使用枚举的节俭常量结构答案

【问题标题】：thrift constant structure using enum使用枚举的节俭常量结构
【发布时间】：2014-03-12 14:28:40
【问题描述】：

我有以下枚举，并想使用此枚举的元素创建一个常量映射：

enum UploadFileType {
    POPULATION,
    PROBABILITY,
    REACH,
    CMOBILE,
    CMOBAPP
}

/**
 * Defines which files are uploadable in which country
 */
const map<string,list<UploadFileType>> uploadable_files = {
    'hu': [POPULATION, PROBABILITY, REACH, CMOBILE, CMOBAPP],
    'sk': [POPULATION, PROBABILITY, REACH]
}

我在这里遇到以下错误：

[FAILURE:/home/abc/internal.thrift:29] error: identifier POPULATION is unqualified!
[FAILURE:/home/abc/internal.thrift:29] error: identifier POPULATION is unqualified!

我不知道这应该怎么看。

错误说它相当准确。

【解决方案1】：

枚举使用点表示法：

const map<string,list<UploadFileType>> uploadable_files = {
    'hu': [UploadFileType.POPULATION, UploadFileType.PROBABILITY, UploadFileType.REACH, UploadFileType.CMOBILE, UploadFileType.CMOBAPP],
    'sk': [UploadFileType.POPULATION, UploadFileType.PROBABILITY, UploadFileType.REACH]
}

【解决方案2】：

enum UploadFileType {
    POPULATION,
    PROBABILITY,
    REACH,
    CMOBILE,
    CMOBAPP
}

/**
 * Defines which files are uploadable in which country
 */
const map<string,list<UploadFileType>> uploadable_files = {
    'hu': [UploadFileType.POPULATION, UploadFileType.PROBABILITY, UploadFileType.REACH, UploadFileType.CMOBILE, UploadFileType.CMOBAPP],
    'sk': [UploadFileType.POPULATION, UploadFileType.PROBABILITY, UploadFileType.REACH]
}
