Cast unsigned char* array into a jObject

I don't have much experience in C++. I'd like to know is it possible to convert System::Collections::Generic::List<cli::array<unsigned char>^>^ into a jObject. My requirement is to pass a jObject to Java from JNI native code. If this impossible, is there any workaround?

Solution

  • It isn't possible to cast, as per your title, but you can convert it, by wrapping it in Java byte array, via NewByteArray(), and populating it with SetByteArrayRegion().
