Examples of org.voltdb.jni.ExecutionEngineJNI

org.voltdb.jni.ExecutionEngineJNI
Wrapper for native Execution Engine library. All native methods are private to make it simple and keep Java/C++ separated as much as possible. These native methods basically just receive IDs in primitive types to simplify JNI calls. This is why these native methods are private and we have public methods that receive objects for type-safety. For each methods, see comments in hstorejni.cpp. Read com.horinzontica.jni for guidelines to add/modify JNI methods.
