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.
