/** @defgroup AutoInitLog4cxx Automatically initialize log4cxx |
|
|
|
If you want to enable log4cxx |
|
(http://logging.apache.org/log4cxx), you have to configure it in |
|
your application, normally in the main. If you want to configure |
|
it automatically, without changing a single line in your code |
|
(e.g. for temporary debugging), simply link to @c |
|
libmrwlog4cxxconfiguration, either with option @c |
|
-lmrwlog4cxxconfiguration for single threaded, or with @c |
|
-lmrwlog4cxxconfiguration-mt for multi threaded applications. |
|
|
|
With @ref trclog4cxx and @ref |
|
AutoFunctionTrace, you can add tracing based on @c log4cxx, |
|
without even change a single line in your code. But your code |
|
still has to initialize @c log4cxx. If you even want to |
|
automatically initialize @c log4cxx, use this library! |
|
|
|
Configures @c log4cxx in the following way: |
|
-# if available, read @c log4cxx property file |
|
(read first file found, in this order) |
|
-# file specified in environment variable |
|
@c $MRW_LOG4CXX_CONFIGFILE |
|
-# <code>.mrwlog4cxx</code> (local file) |
|
-# <code>~/.mrwlog4cxx</code> (file in user's home) |
|
-# <code>/etc/mrwlog4cxx</code> (global configuration) |
|
-# if no configuration file is found, use default configuration: |
|
@verbatim |
|
log4j.rootLogger = DEBUG, A1 |
|
log4j.logger.mrw.fn = DEBUG, A1 |
|
log4j.logger.mrw.fn.log4cxx = OFF, A1 |
|
log4j.logger.mrw.fn.boost = OFF, A1 |
|
log4j.logger.mrw.fn.Thread = OFF, A1 |
|
log4j.logger.mrw.fn.QString = OFF, A1 |
|
log4j.logger.mrw.fn.QShared = OFF, A1 |
|
log4j.logger.mrw.fn.QWidget = OFF, A1 |
|
log4j.logger.mrw.fn.mrw = OFF, A1 |
|
log4j.logger.mrw.fn.std = OFF, A1 |
|
log4j.logger.mrw.fn.new = OFF, A1 |
|
log4j.logger.mrw.fn.CppUnit = OFF, A1 |
|
log4j.logger.mrw.fn.__gnu_cxx = OFF, A1 |
|
log4j.appender.A1 = org.apache.log4j.ConsoleAppender |
|
log4j.appender.A1.layout = org.apache.log4j.PatternLayout |
|
@endverbatim |
|
and for multi threaded programs in addition: |
|
@verbatim |
|
log4j.appender.A1.layout.ConversionPattern = t-%-60c%m%n |
|
@endverbatim |
|
on the other hand, single threaded programs are formatted as: |
|
@verbatim |
|
log4j.appender.A1.layout.ConversionPattern = 60c%m%n |
|
@endverbatim |
|
This results in the following behaviour: |
|
- trace to console |
|
- format as... |
|
- @c "%t-%-60c%m%n" if threaded |
|
- @c "%-60c%m%n" if not threaded |
|
- enable all tracing to @c DEBUG |
|
- enable tracing of @ref AutoFunctionTrace |
|
- disable function trace for @c log4cxx |
|
- disable function trace for @c boost |
|
- disable function trace for @c Qt base classes |
|
- disable function trace for @c libmrw |
|
- disable function trace for @c std and @c new |
|
- disable function trace for @c CppUnit |
|
- disable function trace for @c gcc internals |
