Interface RuntimeLogger

All Superinterfaces:
LogDecorator, LogPriorityAccessor, MessageLogger<LogPriority>, org.refcodes.mixin.NameAccessor
All Known Implementing Classes:
RuntimeLoggerImpl, RuntimeLoggerSingleton
public interface RuntimeLogger extends MessageLogger<LogPriority>, LogPriorityAccessor, org.refcodes.mixin.NameAccessor, LogDecorator
Plain simple interface for logging out runtime information generated by software systems. The RuntimeLogger defines a plain simple interface for logging out runtime information generated by software systems. The RuntimeLoggerImpl implementation takes care of logging out the class and the method generating a log line. The RuntimeLoggerImpl actually takes a Logger instance; which implementation to take is up to you:
  • SystemLogger
  • AsyncLogger
  • ConsoleLogger (ConsoleLogger)
  • IoLogger
  • SimpleDbLoggerImpl
  • SimpleDbLoggerImpl
  • Slf4jLogger
(you find the various Logger implementations in the refcodes-logger-alt artifact's modules) Use the factory (the factory is implemented as a singleton) RuntimeLoggerFactorySingleton retrieving RuntimeLogger instances configured by a "runtimelogge.ini" file using the RuntimeProperties as well as the PolyglotProperties. This means you can use YAML, TOML, INI, PROPERTIES, XML or JSON notations. A SLF4J binding exists in the refcodes-logger-ext-slf4j" artifact which binds the refcodes-logger framework to SLF4J enabling to log all your SLF4J logs out by the refcodes-logger framework, e.g. to a SimpleDbLoggerImpl. The RuntimeLogger may also be configured with one of the below mentioned loggers.

  • Method Details

    • log

      void log(LogPriority aPriority, String aMessage, Throwable aThrowable)
      Creates a new log message.
      Parameters:
      aPriority - The level of the message.
      aMessage - The message to be logged.
      aThrowable - An exception that the message should contain.

    • log

      void log(LogPriority aPriority, String aMessage, Throwable aThrowable, Object... aArguments)
      Creates a new log message. The placeholders in the message String are being replaced by the provided arguments. Implementations of this interface are recommended to use Java's MessageFormat's syntax, the placeholder being replaced by the first argument is identified by "{0}" (without the quotes), the second one by "{1}", the third one by "{3}" and so on: Given the message to be "{0} + {1} = {2}" and the three argument be x, y and x + y, then "{0}" is replaced by the value of x, "{1}" is replaced by the value of y and "{2}" is replaced by the value of x + y.
      Parameters:
      aPriority - The level of the message.
      aMessage - The message to be logged.
