Class Logger

  com.jmobilecore.support.Logger

public class Logger
extends java.lang.Object

Logs messages to the system output stream.

All methods are wrapped in Debug.ON checks; If Debug.ON is false then all methods simply return doing nothing. However, for optimizaton purpose all calles should be wrapped into Debug.ON checks Example:

  if ( Debug.ON ) {
    Logger.development( "Some message" );
  }
 

or:

  if ( Debug.ON ) {
    Logger.OUTPUT_ON = false;
    System.err.println( Logger.development( "Some message" ) );
  }
