Class Summary Class Description AvalonLogger Implementation of commons-logging Log interface that delegates all logging calls to the Avalon logging abstraction: the Logger interface.Jdk13LumberjackLogger Implementation of theorg.apache.commons.logging.Loginterface that wraps the standard JDK logging mechanisms that are available in SourceForge's Lumberjack for JDKs prior to 1.4.Jdk14Logger Implementation of theorg.apache.commons.logging.Loginterface that wraps the standard JDK logging mechanisms that were introduced in the Merlin release (JDK 1.4).Log4JLogger Implementation ofLogthat maps directly to a Logger for log4J version 1.2.LogFactoryImpl Concrete subclass ofLogFactorythat implements the following algorithm to dynamically select a logging implementation class to instantiate a wrapper for: Use a factory configuration attribute namedorg.apache.commons.logging.Logto identify the requested implementation class. Use theorg.apache.commons.logging.Logsystem property to identify the requested implementation class. If Log4J is available, return an instance oforg.apache.commons.logging.impl.Log4JLogger. If JDK 1.4 or later is available, return an instance oforg.apache.commons.logging.impl.Jdk14Logger. Otherwise, return an instance oforg.apache.commons.logging.impl.SimpleLog.LogKitLogger Implementation oforg.apache.commons.logging.Logthat wraps the avalon-logkit logging system.NoOpLog Trivial implementation of Log that throws away all messages.ServletContextCleaner This class is capable of receiving notifications about the undeployment of a webapp, and responds by ensuring that commons-logging releases all memory associated with the undeployed webapp.SimpleLog Simple implementation of Log that sends all enabled log messages, for all defined loggers, to System.err.WeakHashtable Implementation ofHashtablethat usesWeakReference's to hold its keys thus allowing them to be reclaimed by the garbage collector.WeakHashtable.Entry Entry implementationWeakHashtable.Referenced Wrapper giving correct symantics for equals and hashcodeWeakHashtable.WeakKey WeakReference subclass that holds a hard reference to an associatedvalueand also makes accessible the Referenced object holding it.
