Class AnnotationMergeCollector

java.lang.Object

org.reflections.util.AnnotationMergeCollector

All Implemented Interfaces:

Collector<Annotation,Map<String,Object>,Map<String,Object>>

public class AnnotationMergeCollector
extends Object
implements Collector<Annotation,Map<String,Object>,Map<String,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())
