Examples of TopicalLogger

org.objectweb.util.monolog.api.TopicalLogger

A TopicalLogger dispatches events to a set of Handlers. A TopicalLogger is a sort of message router.

A topic is associated with each TopicalLogger. A topic is represented by a dotted string, which is used to build a hierarchical namespace. The latter should typically be aligned with the Java packaging namespace.

The name hierarchy of TopicalLogger allows adding properties inheritance. For example, a TopicalLogger with the "a.b.c" name can inherit of the Handlers list and the level from the "a.b" parent.

Another property for a TopicalLogger is the capacity to have several topics. This is important when a component is used by several other components. This will allow events logged by the shared component to appear for each component using this shared component. A consequence of this property is that a Logger may have several parents

The additivity flag indicates if the current TopicalLogger inherits the handlers of its parents. The default value is true.
