getConfiguration

public Configuration getConfiguration()
                               throws java.lang.Exception

The current configuration. For best performance, this method should return the same Configuration repeatedly, switching to a new Configuration only when necessary (e.g. when the old configuration is intolerably stale). Callers of this method do less work when this method returns the same object repeatedly.
