循环遍历类的所有成员

发布于 2025-01-11 05:02:35 字数 1068 浏览 1 评论 0原文

在顶点中，如果我想循环“内部”类的所有成员&根据它创建一个映射（成员名称到其值）。我该怎么做？

提前致谢。

public class fromJSON{

公共布尔成功；公共整数时间戳； //1646140623 公共字符串基础； //欧元公共字符串日期J； //2022-03-01 公共地图<字符串，十进制>费率；公共 cls_rates 费率；

 class cls_rates {
     public Double AED; 
     public Double AFN; 
     public Double ALL; 
     public Double AMD; 
     public Double ANG; 
     public Double AOA; 
     public Double ARS; 
     public Double AUD; 
     public Double AWG; 
     public Double AZN; 
     public Double BAM; 
     public Double BBD; 
     public Double BDT; 
     public Double BGN; 
     public Double BHD; 
     public Double BIF; 
     public Double BMD; 
     public Double BND; 
     public Double BOB; 
     public Double BRL; 
     public Double BSD; 
     public Double BTC; 
     public Double BTN; 
     public Double BWP; 
     public Double BYN; 
     public Double BYR; 
     public Double BZD; 
     public Double CAD; 
     public Double CDF; 
     public Double CHF; 
     public Double CLF; 
}

}

In apex, if I want to loop over all members of a "inner" class & create a map from it (member name to its value).
How do I do that?

Thanks in advance.

public class fromJSON{

public boolean success;
public Integer timestamp; //1646140623
public String base; //EUR
public String dateJ; //2022-03-01
public Map<String, Decimal> rates;
public cls_rates rates;

 class cls_rates {
     public Double AED; 
     public Double AFN; 
     public Double ALL; 
     public Double AMD; 
     public Double ANG; 
     public Double AOA; 
     public Double ARS; 
     public Double AUD; 
     public Double AWG; 
     public Double AZN; 
     public Double BAM; 
     public Double BBD; 
     public Double BDT; 
     public Double BGN; 
     public Double BHD; 
     public Double BIF; 
     public Double BMD; 
     public Double BND; 
     public Double BOB; 
     public Double BRL; 
     public Double BSD; 
     public Double BTC; 
     public Double BTN; 
     public Double BWP; 
     public Double BYN; 
     public Double BYR; 
     public Double BZD; 
     public Double CAD; 
     public Double CDF; 
     public Double CHF; 
     public Double CLF; 
}

}

我们可能需要序列化内部类对象，并且需要使用deserializeUntyped方法将其反序列化，以将内部类成员变量保存到映射中。

//Create a instance of the inner class
fromJSON.cls_rates rates=new fromJSON.cls_rates();

//Setting some variable for demo purpose
rates.AED = 10.0;

//Serializing the inner class instance to json string 
String jsonStr = JSON.serialize(rates);


//Deserializing the json string to a map with key and values from the inner class
Map<String, Object> jsonMap = (Map<String, Object>)JSON.deserializeUntyped(jsonStr);

System.debug('jsonMap : '+jsonMap);

We may need to serialize the inner class object and we would need to deserialize it using deserializeUntyped method for holding the inner class members variables into a map.

//Create a instance of the inner class
fromJSON.cls_rates rates=new fromJSON.cls_rates();

//Setting some variable for demo purpose
rates.AED = 10.0;

//Serializing the inner class instance to json string 
String jsonStr = JSON.serialize(rates);


//Deserializing the json string to a map with key and values from the inner class
Map<String, Object> jsonMap = (Map<String, Object>)JSON.deserializeUntyped(jsonStr);

System.debug('jsonMap : '+jsonMap);
