Method Detail

getStandardConfigLocations

protected String[] getStandardConfigLocations()

Description copied from class: AbstractLoggingSystem

Return the standard config locations for this system.

Specified by:

getStandardConfigLocations in class AbstractLoggingSystem

Returns:

the standard config locations

AbstractLoggingSystem.getSelfInitializationConfig()

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(LoggingInitializationContext, String, LogFile) to reduce logging noise until the system has been fully initialized.

Overrides:

beforeInitialize in class AbstractLoggingSystem

loadDefaults

protected void loadDefaults(LoggingInitializationContext initializationContext,
                            LogFile logFile)

Description copied from class: AbstractLoggingSystem

Load sensible defaults for the logging system.

Specified by:

loadDefaults in class AbstractLoggingSystem

Parameters:

initializationContext - the logging initialization context

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

loadConfiguration

protected void loadConfiguration(LoggingInitializationContext initializationContext,
                                 String location,
                                 LogFile logFile)

Description copied from class: AbstractLoggingSystem

Load a specific configuration.

Specified by:

loadConfiguration in class AbstractLoggingSystem

Parameters:

initializationContext - the logging initialization context

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

loadConfiguration

protected void loadConfiguration(String location,
                                 LogFile logFile)

getSupportedLogLevels

public Set<LogLevel> getSupportedLogLevels()

Description copied from class: LoggingSystem

Returns a set of the LogLevels that are actually supported by the logging system.

Overrides:

getSupportedLogLevels in class LoggingSystem

Returns:

the supported levels

setLogLevel

public void setLogLevel(String loggerName,
                        LogLevel level)

Description copied from class: LoggingSystem

Sets the logging level for a given logger.

Overrides:

setLogLevel in class LoggingSystem

Parameters:

loggerName - the name of the logger to set (null can be used for the root logger).

level - the log level (null can be used to remove any custom level for the logger and use the default configuration instead)

getLoggerConfigurations

public List<LoggerConfiguration> getLoggerConfigurations()

Description copied from class: LoggingSystem

Returns a collection of the current configuration for all a LoggingSystem's loggers.

Overrides:

getLoggerConfigurations in class LoggingSystem

Returns:

the current configurations

getLoggerConfiguration

public LoggerConfiguration getLoggerConfiguration(String loggerName)

Description copied from class: LoggingSystem

Returns the current configuration for a LoggingSystem's logger.

Overrides:

getLoggerConfiguration in class LoggingSystem

Parameters:

loggerName - the name of the logger

Returns:

the current configuration

getShutdownHandler

public Runnable getShutdownHandler()

Description copied from class: LoggingSystem

Returns a Runnable that can handle shutdown of this logging system when the JVM exits. The default implementation returns null, indicating that no shutdown is required.

Overrides:

getShutdownHandler in class LoggingSystem

Returns:

the shutdown handler, or null

cleanUp

public void cleanUp()

Description copied from class: LoggingSystem

Clean up the logging system. The default implementation does nothing. Subclasses should override this method to perform any logging system-specific cleanup.

Overrides:

cleanUp in class LoggingSystem
