如何在Delphi中实现线程安全的列表包装器? [英] How can I implement a thread-safe list wrapper in Delphi?

问题描述

我有一个列表包装器，其中包含两个Tstringlists和一个TClassList

I have a list wrapper that maintains two Tstringlists and a TClassList

我需要这样做是线程安全的，例如:

I need this to be thread safe, such that:

• 不允许同时写入(应输入某种等待状态)
• 不允许在写作时进行阅读(反之亦然)(应输入某种等待状态)
• 允许同时读取

关于如何执行此操作的任何想法?我的直觉告诉我，它不仅需要一个关键部分，还可能需要一个信号量或使用计数器"，或者与CS结合使用的其中一个.

Any ideas on how I can do this? My instinct tells me it needs more than just a critical section, perhaps a semaphore or "usage counter", perhaps one of these in conjunction with a CS.

我不确定从哪里开始-从英语的整体方法到伪代码，到delphi实施或外部链接的任何事物都将受到赞赏.

I'm just not quite sure where to start - anything from an overall approach in english to psuedo-code, to delphi implementation or external link would be much appreciated.

推荐答案

您应该看看sysutils.pas中声明的TMultiReadExclusiveWriteSynchronizer类.

You should have a look at the TMultiReadExclusiveWriteSynchronizer class declared in sysutils.pas...
