    `ClassLoader` | `getAspectClassLoader()` Expose the aspect class loader that this factory uses.
    `Object` | `getAspectInstance()` Look up the aspect bean from the `BeanFactory` and returns it.
    `int` | `getOrder()` Return the order value of this object, with a higher value meaning greater in terms of sorting.
    `void` | `setAspectBeanName(String aspectBeanName)` Set the name of the aspect bean.
    `void` | `setBeanFactory(BeanFactory beanFactory)` Callback that supplies the owning factory to a bean instance.

          public SimpleBeanFactoryAwareAspectInstanceFactory()

  - ### Method Detail

    - #### setAspectBeanName

          public void setAspectBeanName(String aspectBeanName)

      Set the name of the aspect bean. This is the bean that is returned when calling `getAspectInstance()`.

    - #### setBeanFactory

          public void setBeanFactory(BeanFactory beanFactory)

      Description copied from interface: `BeanFactoryAware`
      Callback that supplies the owning factory to a bean instance.

      Invoked after the population of normal bean properties but before an initialization callback such as `InitializingBean.afterPropertiesSet()` or a custom init-method.

      Specified by:
        `setBeanFactory` in interface `BeanFactoryAware`
      Parameters:
        `beanFactory` - owning BeanFactory (never `null`). The bean can immediately call methods on the factory.
      See Also:
        `BeanInitializationException`

    - #### getAspectInstance

          public Object getAspectInstance()

      Look up the aspect bean from the `BeanFactory` and returns it.
      Specified by:
        `getAspectInstance` in interface `AspectInstanceFactory`
      Returns:
        the aspect instance (never `null`)
      See Also:
        `setAspectBeanName(java.lang.String)`

    - #### getAspectClassLoader

          public ClassLoader getAspectClassLoader()

      Description copied from interface: `AspectInstanceFactory`
      Expose the aspect class loader that this factory uses.
      Specified by:
        `getAspectClassLoader` in interface `AspectInstanceFactory`
      Returns:
        the aspect class loader (never `null`)

    - #### getOrder

          public int getOrder()

      Description copied from interface: `Ordered`
      Return the order value of this object, with a higher value meaning greater in terms of sorting.

      Normally starting with 0, with `Integer.MAX_VALUE` indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

      Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

      Specified by:
        `getOrder` in interface `Ordered`
      Returns:
        the order value
