| Name | Package | Description |
| AvalonLogger | org.apache.commons.logging.impl | Implementation of commons-logging Log interface that delegates all
logging calls to the Avalon logging abstraction: the Logger interface. |
| Jdk13LumberjackLogger | org.apache.commons.logging.impl | 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 | org.apache.commons.logging.impl | 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). |
| Log4JLogger | org.apache.commons.logging.impl | Implementation of Log that maps directly to a
Logger for log4J version 1.2. |
| LogFactory | org.apache.commons.logging | Factory for creating Log instances, with discovery and
configuration features similar to that employed by standard Java APIs
such as JAXP. |
| LogFactoryImpl | org.apache.commons.logging.impl | Concrete subclass of LogFactory that implements the
following algorithm to dynamically select a logging implementation
class to instantiate a wrapper for. |
| LogKitLogger | org.apache.commons.logging.impl | Implementation of org.apache.commons.logging.Log
that wraps the avalon-logkit
logging system. |
| LogSource | org.apache.commons.logging | Factory for creating Log instances. |
| NoOpLog | org.apache.commons.logging.impl | Trivial implementation of Log that throws away all messages. |
| ServletContextCleaner | org.apache.commons.logging.impl | 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 | org.apache.commons.logging.impl | Simple implementation of Log that sends all enabled log messages,
for all defined loggers, to System.err. |
| WeakHashtable | org.apache.commons.logging.impl | Implementation of Hashtable that uses WeakReference's
to hold its keys thus allowing them to be reclaimed by the garbage collector. |
