Logger Interface

public interface Logger

The Logger interface defines application logging functions. A Logger can be obtained from a JwsContext or ControlContext instance. Logging may be enabled at one of four levels: "debug" (lowest level, results in highest volume of output), "info", "warn" or "error" (highest level, results in least output). Messages emitted below the current logging level are not logged.
