Package org.geotools.util.logging
Class CommonsLoggerFactory
Object
LoggerFactory<Log>
CommonsLoggerFactory
A factory for loggers that redirect all Java logging events to the Apache's Commons-logging framework.
Out of the box commons logging delegates to the java util logging framework (using the class
org.apache.commons.logging.impl.Jdk14Logger). If this factory detects Commons logging is already delegating to
Jdk14Logger it will return null
allowing java util logging directly.
