| // 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). |
