Class LogFile

  wt.util.LogFile

public class LogFile

extends Object

A convenience class for redirecting system output and error streams to a log file. It uses the LogOutputStream class to add log information to these streams.

This should only be used in an application main method. The System.out and System.err streams are static finals. Optimizing JIT compilers are allowed to perform optimzations on such variables that will produce possibly fatal runtime errors if they are changed later.

init

public static void init(String name,
                        boolean append,
                        boolean tee)
                 throws IOException

Creates a log file with the specified system dependent file name. The standard system output and error streams are redirected to this log file. Parent directories are automatically created if they do not exist.

This should only be used in an application main method. The System.out and System.err streams are static finals. Optimizing JIT compilers are allowed to perform optimzations on such variables that will produce possibly fatal runtime errors if they are changed later.

Parameters:

name - the system dependent file name

append - open file in append mode?

tee - tee output to both log file and current standard streams

Throws:

IOException - If the file cannot be opened.
