The JNI Bridge Generator allows you to generate C++ proxies for Java classes, using Java Annotation Processors and Velocity templates.

No. The JNI Bridge Generator is designed to make the development of Java/C++ applications as easy as possible:

• Generate the bindings while writing your Java code
• One annotation to rule them all: no complex configuration, just use a single annotation
• Focus on your problems and use Java classes transparantly in C++.

The JNIBridgeGenerator generates C++ proxies for

• public Java classes,
• public methods.

The generated classes allow you to use the Java classes in your C++ applications as if they were normal C++ classes. You can create them, delete them, even inherit them.

These features are in progress:

• Generics, mapping to C++ templates
• Interfaces, supporting C++ implementation of a Java interface.

Add the @JNIProxy annotation on

• Classes
• Constructors
• Methods

to generate C++ proxies at compile time.

package com.tecnyse.sample.integration;

import com.tecnyse.integration.JNIProxy;

@JNIProxy
public class MyClass {

  @JNIProxy
  public int foo() {
    return 1;
  }
  
  @JNIProxy
  public static String bar(int arg1, String arg2) {
    return arg2 + arg1;
  }
}

The above will generate 2 files in com/tecnyse/samples/integration (the package):

• myclass.h: declares the JNI proxy for MyClass as a C++ class in the com::tecnyse::samples::integration namespace.
• myclass.cpp: defines the JNI bindings for MyClass.

• JNIBridgeGenerator: the IntelliJ module for the generator
• test: an IntelliJ module with samples.

• Put the JNIBridgeGenerator jar on your classpath
• Add the com.tecnyse.integration.processor.JNIProxyProcessor processor in your services manifest.
• Annotate.
• Compile!
