Relations Between Category and Location

Use

It is common practice to look at the log and trace messages together when you perform a diagnosis. A correlation between a problematic area and the source code location that generates the problem is highly desired.

Example

This example only shows the attachment of a location to a category but this is relevant for the opposite case, too.

package com.sap.fooPackage;
 
import com.sap.tc.logging.*;
 
public class Node {
   private static final Location loc =
      Location.getLocation("com.sap.fooPackage.Node");
   private static final Category objMgmt =
      Category.getCategory("/Objects/Management");
   public void announce(Object o) {
      final String method = "announce(java.lang.Object)";
      loc.entering(method, new Object[] { o });
      try {
         // Register object ...
      }
      catch
 (RegistrationException e) {
           objMgmt.errorT(loc, method, "Error registering new object {0}.", 
 Object[] {o});
      }
      loc.exiting();
   }  // method announce
}  // class Node
