How do I know which Thread called my Log method?

Question

I have a Log class that has several static methods which help log information about my program.

My problem is that I have 2 threads running and both of them send requests to my Log class to log information.

I would like to have my Log class show which threads are logging which lines.

What should I do to achieve this functionality?

My code is basically like this:

 public class Log {
     public static void log ( String tag , Object message ) 
     {
         String lineToPrint = "";
         //Builds the string taking in time data and other information
         //...
         //This is where I want to see which thread called this log function
         //...

         System.out.println( lineToPrint );
     }
 }

Answer 1

Add this to your logger:

Thread t = Thread.currentThread();
String name = t.getName();

and dump it to log file.

Answer 2

public class Temp{
   static Thread t = null;
}

temp.t = Thread.currentThread();

 public static void log ( String tag , Object message ) 
 {
         temp.t.getName();//get it
 }

Also, with respect to pthread s, the function for knowing about the calling thread is: pthread_t pthread_self (void);
