parse	back to summary
public final BeanDefinition parse(Element element, ParserContext parserContext) Implements org.springframework.beans.factory.xml.BeanDefinitionParser.parse. Doc from org.springframework.beans.factory.xml.BeanDefinitionParser.parse. Parse the specified `Element` and register the resulting `BeanDefinition(s)` with the `BeanDefinitionRegistry` embedded in the supplied `ParserContext`. Implementations must return the primary `BeanDefinition` that results from the parse if they will ever be used in a nested fashion (for example as an inner tag in a `<property/>` tag). Implementations may return `null` if they will not be used in a nested fashion. Parameters element:Element the element that is to be parsed into one or more `BeanDefinitions` parserContext:ParserContext the object encapsulating the current state of the parsing process; provides access to a `org.springframework.beans.factory.support.BeanDefinitionRegistry` Returns:BeanDefinition the primary `BeanDefinition` Annotations @Override @Nullable

postProcessComponentDefinition back to summary

postProcessComponentDefinition	back to summary
protected void postProcessComponentDefinition(BeanComponentDefinition componentDefinition) Hook method called after the primary parsing of a `BeanComponentDefinition` but before the `BeanComponentDefinition` has been registered with a `org.springframework.beans.factory.support.BeanDefinitionRegistry`. Derived classes can override this method to supply any custom logic that is to be executed after all the parsing is finished. The default implementation is a no-op. Parameters componentDefinition:BeanComponentDefinition the `BeanComponentDefinition` that is to be processed

protected void postProcessComponentDefinition(BeanComponentDefinition componentDefinition)

Hook method called after the primary parsing of a BeanComponentDefinition but before the BeanComponentDefinition has been registered with a org.springframework.beans.factory.support.BeanDefinitionRegistry.

Derived classes can override this method to supply any custom logic that is to be executed after all the parsing is finished.

The default implementation is a no-op.

Parameters

componentDefinition:BeanComponentDefinition: the BeanComponentDefinition that is to be processed

registerBeanDefinition back to summary

registerBeanDefinition	back to summary
protected void registerBeanDefinition(BeanDefinitionHolder definition, BeanDefinitionRegistry registry) Register the supplied `bean` with the supplied `registry`. Subclasses can override this method to control whether the supplied `bean` is actually even registered, or to register even more beans. The default implementation registers the supplied `bean` with the supplied `registry` only if the `isNested` parameter is `false`, because one typically does not want inner beans to be registered as top level beans. Parameters definition:BeanDefinitionHolder the bean definition to be registered registry:BeanDefinitionRegistry the registry that the bean is to be registered with See Also `BeanDefinitionReaderUtils#registerBeanDefinition(BeanDefinitionHolder, BeanDefinitionRegistry)`

protected void registerBeanDefinition(BeanDefinitionHolder definition, BeanDefinitionRegistry registry)

Subclasses can override this method to control whether the supplied bean is actually even registered, or to register even more beans.

The default implementation registers the supplied bean with the supplied registry only if the isNested parameter is false, because one typically does not want inner beans to be registered as top level beans.

Parameters

definition:BeanDefinitionHolder: the bean definition to be registered
registry:BeanDefinitionRegistry: the registry that the bean is to be registered with

resolveId back to summary

resolveId	back to summary
protected String resolveId(Element element, AbstractBeanDefinition definition, ParserContext parserContext) throws BeanDefinitionStoreException Resolve the ID for the supplied `BeanDefinition`. When using `generation`, a name is generated automatically. Otherwise, the ID is extracted from the "id" attribute, potentially with a `fallback` to a generated id. Parameters element:Element the element that the bean definition has been built from definition:AbstractBeanDefinition the bean definition to be registered parserContext:ParserContext the object encapsulating the current state of the parsing process; provides access to a `org.springframework.beans.factory.support.BeanDefinitionRegistry` Returns:String the resolved id Exceptions BeanDefinitionStoreException: if no unique name could be generated for the given bean definition

protected String resolveId(Element element, AbstractBeanDefinition definition, ParserContext parserContext) throws BeanDefinitionStoreException

Resolve the ID for the supplied BeanDefinition.

When using generation, a name is generated automatically. Otherwise, the ID is extracted from the "id" attribute, potentially with a fallback to a generated id.

Parameters

element:Element: the element that the bean definition has been built from
definition:AbstractBeanDefinition: the bean definition to be registered
parserContext:ParserContext: the object encapsulating the current state of the parsing process; provides access to a org.springframework.beans.factory.support.BeanDefinitionRegistry

shouldGenerateIdAsFallback back to summary

shouldGenerateIdAsFallback	back to summary
protected boolean shouldGenerateIdAsFallback() Should an ID be generated instead if the passed in `Element` does not specify an "id" attribute explicitly? Disabled by default; subclasses can override this to enable ID generation as fallback: The parser will first check for an "id" attribute in this case, only falling back to a generated ID if no value was specified. Returns:boolean whether the parser should generate an id if no id was specified

protected boolean shouldGenerateIdAsFallback()

Should an ID be generated instead if the passed in Element does not specify an "id" attribute explicitly?

Disabled by default; subclasses can override this to enable ID generation as fallback: The parser will first check for an "id" attribute in this case, only falling back to a generated ID if no value was specified.
