类 MergedAnnotationCollectors

方法详细资料

• toAnnotationSet

  public static <A extends Annotation> Collector<MergedAnnotation<A>,​?,​Set<A>> toAnnotationSet()

  Create a new Collector that accumulates merged annotations to a LinkedHashSet containing synthesized versions.

  The collector returned by this method is effectively equivalent to Collectors.mapping(MergedAnnotation::synthesize, Collectors.toCollection(LinkedHashSet::new)) but avoids the creation of a composite collector.

  类型参数:

  A - the annotation type

  返回:

  a Collector which collects and synthesizes the annotations into a Set

• toAnnotationArray

  public static <A extends Annotation> Collector<MergedAnnotation<A>,​?,​Annotation[]> toAnnotationArray()

  Create a new Collector that accumulates merged annotations to an Annotation array containing synthesized versions.

  类型参数:

  A - the annotation type

  返回:

  a Collector which collects and synthesizes the annotations into an Annotation[]

• toAnnotationArray

  public static <R extends Annotation,​A extends R> Collector<MergedAnnotation<A>,​?,​R[]> toAnnotationArray​(IntFunction<R[]> generator)

  Create a new Collector that accumulates merged annotations to an Annotation array containing synthesized versions.

  类型参数:

  A - the annotation type

  R - the resulting array type

  参数:

  generator - a function which produces a new array of the desired type and the provided length

  返回:

  a Collector which collects and synthesizes the annotations into an annotation array

• toMultiValueMap

  public static <A extends Annotation> Collector<MergedAnnotation<A>,​?,​MultiValueMap<String,​Object>> toMultiValueMap​(MergedAnnotation.Adapt... adaptations)

  Create a new Collector that accumulates merged annotations to a MultiValueMap with items added from each merged annotation as a map.

  类型参数:

  A - the annotation type

  参数:

  adaptations - the adaptations that should be applied to the annotation values

  返回:

  a Collector which collects and synthesizes the annotations into a LinkedMultiValueMap

  toMultiValueMap(Function, MergedAnnotation.Adapt...)

• toMultiValueMap

  public static <A extends Annotation> Collector<MergedAnnotation<A>,​?,​MultiValueMap<String,​Object>> toMultiValueMap​(Function<MultiValueMap<String,​Object>,​MultiValueMap<String,​Object>> finisher,
                                                                                                                                       MergedAnnotation.Adapt... adaptations)

  Create a new Collector that accumulates merged annotations to a MultiValueMap with items added from each merged annotation as a map.

  类型参数:

  A - the annotation type

  参数:

  finisher - the finisher function for the new MultiValueMap

  adaptations - the adaptations that should be applied to the annotation values

  返回:

  a Collector which collects and synthesizes the annotations into a LinkedMultiValueMap
