Class ConfigurationClassBeanDefinitionReader

java.lang.Object

org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader

class ConfigurationClassBeanDefinitionReader
extends java.lang.Object

Reads a given fully-populated set of ConfigurationClass instances, registering bean definitions with the given BeanDefinitionRegistry based on its contents.

This class was modeled after the BeanDefinitionReader hierarchy, but does not implement/extend any of its artifacts as a set of configuration classes is not a Resource.

Since:

3.0
