stream

public <A extends Annotation>

Stream all annotations and meta-annotations that match the specified type. The resulting stream follows the same ordering rules as MergedAnnotations.stream().

a stream of matching annotations

stream

stream

public Stream<MergedAnnotation<Annotation>> stream()

从接口复制的说明: MergedAnnotations

Stream all annotations and meta-annotations contained in this collection. The resulting stream is ordered first by the aggregate index and then by the annotation distance (with the closest annotations first). This ordering means that, for most use-cases, the most suitable annotations appear earliest in the stream.

 @Nullable
 Object requiredType)

valueOf

static MergedAnnotations valueOf(@Nullable
 Collection<MergedAnnotation<?>> annotations)

从接口复制的说明: MergedAnnotations

Create a new MergedAnnotations instance from the specified collection of directly present annotations. This method allows a MergedAnnotations instance to be created from annotations that are not necessarily loaded using reflection. The provided annotations must all be directly present and must have an aggregate index of 0.

The resulting MergedAnnotations instance will contain both the specified annotations, and any meta-annotations that can be read using reflection.

参数:

annotations - the annotations to include

返回:

a MergedAnnotations instance containing the annotations
