Class RootBeanDefinition
- All Implemented Interfaces:
Serializable
,Cloneable
,BeanMetadataElement
,BeanDefinition
,AttributeAccessor
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.
