SimpleLogger Class

Use

This new class is easier to use than the methods in Category and Location .

It contains less output methods, providing enough functionality for your logging/tracing tasks.

SimpleLogger Method	Parameters	Description
`public static boolean isWritable`	(int severity, LogController lc)	Determines if a message with provided severity passes Log Controller's severity check. If so, the message is written.
`public static LogRecord log`	(int severity, Category category, Location location, String message, String messageID)	Logs message with specified severity and emits it to the Location parameter.
`public static LogRecord log`	(int severity, Category category, Location location, String message, String messageID, Object[] args)	Logs message with specified severity and emits it to the Location parameter. Replaces argument values directly in the log message
`public static LogRecord trace`	(int severity, Location location, String message)	Traces a message with specified severity.
`public static LogRecord trace`	(int severity, Location location, String message, String messageID)	Traces a message with specified severity.
`public static LogRecord trace`	(int severity, Location location, String message, St ring messageID, Object[] args)	Traces a message with specified severity. Replaces argument values directly in the trace message.
`public static LogRecord traceThrowable`	(int severity, Location location, String message, String messageID, Object[] args, Throwable exc)	Traces exception and its stack trace with the specified severity.
`public static LogRecord traceThrowable`	(int severity, Location location, String message, String messageID, Throwable exc)	Traces exception and its stack trace with the specified severity.
`public static LogRecord traceThrowable`	(int severity, Location location, String message, Throwable exc)	Traces exception and its stack trace with the specified severity.

Example


package com.sap.fooPackage;
import com.sap.tc.logging.*;
public class Node {
  private Object row[];
       //using the obsolete methods in "Category" and "Location"
  
private static finalLocation loc =
    Location.getLocation("com.sap.fooPackage.Node");
  private static final Category cat = 
    Category.getCategory(Category.SYS_DATABASE, "Node");
  public void announce(Object o) {
    String method = "announce(java.lang.Object)";
       // Perform a task, e.g. connecting to DB.
    try {
      // It won't be logged, since severity DEBUG is lower than WARNING.
      // using the SimpleLogger class  
      SimpleLogger.trace(Severity.DEBUG, loc, 
                                 method + " - " + "Connecting to ...");
      //minor error when writing something
      SimpleLogger.trace(Severity.WARNING, loc, 
                                 "Problems in row {0} to {1}",
                                                       row[0], row[1]);
      //error in the connection
      SimpleLogger.log(Severity.ERROR, cat, loc, "ASJ.dbn.000023", 
                                              "DB connection failure");
    } catch (Exception e) {
       SimpleLogger.log(Severity.ERROR, cat, loc, "ASJ.dbn.000024", 
                        "Error storing node {0} in database.", row[0]);
      }
  }  // method announced
}  // class NodeEnd of the code.
