- - ### Element Detail

    - #### value

          public abstract Class<?>[] value

      The class or classes to use as the filter. In the case of `FilterType.ANNOTATION`, the class will be the annotation itself. In the case of `FilterType.ASSIGNABLE_TYPE`, the class will be the type that detected components should be assignable to. And in the case of `FilterType.CUSTOM`, the class will be an implementation of `TypeFilter`.

      When multiple classes are specified, OR logic is applied, e.g. "include types annotated with `@Foo` OR `@Bar`".

      Specifying zero classes is permitted but will have no effect on component scanning.

    - #### type

          public abstract FilterType type

      The type of filter to use.

      Note that the filter types available are limited to those that may be expressed as a `Class` in the `value()` attribute. This is in contrast to `<context:component-scan/>`, which allows for expression-based (i.e., string-based) filters such as AspectJ pointcuts. These filter types are intentionally not supported here, and not available in the `FilterType` enum.
