Interface BeanDefinition

All Known Implementing Classes:

BeanDefinitionImpl

public interface BeanDefinition

Defines the URL, class name, scope and initial properties for a bean. All beans managed by the BeanFactory container must be defined by an implementation of this interface. This interface is exposed through the DefinitionLoader interface.

Normal use of the BeanFactory framework should not involve direct interaction with this class.
