Defined in:

lib/lumberjack/device/null.rb

Overview

A logging device that discards all output. This device provides a silent logging implementation useful for testing environments, performance benchmarks, or production scenarios where logging needs to be temporarily disabled without changing logger configuration.

The Null device implements the complete Device interface but performs no actual operations, making it both efficient and transparent. It accepts any constructor arguments for compatibility but ignores them all.

Examples:

Creating a silent logger

logger = Lumberjack::Logger.new(Lumberjack::Device::Null.new)
logger.info("This message is discarded")

Using the convenience constructor

logger = Lumberjack::Logger.new(:null)
logger.error("This error is also discarded")
