public class RootBeanDefinition
extends AbstractBeanDefinition
```
A root bean definition represents the merged bean definition that backs a specific bean in a Spring BeanFactory at runtime. It might have been created from multiple original bean definitions that inherit from each other, typically registered as GenericBeanDefinitions. A root bean definition is essentially the 'unified' bean definition view at runtime.
Root bean definitions may also be used for registering individual bean definitions in the configuration phase. However, since Spring 2.5, the preferred way to register bean definitions programmatically is the GenericBeanDefinition class. GenericBeanDefinition has the advantage that it allows to dynamically define parent dependencies, not 'hard-coding' the role as a root bean definition.
