public final class Logger:

Logger

Named producer of immutable log events.

Logger instances are cached by LogManager; acquiring a logger is cheap and the object may be retained in a class constant.

Example

import klyn.logging

logger = LogManager.getLogger("myapp")
logger.info("Server started", port = 8080)
