/**
 * Adapter that implements all methods on {@link 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.
 *
 * <p>Note that this base class is only recommendable if you actually require
 * {@link InstantiationAwareBeanPostProcessor} functionality. If all you need
 * is plain {@link BeanPostProcessor} functionality, prefer a straight
 * implementation of that (simpler) interface.
