Direct Known Subclasses:

ChildBeanDefinition, RootBeanDefinition

public abstract class AbstractBeanDefinition

extends java.lang.Object

Internal BeanFactory implementation class. This abstract base class defines the BeanFactory type.Use a FactoryBean to customize behaviour when returning application beans.

A BeanDefinition describes a bean instance, which has property values and further information supplied by concrete classes or subinterfaces.

Once configuration is complete, a BeanFactory will be able to return direct references to objects defined by BeanDefinitions.

Creates new BeanDefinition

Parameters:

pvs - properties of the bean

Method Detail

isSingleton

public final boolean isSingleton()

Is this a Singleton, with a single, shared instance returned on all calls, or should the BeanFactory apply the Prototype design pattern, with each caller requesting an instance getting an independent instance? How this is defined will depend on the BeanFactory. "Singletons" are the commoner type.

Returns:

whether this is a Singleton

setPropertyValues

public void setPropertyValues(PropertyValues pvs)

getPropertyValues

public PropertyValues getPropertyValues()

Return the PropertyValues to be applied to a new instance of this bean.

Returns:

the PropertyValues to be applied to a new instance of this bean
