Package org.slf4j.log4j12

Class Log4jLoggerAdapter

java.lang.Object

org.slf4j.helpers.AbstractLogger

org.slf4j.helpers.LegacyAbstractLogger

org.slf4j.log4j12.Log4jLoggerAdapter

All Implemented Interfaces:

Serializable, Logger, LocationAwareLogger, LoggingEventAware

public final class Log4jLoggerAdapter
extends LegacyAbstractLogger
implements LocationAwareLogger, LoggingEventAware, Serializable

A wrapper over org.apache.log4j.Logger in conforming to the Logger interface.

Note that the logging levels mentioned in this class refer to those defined in the org.apache.log4j.Level class.

The TRACE level was introduced in log4j version 1.2.12. In order to avoid crashing the host application, in the case the log4j version in use predates 1.2.12, the TRACE level will be mapped as DEBUG. See also SLF4J-59.
