[英]OMNeT++ disassembling received messages
I want to read data from my received message in OMNeT++ and store it. 我想从收到的OMNeT ++消息中读取数据并将其存储。
This is what my message format looks like: 这是我的消息格式:
packet ServerMsg
{
String code;
String text;
}
I know how to build and send it, but not how to disassemble it at the receiving point. 我知道如何构建和发送它,但是不知道如何在接收点将其拆解。
Now I want to store 'code' in 'a' and 'text' in 'b'. 现在,我想将“代码”存储在“ a”中,将“文本”存储在“ b”中。
void Server::handleMessage(cMessage *msg) {
String a;
String b;
}
What's the way to go here? 去这里要走什么路?
You need to cast the incoming message to the appropriate type and then can access all the member variables of the message class: 您需要将传入的消息强制转换为适当的类型,然后可以访问消息类的所有成员变量:
#include "ServerMsg_m.h"
...
void Server::handleMessage(cMessage *msg) {
String a;
String b;
ServerMsg *pkt = check_and_cast<ServerMsg *>(msg);
a = pkt->a;
b = pkt->b;
}
