示例1: operator
// Processing operator - in real life processes data for the range defined by 'r'
//
// This just calls TestThread.callback(r.begin(), r.end())
// Designed to be called on any thread
//
void operator() (const blocked_range<int>& r ) const {
// printf("operator() %d->%d\n", r.begin(), r.end());
// Attach the current thread to the JVM, allowing access to the JVM environment through 'thrdEnv'
JNIEnv *thrdEnv;
jvm->AttachCurrentThread ((void **) &thrdEnv, NULL);
// Get the TestThread instance as a jclass
jclass cls = thrdEnv->GetObjectClass(testThread);
if(cls==0) {
fprintf(stderr, "GetObjectClass returned null\n");
return;
}
// Get the method id for 'void TestThread.callback(int, int)'
jmethodID mid = thrdEnv->GetMethodID(cls, "callback", "(II)V");
if(mid==0) {
fprintf(stderr, "GetMethodID returned null\n");
return;
}
// Now call the actual method
jint s = r.begin();
jint e = r.end();
thrdEnv->CallVoidMethod(testThread, mid, s, e );
// And detach our thread
jvm->DetachCurrentThread();
