Class BeanDefinitionHolder

org.springframework.beans.factory.config.BeanDefinitionHolder

All Implemented Interfaces:

BeanMetadataElement

Direct Known Subclasses:

BeanComponentDefinition

public class BeanDefinitionHolder
extends java.lang.Object
implements BeanMetadataElement

Holder for a BeanDefinition with name and aliases. Can be registered as a placeholder for an inner bean.

Can also be used for programmatic registration of inner bean definitions. If you don't care about BeanNameAware and the like, registering RootBeanDefinition or ChildBeanDefinition is good enough.
