public interface BeanDefinitionRegistry
extends AliasRegistry
```
Interface for registries that hold bean definitions, for example RootBeanDefinition and ChildBeanDefinition instances. Typically implemented by BeanFactories that internally work with the AbstractBeanDefinition hierarchy.
This is the only interface in Spring's bean factory packages that encapsulates registration of bean definitions. The standard BeanFactory interfaces only cover access to a fully configured factory instance.
Spring's bean definition readers expect to work on an implementation of this interface. Known implementors within the Spring core are DefaultListableBeanFactory and GenericApplicationContext.

  - registerBeanDefinition
```
void registerBeanDefinition(String beanName,
                            BeanDefinition beanDefinition)
                     throws BeanDefinitionStoreException
```
    Register a new bean definition with this registry. Must support RootBeanDefinition and ChildBeanDefinition.
    Parameters:
    beanName - the name of the bean instance to register
    beanDefinition - definition of the bean instance to register
    Throws:
    BeanDefinitionStoreException - if the BeanDefinition is invalid
    BeanDefinitionOverrideException - if there is already a BeanDefinition for the specified bean name and we are not allowed to override it

    GenericBeanDefinition, RootBeanDefinition, ChildBeanDefinition
  - removeBeanDefinition
```
void removeBeanDefinition(String beanName)
                   throws NoSuchBeanDefinitionException
```
    Remove the BeanDefinition for the given name.
    Parameters:
    beanName - the name of the bean instance to register
    Throws:
    NoSuchBeanDefinitionException - if there is no such bean definition
  - getBeanDefinition
```
BeanDefinition getBeanDefinition(String beanName)
                          throws NoSuchBeanDefinitionException
```
    Return the BeanDefinition for the given bean name.
    Parameters:
    beanName - name of the bean to find a definition for
    Returns:
    the BeanDefinition for the given name (never null)
    Throws:
    NoSuchBeanDefinitionException - if there is no such bean definition
  - containsBeanDefinition
```
boolean containsBeanDefinition(String beanName)
```
    Check if this registry contains a bean definition with the given name.
    Parameters:
    beanName - the name of the bean to look for
    Returns:
    if this registry contains a bean definition with the given name
  - getBeanDefinitionNames
```
String[] getBeanDefinitionNames()
```
    Return the names of all beans defined in this registry.
    Returns:
    the names of all beans defined in this registry, or an empty array if none defined
  - getBeanDefinitionCount
```
int getBeanDefinitionCount()
```
    Return the number of beans defined in the registry.
    Returns:
    the number of beans defined in the registry
  - isBeanNameInUse
```
boolean isBeanNameInUse(String beanName)
```
    Determine whether the given bean name is already in use within this registry, i.e. whether there is a local bean or alias registered under this name.
    Parameters:
    beanName - the name to check
    Returns:
    whether the given bean name is already in use
