Module org.apache.logging.log4j

Log4j public API for libraries and applications. This module is provided as a portable logging API which supports independent logging provider backends for configuring the underlying logging system. The org.apache.logging.log4j package contains the main APIs for loggers, markers, logging levels, thread context maps (aka MDC), and thread context stacks (aka NDC).

Logging provider SPIs are located in org.apache.logging.log4j.spi. A reference implementation is given in org.apache.logging.log4j.simple which is used internally by the status logger API.
