- * If an unrelated owner (perhaps in a downstream codebase) wants to make a
- * change to the interface, they have two options:
- *
- * A). Historical option that has proven to be BAD! Only the original

- * downstream wants additional functionality, they should not ever
- * change the interface or use this method.
- *
- * BAD TO DO: interface IFoo { BAD TO DO
- * BAD TO DO: void doFoo(); BAD TO DO
- * BAD TO DO: + void doBar(); // adding a method BAD TO DO
- * BAD TO DO: } BAD TO DO
- *
- * B). Option that this method enables!
- * Leave the original interface unchanged (do not change IFoo!).
- * Instead, create a new interface in a downstream package:
- *
- * package com.<name>; // new functionality in a new package
- * interface IBar { void doBar(); }
- *
- * When registering the interface, add:
- * sp<MyFoo> foo = new MyFoo; // class in AOSP codebase
- * sp<MyBar> bar = new MyBar; // custom extension class
- * foo->setExtension(bar); // use method in BBinder
- *
- * Then, clients of IFoo can get this extension:
- * sp<IBinder> binder = ...;
- * sp<IFoo> foo = interface_cast<IFoo>(binder); // handle if null
- * sp<IBinder> barBinder;
- * ... handle error ... = binder->getExtension(&barBinder);
