+ * No thread safety is required.
+ *
+ * For instance, imagine if we have this interface:
+ * interface IFoo { void doFoo(); }

+ * A). Historical option that has proven to be BAD! Only the original
+ * author of an interface should change an interface. If someone

+ * 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:
+ * std::shared_ptr<MyFoo> foo = new MyFoo; // class in AOSP codebase
+ * std::shared_ptr<MyBar> bar = new MyBar; // custom extension class
+ * ... = AIBinder_setExtension(foo->asBinder().get(), bar->asBinder().get());
+ * // handle error
+ *
+ * Then, clients of IFoo can get this extension:
+ * SpAIBinder binder = ...;
+ * std::shared_ptr<IFoo> foo = IFoo::fromBinder(binder); // handle if null
+ * SpAIBinder barBinder;
+ * ... = AIBinder_getExtension(barBinder.get());
+ * // handle error
+ * std::shared_ptr<IBar> bar = IBar::fromBinder(barBinder);
+ * // type is checked with AIBinder_associateClass
+ * // if bar is null, then there is no extension or a different
+ * // type of extension
+ *
+ * \param binder the object to get the extension on. Must be local.
