Class AgentLogger

java.lang.Object

cz.cuni.amis.pogamut.base.utils.logging.AbstractAgentLogger

cz.cuni.amis.pogamut.base.utils.logging.AgentLogger

All Implemented Interfaces:

IJMXEnabled, IAgentLogger, IJMXAgentLogger

public class AgentLogger
extends AbstractAgentLogger

All logging apis are fine ... but we don't want to have loggers for classes but for instances - therefore we've created our wrapper allowing you to do two things quickly:

1. log things
2. create new logger categories

1) that's obvious - it should be easy

2) this may prove crucial for your debugging to have own logger for planner and another for emotions of your agents, etc.

Simply - every Agent instance (starting with the first abstract class AbstractAgent) has instance of this class (which is java.logging.Logger(s) wrapper).

Every agent's component has own LogCategory and you may obtain your own via getCategory() method.

LogCategory serves as a gateway for your log messages, it contains methods as you know them from java.logging API (things like fine(), info(), severe(), log(Level, msg), etc.).

Plus it allows you to obtain new LogHandler instances for that category (if you need to publish log messages from that category somewhere else).

Every LogHandler serves for filtering messages for one category and publishing them into one end (console, file, memory, whatever...).

Additionally every LogCategory has AgentLogger as its parent.
