如何保持在Java code A C ++对象？可能？ [英] How to keep a C++ object inside Java code? Possible?

问题描述

首先，我有一个传统的C ++库，而我迁移我的应用程序到Android新用户界面。

First I've got a legacy C++ library, and I'm migrating my app to Android with new UI.

在运行时，可能有多个C ++动态创建和销毁的对象。我建立了一套JNI本地方法调用到图书馆来获取。但是，在我应该让那些C ​​++对象？我必须让他们的轨道，释放他们，如果他们是不必要的。

During runtime, there might be multiple C++ objects created and destroyed dynamically. I built a set of JNI native methods to call into library to get that. But where should I keep those C++ objects? I have to keep track of them and free them if they're unnecessary.

到目前为止，我只知道的Java不能引用到C ++对象。是否有可能使一个Java包装类，其中包括引用C ++对象？

So far I only knew Java can't reference to a C++ object. Is it possible to make a Java wrapper class which include a reference to C++ object?

感谢。

推荐答案

是的，这是可能的。您可以在一个简单的Java INT存储一个指针到C ++对象。这究竟是如何痛饮做到这一点。

Yes, it's possible. You can store a pointer to your C++ object in a simple java int. That's exactly how SWIG does that.
