Hi @netstu
Firstly, that Java_com_daa_xx() function would need to correspond with a native method on class a.
So, in your Java...
package com.netsu;
class a {
public native void doStuff(b bobj);
}So then in your C++ code, you can make doStuff() call that assignment by using set().
extern "C" void Java_com_netsu_a_doStuff(jni::JNIEnv* env, jni::jobject obj, jni::jobject bobj)
{
jni::init(env); // Not necessary if you've done this elsewhere already...
jni::Object aobj(obj); // The aobj is "this" object.
aobj.set<jni::jobject>(bobj, "b"); // Set variable "b" on aobj to bobj.
}This is the equivalent of:
void doStuff(b bobj)
{
this.b = bobj;
}from jnipp.
