All Classes

Class Summary
AvalonLogger	Implementation of commons-logging Log interface that delegates all logging calls to the Avalon logging abstraction: the Logger interface.
Jdk13LumberjackLogger	Implementation of the `org.apache.commons.logging.Log` interface that wraps the standard JDK logging mechanisms that are available in SourceForge's Lumberjack for JDKs prior to 1.4.
Jdk14Logger	Implementation of the `org.apache.commons.logging.Log` interface that wraps the standard JDK logging mechanisms that were introduced in the Merlin release (JDK 1.4).
Log	A simple logging interface abstracting logging APIs.
Log4JLogger	Implementation of Log that maps directly to a Logger for log4J version 1.2.
LogConfigurationException	An exception that is thrown only if a suitable `LogFactory` or `Log` instance cannot be created by the corresponding factory methods.
LogFactory	Factory for creating Log instances, with discovery and configuration features similar to that employed by standard Java APIs such as JAXP. IMPLEMENTATION NOTE - This implementation is heavily based on the SAXParserFactory and DocumentBuilderFactory implementations (corresponding to the JAXP pluggability APIs) found in Apache Xerces.
LogFactoryImpl	Concrete subclass of LogFactory that implements the following algorithm to dynamically select a logging implementation class to instantiate a wrapper for. Use a factory configuration attribute named `org.apache.commons.logging.Log` to identify the requested implementation class. Use the `org.apache.commons.logging.Log` system property to identify the requested implementation class. If Log4J is available, return an instance of `org.apache.commons.logging.impl.Log4JLogger`. If JDK 1.4 or later is available, return an instance of `org.apache.commons.logging.impl.Jdk14Logger`. Otherwise, return an instance of `org.apache.commons.logging.impl.SimpleLog`. If the selected Log implementation class has a `setLogFactory()` method that accepts a LogFactory parameter, this method will be called on each newly created instance to identify the associated factory.
LogKitLogger	Implementation of `org.apache.commons.logging.Log` that wraps the avalon-logkit logging system.
LogSource	Factory for creating Log instances.
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 of `Hashtable` that uses `WeakReference`'s to hold its keys thus allowing them to be reclaimed by the garbage collector.
WeakHashtable.Entry	Entry implementation
WeakHashtable.Referenced	Wrapper giving correct symantics for equals and hashcode
WeakHashtable.WeakKey	WeakReference subclass that holds a hard reference to an associated `value` and also makes accessible the Referenced object holding it.
