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.

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:
