Method Detail

getLog

public Log getLog(String channel)

Description copied from interface: LogFactory

Return a log for the given channel name.

Specified by:

getLog in interface LogFactory

newLogImpl

protected LogFactoryImpl.LogImpl newLogImpl()

Create a new log. The log will be cached.

setDefaultLevel

public void setDefaultLevel(String level)

The string name of the default level for unconfigured log channels; used for automatic configuration.

getDefaultLevel

public short getDefaultLevel()

The default level for unconfigured log channels.

setDefaultLevel

public void setDefaultLevel(short level)

The default level for unconfigured log channels.

setDiagnosticContext

public void setDiagnosticContext(String val)

A string to prefix all log messages with. Set to null to use the configuration's Id property setting.

getDiagnosticContext

public String getDiagnosticContext()

A string to prefix all log messages with. Set to null to use the configuration's Id property setting.

setFile

public void setFile(String file)

The stream to write to. Recognized values are: stdout and stderr. Any other value will be considered a file name.

getStream

public PrintStream getStream()

The stream to write to.

setStream

public void setStream(PrintStream stream)

The stream to write to.

getLevelName

public static String getLevelName(short level)

Returns a string representation of the specified log level constant.

getLevel

public static short getLevel(String str)

Returns a symbolic constant for the specified string level.

setConfiguration

public void setConfiguration(Configuration conf)

Description copied from interface: Configurable

Invoked prior to setting bean properties.

Specified by:

setConfiguration in interface Configurable

startConfiguration

public void startConfiguration()

Description copied from interface: Configurable

Invoked before bean property configuration is begun on this object.

Specified by:

startConfiguration in interface Configurable

endConfiguration

public void endConfiguration()

Description copied from interface: Configurable

Invoked upon completion of bean property configuration for this object.

Specified by:

endConfiguration in interface Configurable

setInto

public void setInto(Options opts)

Description copied from interface: GenericConfigurable

Perform any generic configuration based on the data in opts. This method should remove any values in opts that have been successfully processed; if any values remain in opts after this method is executed, an exception will be thrown identifying those key-value pairs as invalid.

Specified by:

setInto in interface GenericConfigurable
