This article mainly explains "Java access C++ method is what", the explanation content in the article is simple and clear, easy to learn and understand, please follow the idea of Xiaobian slowly in-depth, together to study and learn "Java access C++ method is what"!

JavaCPP provides efficient access to native C++ in Java. JNI technology implementation, support all Java implementations including Android system, Avian and RoboVM.

JavaCPP provides a series of annotations that map Java code to C++ code and use an executable jar package to convert C++ code into dynamic link library files that can be invoked from within the JVM.

Maven:

org.bytedeco javacpp 0.11

How to use:

C++：

#include namespace LegacyLibrary { class LegacyClass { public: const std::string& get_property() { return property; } void set_property(const std::string& property) { this->property = property; } std::string property; }; }

Java：

import org.bytedeco.javacpp.*; import org.bytedeco.javacpp.annotation.*; @Platform(include="LegacyLibrary.h") @Namespace("LegacyLibrary") public class LegacyLibrary { public static class LegacyClass extends Pointer { static { Loader.load(); } public LegacyClass() { allocate(); } private native void allocate(); // to call the getter and setter functions public native @StdString String get_property(); public native void set_property(String property); // to access the member variable directly public native @StdString String property(); public native void property(String property); } public static void main(String[] args) { // Pointer objects allocated in Java get deallocated once they become unreachable, // but C++ destructors can still be called in a timely fashion with Pointer.deallocate() LegacyClass l = new LegacyClass(); l.set_property("Hello World! "); System.out.println(l.property()); } } Thank you for reading, the above is "Java access to C++ method is what" content, after learning this article, I believe that we have a deeper understanding of Java access to C++ method is what this problem, the specific use of the situation also needs to be verified by practice. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
