetAddRefCountT() where T : class, IReference, new(){return GetReferenceCollection(typeof(T)).AddRefCount;}public static int GetRemoveRefCountT() where T : class, IReference, new(){return GetReferenceCollection(typeof(T)).RemoveRefCount;}}3.测试
namespace ReferencePool
{public class Program{static void Main(string[] args){TeacherData teacherData1 ReferencePool.AcquireTeacherData();teacherData1.Name zzs;teacherData1.Age 20;ReferencePool.Release(teacherData1);TeacherData teacherData2 ReferencePool.AcquireTeacherData();teacherData1.Name xxx;teacherData1.Age 18;Console.WriteLine(ReferencePool.GetCurrUsingRefCountTeacherData());Console.WriteLine(ReferencePool.GetAcquireRefCountTeacherData());Console.WriteLine(ReferencePool.GetReleaseRefCountTeacherData());Console.WriteLine(ReferencePool.GetAddRefCountTeacherData());Console.WriteLine(ReferencePool.GetRemoveRefCountTeacherData());Console.ReadKey();}}public class TeacherData : IReference{public string Name;public int Age;public void Clear(){Name string.Empty;Age 0;}}
}4.总结
重复使用的对象只创建有限次避免来回实例化对象的开销
