Interface SynthesizedAnnotationSelector

All Known Implementing Classes:

SynthesizedAnnotationSelector.FarthestAndNewestPrioritySelector, SynthesizedAnnotationSelector.FarthestAndOldestPrioritySelector, SynthesizedAnnotationSelector.NearestAndNewestPrioritySelector, SynthesizedAnnotationSelector.NearestAndOldestPrioritySelector

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SynthesizedAnnotationSelector

注解选择器，指定两个注解，选择其中一个返回。
该接口用于在SynthesizedAggregateAnnotation中用于从一批相同的注解对象中筛选最终用于合成注解对象。
