Examples of LogContext

com.sleepycat.je.log.LogContext
Context parameters that apply to all logged items when multiple items are logged in one log operation. Passed to LogManager log methods and to beforeLog and afterLog methods.
com.taobao.tddl.dbsync.binlog.LogContext
TODO: Document Me!! NOTE: Log context will NOT write multi-threaded. @author Changyuan.lh @version 1.0
javolution.context.LogContext
orarily disables logging. try { ClassInitializer.initializeAll(); // Initializes bootstrap, extensions and classpath classes. } finally { LogContext.exit(LogContext.NULL); // Goes back to default logging. } ... }[/code]

Applications may extend this base class to address specific logging requirements. For example:[code] // This class allows for custom logging of session events. public abstract class SessionLog extends LogContext { public static void start(Session session) { LogContext log = LogContext.current(); if (log instanceof SessionLog.Loggable) { ((SessionLog.Loggable)log).logStart(session); } else if (log.infoLogged()){ log.logInfo("Session " + session.id() + " started"); } } public static void end(Session session) { ... } public interface Loggable { void logStart(Session session); void logEnd(Session session); } }[/code]

The use of interfaces (such as Loggable above) makes it easy for any context to support customs logging events. For example:[code] class MyLog extends StandardLog implements SessionLog.Loggable, DatabaseLog.Loggable { ... // Specialized logging for session and database events. } MyLog myLog = new MyLog(); LogContext.enter(myLog); try { ... LogContext.info("Informative message"); // Standard logging. ... DatabaseLog.fail(transaction); // Database custom logging. ... SessionLog.start(session); // Session custom logging. ... } finally { LogContext.exit(myLog); }[/code]

org.grouplens.lenskit.util.LogContext
Utility class to manage log data with {@link MDC}. This class allows MDC parameters to be set, and popped back off when the context is finished.
org.jboss.logmanager.LogContext
A logging context, for producing isolated logging environments.
