Package org.javasimon.callback.logging

LoggingCallback is able to log stopwatch splits and statistics once in a while (N per millisecond, every N split, when split is longer than N ms, etc.)

LogMessageSource<C>

Message provider, converts context into a loggable string.

Class Summary

CounterLogTemplate<C>	Log template that logs something every N invocations of the CounterLogTemplate.isEnabled(Object) method.

LogTemplate<C>	Log template interface is the root of a hierarchy of implementations with different purposes.
LogTemplates	Factory of LogTemplates.
PeriodicLogTemplate<C>	Log template that logs something after every N milliseconds.
SLF4JLogTemplate<C>	Concrete log template using SLF4J Logger.
SLF4JLogTemplate.Debug<C>	SLF4J Log template with DEBUG level.
SLF4JLogTemplate.Info<C>	SLF4J Log template with INFO level.

Package org.javasimon.callback.logging Description

LoggingCallback is able to log stopwatch splits and statistics once in a while (N per millisecond, every N split, when split is longer than N ms, etc.) and to various outputs (SLF4J, JUL). These logging strategies are called log templates inherit from LogTemplate and are produced by LogTemplates (factory class):

• SLF4JLogTemplate: where → in SLF4J Logger
• JULLogTemplate: where → in JUL Logger
• DisabledLogTemplate: where → in /dev/null
• DelegateLogTemplate: abstract log template delegating to a concrete log template
  • PeriodicLogTemplate: when → every N milliseconds
  • CounterLogTemplate: when → every N splits
  • SplitThresholdLogTemplate: when → splits lasts longer than N milliseconds

Then LogMessageSource is called back by the LogTemplate to get the message (a String) to log: what.
