@ProviderType public interface LoggerAdminLoggerAdmin service for configuring loggers.
Each bundle may have its own named
LoggerContextbased upon its bundle symbolic name, bundle version, and bundle location. There is also a root Logger Context from which each named Logger Context inherits. The root Logger Context has no name.
When a bundle logs, the logger implementation must locate the Logger Context for the bundle to determine the
effective log levelof the logger name. The best matching name for the Logger Context is the longest name, which has a non-empty Logger Context, according to this syntax:
name ::= symbolic-name ( '|' version ( '|' location )? )?The version must be formatted canonically, that is, according to the
toString()method of the
Versionclass. So the Logger Context for a bundle is searched for using the following names in the given order:
<symbolic-name>|<version>|<location> <symbolic-name>|<version> <symbolic-name>The search stops at the first
non-emptyLogger Context. If no non-empty Logger Context is found using the above search order, the Logger Context with the symbolic name of the bundle must be used for the bundle.
