org.jzonic.jlo.CommonsLogManager

CommonsLogManager
public class CommonsLogManager extends LogFactory implements FileListener(Code)
This class manages all LogConfigurations. It is the point of entry for jLo. There is only one instance of the LogManager to make sure that all classes in one JVM will work with the same configurations.
In order to get a Logger you have to call:
 private static final Logger logger = LogManager.getLogger("com.foo.app");
 
In this case the LogManager when instanciated will search for a file called "jlo_logging.xml" in your classpath and process it.
This method is error save that means that it will always return a valid Logger.
Since jLo supports many LogConfigurations you can also use this method:
 private static final Logger logger = LogManager.getLogger("com.foo.app","foo");
 
If you provide a configuration name then the LogManager will search for a file called "foo_logging.xml" in your classpath and process it.

Constructor Detail
CommonsLogManager
public CommonsLogManager()(Code)




Method Detail
fileChanged
public void fileChanged(FileListenerEvent e)(Code)
This method, once implemented, will be called when the File object itself changes.
Parameters:
  FileListenerEvent - The FileListener object.



flush
public void flush()(Code)
Call thi smethod if you want to force the LogProcessor to write all pending log statements immediately



getAttribute
public Object getAttribute(String arg0)(Code)



getAttributeNames
public String[] getAttributeNames()(Code)



getInstance
public static CommonsLogManager getInstance()(Code)
This method returns the one and only instance of the LogManager. the instance of the LogManager



getInstance
public Log getInstance(String str) throws org.apache.commons.logging.LogConfigurationException(Code)



getInstance
public Log getInstance(Class clazz) throws org.apache.commons.logging.LogConfigurationException(Code)



getLog
public static Log getLog(String loggerName)(Code)
This method returns a Logger from the LogConfiguration. The name of the LogConfiguration is default and the corresponding file is jlo_logging.xml. This method uses the LogConfiguration.getLogger method.
Parameters:
  loggerName - the name of the logger the Logger or the DefaultLogger if not found



getLog
public static Log getLog(String loggerName, String configurationName)(Code)
This methods returns a logger for the given name from the specific logconfiguration. If a logger with the given name does not exist then the LogConfiguration will try to search for it by going up the hierarchy. If still no logger is found then this method will return the DefaultLogger. This method will never return null therefore it is save to do this:
 private static final Logger logger = LogManager.getLogger("org.foo.app");
 
in your class. If there is no instance of the LogManager so far then a new one will be created.
Parameters:
  loggerName - the name of the logger
Parameters:
  configurationName - the name of the configuration the requested logger or the next one in the hierarchy or the default
