Class Logger

java.lang.Object

org.bushe.swing.event.Logger

public class Logger
extends Object

Central Logging class. Shields code from Logging implementation.

The EventBus allows operation in two modes - using java.util.logging so that the EventBus can be deployed in its own jar or using any logging system supported by apache commons logging, which of course requires other jars.

The EventBus logging uses the names of its classes as the log, primarily "org.bushe.swing.event.EventService". This aids in debugging which subscription and publication issues.

Implementation note: There are no imports in this class to make things explicit. There is also no explicit use of classes outside java.util, anything else is used by reflection to avoid NoClassDefFound errors on class load.
