Question

我有一个具有以下结构和以下自定义注释的枚举类：

enum class Feature() {
    @TypeBoolean EnableFeatureA,
    @TypeBoolean EnableFeatureB,
    @TypeInt FeatureAValue,
    @TypeString FeatureBValue
}

@Target(AnnotationTarget.PROPERTY, AnnotationTarget.FIELD)
@Retention(AnnotationRetention.RUNTIME)
annotation class TypeBoolean

@Target(AnnotationTarget.PROPERTY, AnnotationTarget.FIELD)
@Retention(AnnotationRetention.RUNTIME)
annotation class TypeString

@Target(AnnotationTarget.PROPERTY, AnnotationTarget.FIELD)
@Retention(AnnotationRetention.RUNTIME)
annotation class TypeInt

然后我会有类似以下内容的吸气剂：

fun getFeatureBoolean(feature: Feature): Boolean {
    return featureSet.getBoolean(feature)
}

fun getFeatureString(feature: Feature): String {
    return featureSet.getString(feature)
}

fun getFeatureInt(feature: Feature): Int {
    return featureSet.getInt(feature)
}

我不希望可为null的类型或回退，因为我知道数据将在那里。我只是想确保不会传递错误类型的标签。

我已经知道如何检查成员是否具有带有验证器的注释；我缺少的是如何在编译时而不是运行时检查。
