Method Detail

beforeInitialize

public void beforeInitialize()

Description copied from class: LoggingSystem

Reset the logging system to be limit output. This method may be called before LoggingSystem.initialize(String, LogFile) to reduce logging noise until the system has been fully Initialized.

Specified by:

beforeInitialize in class LoggingSystem

initialize

public void initialize(String configLocation,
              LogFile logFile)

Description copied from class: LoggingSystem

Fully initialize the logging system.

Specified by:

initialize in class LoggingSystem

Parameters:

configLocation - a log configuration location or null if default initialization is required

logFile - the log output file that should be written or null for console only output

getSelfInitializationConfig

protected String getSelfInitializationConfig()

Return any self initialization config that has been applied. By default this method checks getStandardConfigLocations() and assumes that any file that exists will have been applied.

Returns:

the self initialization config

getStandardConfigLocations

protected abstract String[] getStandardConfigLocations()

Return the standard config locations for this system.

Returns:

the standard config locations

See Also:

getSelfInitializationConfig()

loadDefaults

protected abstract void loadDefaults(LogFile logFile)

Load sensible defaults for the logging system.

Parameters:

logFile - the file to load or null if no log file is to be written

loadConfiguration

protected abstract void loadConfiguration(String location,
                     LogFile logFile)

Load a specific configuration.

Parameters:

location - the location of the configuration to load (never null)

logFile - the file to load or null if no log file is to be written

reinitialize

protected void reinitialize()

Reinitialize the logging system if required. Called when getSelfInitializationConfig() is used and the log file hasn't changed. May be used to reload configuration (for example to pickup additional System properties).

getClassLoader

protected final ClassLoader getClassLoader()

getPackagedConfigFile

protected final String getPackagedConfigFile(String fileName)
