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 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
    See Also:
    generateBeanName(BeanDefinition, BeanDefinitionRegistry, boolean)
  - 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
  - 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(AbstractBeanDefinition 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
