TraitLog

Methods / Usages

Attachs a configurable console logger to the component, using JFactoryLogger.

• The logs are automatically labeled with the value of myComponent.$.about.name
• The logger can be enabled or disabled at runtime.

Although it is not directly supported by TraitLog, a JFactoryLogger can also:

• Create children that can be disabled by inheritance.
• Filter by label and methods (log, warn, error).

Inherited config

By default, for all components, logs are :

• disabled when using the production distribution of jFactory.
• enabled when using the development distribution of jFactory.

[//]: # (TODO This behavior can be changed by setting jFactoryConfig.TraitLog.enabled = true

false)

Component config

• myComponent.$.logger.enable()
• myComponent.$.logger.disable()
