-/**
- * The CallbackBase class is used internally by the NeuralNetworks runtime to
- * synchronize between different threads. An asynchronous task is launched
- * paired with a callback object. When a client thread requires the output being
- * generated by the asynchronous task, the client thread can wait for the result
- * and be blocked until it has completed or a timeout condition has been
- * reached. Any wait* may safely be called concurrently, even on the same
- * callback object. When the asynchronous task has finished its workload, it
- * must immediately call "notify". If the asynchronous task has failed to launch,
- * the function that tried to launch the asynchronous task must immediately call
- * "notify". This "notify" call awakens any client threads waiting on the
- * callback object.
- *
- * The CallbackBase class implements some of the base synchronization common to
- * both PrepareModelCallback and ExecutionCallback. For consistency, any HIDL
- * callback class must inherit from CallbackBase as well as the HIDL callback
- * interface it implements.
- *
- * This class exists to enable synchronization across HIDL. When synchronization
- * is only required in the same process, consider using std::future, std::mutex,
- * std::condition_variable, or std::experimental::latch instead.
