Method Detail

createBeanDefinition

public static AbstractBeanDefinition createBeanDefinition(String parentName,
                                                          String className,
                                                          ClassLoader classLoader)
                                                   throws ClassNotFoundException
Create a new GenericBeanDefinition for the given parent name and class name, eagerly loading the bean class if a ClassLoader has been specified.

Parameters:
parentName - the name of the parent bean, if any
className - the name of the bean class, if any
classLoader - the ClassLoader to use for loading bean classes (can be null to just register bean classes by name)
Returns:
the bean definition
Throws:
ClassNotFoundException - if the bean class could not be loaded

generateBeanName

public static String generateBeanName(BeanDefinition definition,
                                      BeanDefinitionRegistry registry,
                                      boolean isInnerBean)
                               throws BeanDefinitionStoreException
Generate a bean name for the given bean definition, unique within the given bean factory.

Parameters:
definition - the bean definition to generate a bean name for
registry - the bean factory that the definition is going to be registered with (to check for existing bean names)
isInnerBean - whether the given bean definition will be registered as inner bean or as top-level bean (allowing for special name generation for inner beans versus top-level beans)
Returns:
the generated bean name
Throws:
BeanDefinitionStoreException - if no unique name can be generated for the given bean definition

generateBeanName

public static String generateBeanName(BeanDefinition beanDefinition,
                                      BeanDefinitionRegistry registry)
                               throws BeanDefinitionStoreException
Generate a bean name for the given top-level bean definition, unique within the given bean factory.

Parameters:
beanDefinition - the bean definition to generate a bean name for
registry - the bean factory that the definition is going to be registered with (to check for existing bean names)
Returns:
the generated bean name
Throws:
BeanDefinitionStoreException - if no unique name can be generated for the given bean definition

registerBeanDefinition

public static void registerBeanDefinition(BeanDefinitionHolder definitionHolder,
                                          BeanDefinitionRegistry registry)
                                   throws BeanDefinitionStoreException
Register the given bean definition with the given bean factory.

Parameters:
definitionHolder - the bean definition including name and aliases
registry - the bean factory to register with
Throws:
BeanDefinitionStoreException - if registration failed

registerWithGeneratedName

public static String registerWithGeneratedName(BeanDefinition definition,
                                               BeanDefinitionRegistry registry)
                                        throws BeanDefinitionStoreException
Register the given bean definition with a generated name, unique within the given bean factory.

Parameters:
definition - the bean definition to generate a bean name for
registry - the bean factory to register with
Returns:
the generated bean name
Throws:
BeanDefinitionStoreException - if no unique name can be generated for the given bean definition or the definition cannot be registered

registerWithGeneratedName

@Deprecated
public static String registerWithGeneratedName(AbstractBeanDefinition definition,
                                                          BeanDefinitionRegistry registry)
