Adapter that implements all methods on SmartInstantiationAwareBeanPostProcessor as no-ops, which will not change normal processing of each bean instantiated by the container. Subclasses may override merely those methods that they are actually interested in. 
Note that this base class is only recommendable if you actually require InstantiationAwareBeanPostProcessor functionality. If all you need is plain BeanPostProcessor functionality, prefer a straight implementation of that (simpler) interface.
