| // 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 (or other files in this directory) 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). |
