Shared Library |
The shared library is just a trivial implementation of the native method 'WorldOfC'. The function simply returns zero. Within the function a C++ exception is thrown and caught. The library consists of a header file Test.h and implementation file called Test.cpp
This is the header file (as generated by the javah tool):
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class Test */
#ifndef _Included_Test
#define _Included_Test
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class: Test
* Method: WorldOfC
* Signature: ()I
*/
JNIEXPORT jint JNICALL Java_Test_WorldOfC
(JNIEnv *, jobject);
#ifdef __cplusplus
}
#endif
#endif
|
The Test.cpp file contains the actual implementation of the function:
#include "Test.h"
// Dilbert is just a dummy class that we
// will throw and catch.
class Dilbert
{
public:
Dilbert() {}
~Dilbert() {}
Dilbert(const Dilbert& Orig) {}
private:
Dilbert& operator=(const Dilbert& Orig);
};
JNIEXPORT jint JNICALL Java_Test_WorldOfC
(
JNIEnv* env,
jobject object
)
{
try
{
throw Dilbert();
}
catch (const Dilbert& D)
{
// We don't actually do anything with
// the exception, we just need to confirm
// the code will not cause a segmentation fault.
}
return 0;
}
