public final class Generate extends java.lang.Object
Generates source code for custom or extended logger wrappers.Usage:
To generate source code for an extended logger that adds custom log levels to the existing ones:
java org.apache.logging.log4j.core.tools.Generate$ExtendedLogger <logger.class.name> <CUSTOMLEVEL>=<WEIGHT> [CUSTOMLEVEL2=WEIGHT2 [CUSTOMLEVEL3=WEIGHT3] ...]
Example of creating an extended logger:
java org.apache.logging.log4j.core.tools.Generate$ExtendedLogger com.mycomp.ExtLogger DIAG=350 NOTICE=450 VERBOSE=550
To generate source code for a custom logger that replaces the existing log levels with custom ones:
java org.apache.logging.log4j.core.tools.Generate$CustomLogger <logger.class.name> <CUSTOMLEVEL>=<WEIGHT> [CUSTOMLEVEL2=WEIGHT2 [CUSTOMLEVEL3=WEIGHT3] ...]
Example of creating a custom logger:
java org.apache.logging.log4j.core.tools.Generate$CustomLogger com.mycomp.MyLogger DEFCON1=350 DEFCON2=450 DEFCON3=550
