## com.bea.commerce.ebusiness.discount.util
Class Log

    java.lang.Object
      com.bea.commerce.ebusiness.discount.util.Log

public class Log
extends Object

This class provides some very simple logging interfaces. Everything is static, so just call `Log.info()`, etc. All static methods for this Singleton service.

Field Summary
`static boolean` | `consoleMode` flag for logging to console in addition to log file
`static String` | `logDir` Directory holding log output
`static String` | `logFile` The name of the file holding log output
`static PrintWriter` | `logWriter` output for stderr console logging
`static PrintWriter` | `stderrWriter` output for stderr console logging
`static PrintWriter` | `stdoutWriter` output for stdout console logging
`static String` | `T_SEP`

Constructor Summary
`Log()`
