typescript - TsLint 说 "expected callSignature to have a typedef."是什么意思

Question

我的代码中有一个函数:

networkStop = (action: string = null) => {
    this.action[action] = false;
    this.net = false;
    this.netd = false;
}

我收到 TsLint 错误提示:

Message 4   TsLint: expected callSignature to have a typedef.

谁能解释一下这是什么意思？

“缺少类型定义”请参阅:https://github.com/palantir/tslint/blob/master/src/rules/typedefRule.ts了解详情。基本上 一些 注释(对于一个函数，因为 callSignature)丢失了。

可能是修复(明确指定返回类型):

networkStop = (action: string = null):void => {
    this.action[action] = false;
    this.net = false;
    this.netd = false;
}
