Class AnnotationMergeCollector

  • All Implemented Interfaces:
    java.util.stream.Collector<java.lang.annotation.Annotation,​java.util.Map<java.lang.String,​java.lang.Object>,​java.util.Map<java.lang.String,​java.lang.Object>>
    public class AnnotationMergeCollector
extends java.lang.Object
implements java.util.stream.Collector<java.lang.annotation.Annotation,​java.util.Map<java.lang.String,​java.lang.Object>,​java.util.Map<java.lang.String,​java.lang.Object>>
    merge annotations by mapping ReflectionUtils.toMap(Annotation) and reduce using the given mergeFunction

    mergeFunction defaults to concatValues(Object, Object).

    optional annotatedElement used by ReflectionUtils.toMap(Annotation, AnnotatedElement) 

    get(Annotations.of(...))
   .stream()
   .collect(new AnnotationMergeCollector())
