Package org.apache.sis.util.logging
package org.apache.sis.util.logging
Extensions to the JDK logging framework.
This package provides:
- A
Logging
utility class with static methods for fetching a logger (see Choosing a logging framework below) or logging an exception. - A
PerformanceLevel
with configurable levels for logging the duration of lengthly processes. - A
MonolineFormatter
for formatting the log records on single line with colors, for easier reading on the console output.
Choosing a logging framework
The SIS project uses the standardLogger
API for its logging,
but this package allows redirection of logging messages to some other frameworks like
Log4J.
We recommend to stick to standard JDK logging when possible. However if inter-operability
with an other logging framework is required, then the only action needed is to include
one of the following JAR on the classpath:
sis-logging-commons.jar
for Apache loggingsis-logging-log4j.jar
for Log4J logging- Any other JAR registering a
LoggerFactory
implementation.
Note for SIS developers
All SIS code should fetch their logger through a call to our customLogging.getLogger(String)
method instead of
the standard Logger.getLogger(String)
method. This is necessary in
order to give SIS a chance to redirect log events to an other logging framework.- Since:
