AWSLogger class

A logging utility providing the ability to emit log entries, configure the level at which entries are emitted, and register plugins which can handle log entries as they're emitted.

Plugins are created by implementing AWSLoggerPlugin and calling AWSLogger.registerPlugin on an AWSLogger instance.

By default, a SimpleLogPrinter is registered on the root AWSLogger which impacts all child loggers.

Constructors

AWSLogger([String namespace = rootNamespace]): Creates a top-level AWSLogger.
factory
AWSLogger.detached([String namespace = 'Detached']): Creates a detached AWSLogger which is not part of the global hierarchy.
AWSLogger.protected(String namespace): A logging utility providing the ability to emit log entries, configure the level at which entries are emitted, and register plugins which can handle log entries as they're emitted.
