Interface RuntimeLogger

All Superinterfaces:

LogPriorityAccessor, MessageLogger<LogPriority>, org.refcodes.mixin.NameAccessor

All Known Implementing Classes:

RuntimeLoggerImpl, RuntimeLoggerSingleton

public interface RuntimeLogger
extends MessageLogger<LogPriority>, LogPriorityAccessor, org.refcodes.mixin.NameAccessor

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:

• SystemLoggerImpl
• AsyncLoggerImpl
• ConsoleLoggerImpl (ConsoleLoggerImpl)
• IoLoggerImpl
• SimpleDbLoggerImpl
• SimpleDbLoggerImpl
• Slf4jLoggerImpl

(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 "runtimelogger-config.xml" file (using apache configurations notation).

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 Detail

log

void log(LogPriority aPriority,
         String aMessage,
         Throwable aThrowable)

Creates a new log message.

Parameters:

aPriority - The level of the message.

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.
