Direct Known Subclasses:

ExtLogManager

public class ScrLogManager
extends LogManager

Implements a SCR based log manager. This class was needed to not change the whole codebase. It looks very similar to the old logging but leverages the LogManager. This class implements the existing behavior and the ExtLogManager implements the extension behavior. The scr() method makes this distinction based on the configuration.
