Package nl.vpro.logging.simple

Available logging frameworks are sometimes a bit hard. The de facto standard at vpro is slf4j. Its interface is however hard to completely implement. SimpleLogger is much easier. A complete implementation may be just a few lines. Performance is not a key goal of this framework. The main goal is easy of implementation. The basic idea is that a logger is not much more then a consumer of messages. These could be written to some logger framework, but sometimes you want to do something else with it too. E.g. collecting it in JMX calls, or throwing it on web sockets so that web site users can see them too. A SimpleLogger therefor is a good choice if methods use some Logger as an argument. The method is somewhat restricted, but the caller can decide what to do with logging very easily.

Class Summary

Class	Description
AbstractStringBuilderSimpleLogger	Simply logs everything to a StringBuilder.
ChainedSimpleLogger	Wraps all log events to zero or more other instances of SimpleLogger
ConsoleLogger	Simply logs everything to stdout/stderr
Event	A representation of a log event
Event.Builder
EventSimpleLogger<E extends Event>	A SimpleLogger wraps a consumer for every log Event's (or possibly extensions thereof) It is abstract because you need to implement how to instantiate a new Event extension via EventSimpleLogger.createEvent(Level, CharSequence, Throwable) If you have no need for that, you can instantiate via EventSimpleLogger.of(Consumer), or use EventSimpleLogger.createEvent(Level, CharSequence, Throwable, Clock)
FileSimpleLogger	Simply logs everything to a File.
FileSimpleLogger.Builder
FloggerSimpleLogger
JULSimpleLogger	SimpleLogger that wraps a java.util.logger.
Log4j2SimpleLogger	SimpleLogger that wraps log4j2's Logger.
NOPLogger
OutputStreamSimpleLogger	A SimpleLogger implementation that just writes everything to a OutputStream
OutputStreamSimpleLogger.Builder
QueueSimpleLogger<E extends Event>	A SimpleLogger that adds every log event to a Queue of QueueSimpleLogger.Event's (or possibly extensions thereof)
QueueSimpleLogger.Event	Deprecated. Just use Event
QueueSimpleLogger.Event.Builder
SimpleLogger.RemoveFromThreadLocal
SimpleLoggerOutputStream	If you want to convert a SimpleLogger to a OutputStream this can be used.
SimpleLoggerWrapper	It is hard to wrap every call to e.g.
Slf4jSimpleLogger	Wraps an SLF4J Logger
StringBuilderSimpleLogger	Simply logs everything to a StringBuilder.
StringBuilderSimpleLogger.Builder
StringSupplierChainedSimpleLogger
