All Implemented Interfaces:
BeanDefinition

public class ChildBeanDefinition
extends AbstractBeanDefinition

Bean definition for beans who inherit settings from their parent.

Will use the bean class of the parent if none specified, but can also override it. In the latter case, the child bean class must be compatible with the parent, i.e. accept the parent's property values and constructor argument values, if any.

A child bean definition will inherit constructor argument values, property values and method overrides from the parent, with the option to add new values. If init method, destroy method and/or static factory method are specified, they will override the corresponding parent settings.

The remaining settings will always be taken from the child definition: depends on, autowire mode, dependency check, singleton, lazy init.

Constructor Detail

ChildBeanDefinition

public ChildBeanDefinition(String parentName,
                           MutablePropertyValues pvs)
Create a new ChildBeanDefinition for the given parent.

Parameters:
parentName - the name of the parent bean
pvs - the additional property values of the child

ChildBeanDefinition

public ChildBeanDefinition(String parentName,
                           ConstructorArgumentValues cargs,
                           MutablePropertyValues pvs)
Create a new ChildBeanDefinition for the given parent.

Parameters:
parentName - the name of the parent bean
cargs - the constructor argument values to apply
pvs - the additional property values of the child

ChildBeanDefinition

public ChildBeanDefinition(String parentName,
                           Class beanClass,
                           ConstructorArgumentValues cargs,
                           MutablePropertyValues pvs)
Create a new ChildBeanDefinition for the given parent, providing constructor arguments and property values.

Parameters:
parentName - the name of the parent bean
beanClass - the class of the bean to instantiate
cargs - the constructor argument values to apply
pvs - the property values to apply

ChildBeanDefinition

public ChildBeanDefinition(String parentName,
                           String beanClassName,
                           ConstructorArgumentValues cargs,
                           MutablePropertyValues pvs)
Create a new ChildBeanDefinition for the given parent, providing constructor arguments and property values. Takes a bean class name to avoid eager loading of the bean class.

Parameters:
parentName - the name of the parent bean
beanClassName - the name of the class to instantiate
cargs - the constructor argument values to apply
pvs - the property values to apply
Method Detail

getParentName

validate

public void validate()
              throws BeanDefinitionValidationException
Description copied from class: AbstractBeanDefinition
Validate this bean definition.

Overrides:
validate in class AbstractBeanDefinition
Throws:
BeanDefinitionValidationException - in case of validation failure
