/**
* Post-processor callback interface for merged bean definitions at runtime.
* {@link BeanPostProcessor} implementations may implement this sub-interface in order
* to post-process the merged bean definition (a processed copy of the original bean
* definition) that the Infra {@code BeanFactory} uses to create a bean instance.
*
* The {@link #postProcessMergedBeanDefinition} method may for example introspect
* the bean definition in order to prepare some cached metadata before post-processing
* actual instances of a bean. It is also allowed to modify the bean definition but
* only for definition properties which are actually intended for concurrent
* modification. Essentially, this only applies to operations defined on the
* {@link RootBeanDefinition} itself but not to the properties of its base classes.
