// Hints for future visitors:
// This entire file is an implementation detail of the org.webrtc Java package,
// the most interesting bits of which are org.webrtc.PeerConnection{,Factory}.
// The layout of this file is roughly:
// - various helper C++ functions & classes that wrap Java counterparts and
// expose a C++ interface that can be passed to the C++ PeerConnection APIs
// - implementations of methods declared "static" in the Java package (named
// things like Java_org_webrtc_OMG_Can_This_Name_Be_Any_Longer, prescribed by
// the JNI spec).
//
// Lifecycle notes: objects are owned where they will be called; in other words
// FooObservers are owned by C++-land, and user-callable objects (e.g.
// PeerConnection and VideoTrack) are owned by Java-land.
// When this file allocates C++ RefCountInterfaces it AddRef()s an artificial
// ref simulating the jlong held in Java-land, and then Release()s the ref in
// the respective free call. Sometimes this AddRef is implicit in the
// construction of a scoped_refptr<> which is then .release()d.
// Any persistent (non-local) references from C++ to Java must be global or weak
// (in which case they must be checked before use)!
//
// Exception notes: pretty much all JNI calls can throw Java exceptions, so each
// call through a JNIEnv* pointer needs to be followed by an ExceptionCheck()
// call. In this file this is done in CHECK_EXCEPTION, making for much easier
// debugging in case of failure (the alternative is to wait for control to
// return to the Java frame that called code in this file, at which point it's
// impossible to tell which JNI call broke).
