Class IndependantLog

java.lang.Object

org.safs.IndependantLog

public class IndependantLog
extends java.lang.Object

Use reflection for org.safs.Log to do the Log work. By this way, we don't need to import org.safs.Log which will depend on STAF. In some environments, there is no STAF Library. If we import org.safs.Log, there is a compilation error or ClassNotFoundException.

For example, on Android device, we don't have STAF library. But our Droid-Engine needs some classes extending the existing SAFS class who uses org.safs.Log We can replace Log.XXX() by IndependantLog.XXX() in the SAFS class.
