an annotation mirror of class anno on elt, or an equivalent one, or null if none exists on anno

getAnnotationMirror

public javax.lang.model.element.AnnotationMirror getAnnotationMirror(com.sun.source.tree.Tree tree,
                                                                     java.lang.Class<? extends java.lang.annotation.Annotation> target)

target - the class of the annotation

Returns:

the annotation on tree that has the class target, or null
