Parameters in a fonction

Question

Hi all,
I have a problem, I need to know the name and the value of the parameters I'm using in a method, by example:
void method1 (int a, int b, int c)
// in this part I need to know dinamycally that I have (int a, int b, int c) as parameters
The point is that I need to send those names and values to a file, but the method can be changed to:
void method1 (int a, int b, int c, int d)
// in this part I need to know dinamycally that I have (int a, int b, int c, int d ) as parameters
Any idea
Merci!!!

// in this part I need to know dinamycally that I have
(int a, int b, int c, int d ) as parametersI think I vaguely understand what you're getting at, but no, there's no way of knowing this. There's certainly no way of knowing the names of the parameters.
The types, maybe - you can create a new local Exception, and get its stack trace, and look at element 0 for the method name, and parse it.
So you'll have to resort to some sort of programmer-maintained information at the start of each such method.
For instance, in one of my APIs, I wanted to log each call and its parameters. So I created a "logging" class that is passed a method name, and gets an appropriate Logger for it, and then a "logEntry()" and "logExit()" method to log the entry and exit. The way I call it is as follows:
  public boolean login(String applicationName, String userName, String password)
    // throws ...
      CommonAPI.LogInfo logInfo = CommonAPI.apiLogger("App", "login");  // the method is App.login()
      if (logInfo != null) {
        logInfo.logEntry(new String[]{"applicationName","userName","password"},
                         new Object[]{applicationName,userName,"********"});
  }Notice how I pass this logging routine an array of parameter names, and an array of parameter values.
You can adopt a similar idiom in your code..
