Casting to pointer isn't passing by reference #576
Description
I would like to let the address from LWJGL into JavaCpp of the long type.
What we doing: public native int add(@ByRef @Cast("vk::DescriptorImageInfo*") long ptr);
Result CPP code:
JNIEXPORT jint JNICALL Java_org_helixd2s_yavulkanmod_wrapper_Alter_00024BucketOfDescriptorImageInfo_add(JNIEnv* env, jobject obj, jlong arg0) {
::cpp21::bucket<vk::DescriptorImageInfo>* ptr = (::cpp21::bucket<vk::DescriptorImageInfo>*)jlong_to_ptr(env->GetLongField(obj, JavaCPP_addressFID));
if (ptr == NULL) {
env->ThrowNew(JavaCPP_getClass(env, 9), "This pointer address is NULL.");
return 0;
}
jlong position = env->GetLongField(obj, JavaCPP_positionFID);
ptr += position;
jint rarg = 0;
jthrowable exc = NULL;
try {
int rval = ptr->add((vk::DescriptorImageInfo*)arg0);
rarg = (jint)rval;
} catch (...) {
exc = JavaCPP_handleException(env, 8);
}
if (exc != NULL) {
env->Throw(exc);
}
return rarg;
}Compiler error:
