Constructor Detail

AbstractBeanDefinition

protected AbstractBeanDefinition(MutablePropertyValues pvs)

Create a new bean definition.

Parameters:

pvs - the PropertyValues to be applied to a new instance of the bean

Method Detail

getPropertyValues

public MutablePropertyValues getPropertyValues()

Description copied from interface: BeanDefinition

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

Specified by:

getPropertyValues in interface BeanDefinition

getConstructorArgumentValues

public ConstructorArgumentValues getConstructorArgumentValues()

This implementations returns null: Just RootBeanDefinitions have concrete support for constructor argument values.

Specified by:

getConstructorArgumentValues in interface BeanDefinition

setResourceDescription

public void setResourceDescription(java.lang.String resourceDescription)

Set a description of the resource that this bean definition came from (for the purpose of showing context in case of errors).

getResourceDescription

public java.lang.String getResourceDescription()

Description copied from interface: BeanDefinition

Return a description of the resource that this bean definition came from (for the purpose of showing context in case of errors).

Specified by:

getResourceDescription in interface BeanDefinition

setSingleton

public void setSingleton(boolean singleton)

Set if this a Singleton, with a single, shared instance returned on all calls. If false, the BeanFactory will 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.

isSingleton

public boolean isSingleton()

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

setLazyInit

public void setLazyInit(boolean lazyInit)

Set whether this bean should be lazily initialized. Only applicable to a singleton bean. If false, it will get instantiated on startup by bean factories that perform eager initialization of singletons.

isLazyInit

public boolean isLazyInit()

Return whether this bean should be lazily initialized.

validate

public void validate()
              throws BeanDefinitionValidationException

Validate this bean definition.

Throws:

BeanDefinitionValidationException - in case of validation failure
