  - ### Method Detail

    - #### parse

          public BeanDefinition parse(Element element,
                             ParserContext parserContext)

      Description copied from interface: `BeanDefinitionParser`
      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.

      Specified by:
        `parse` in interface `BeanDefinitionParser`
      Parameters:
        `element` - the element that is to be parsed into one or more `BeanDefinitions`
        `parserContext` - the object encapsulating the current state of the parsing process; provides access to a `BeanDefinitionRegistry`
      Returns:
        the primary `BeanDefinition`
