Interface BeanDefinition

All Known Implementing Classes:

AbstractBeanDefinition, ChildBeanDefinition, RootBeanDefinition

public interface BeanDefinition

A BeanDefinition describes a bean instance, which has property values, constructor argument values, and further information supplied by concrete implementations.

This is just a minimal interface: The main intention is to allow BeanFactoryPostProcessors (like PropertyPlaceholderConfigurer) to access and modify property values.

Method Summary

ConstructorArgumentValues	getConstructorArgumentValues() Return the constructor argument values for this bean, if any.
MutablePropertyValues	getPropertyValues() Return the PropertyValues to be applied to a new instance of the bean, if any.
String	getResourceDescription() Return a description of the resource that this bean definition came from (for the purpose of showing context in case of errors).
boolean	isAbstract() Return whether this bean is "abstract", i.e. not meant to be instantiated.
boolean	isLazyInit() Return whether this bean should be lazily initialized, i.e. not eagerly instantiated on startup.
boolean	isSingleton() Return whether this a Singleton, with a single, shared instance returned on all calls.

Method Detail

isAbstract

boolean isAbstract()

Return whether this bean is "abstract", i.e. not meant to be instantiated.

isSingleton

boolean isSingleton()

Return whether this a Singleton, with a single, shared instance returned on all calls.

Returns:

the ConstructorArgumentValues object, or null

getResourceDescription

String getResourceDescription()
