 org.apache.commons.discovery.log.SimpleLog
| SimpleLog | | public class SimpleLog implements Log(Code) | | Simple implementation of Log that sends all enabled log messages,
for all defined loggers, to System.err.
Hacked from commons-logging SimpleLog for use in discovery.
This is intended to be enough of a Log implementation to bootstrap
Discovery.
One property: org.apache.commons.discovery.log.level.
valid values: all, trace, debug, info, warn, error, fatal, off.

| Constructor Summary | |
| public | SimpleLog(String name)
Construct a simple log with given name. |
| Method Summary | |
| final public void | debug(Object message)
| | final public void | debug(Object message, Throwable t)
| | final public void | error(Object message)
| | final public void | error(Object message, Throwable t)
| | final public void | fatal(Object message)
| | final public void | fatal(Object message, Throwable t)
| | public static int | getLevel()
Get logging level. | | final public void | info(Object message)
| | final public void | info(Object message, Throwable t)
| | final public boolean | isDebugEnabled()
Are debug messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger. | | final public boolean | isErrorEnabled()
Are error messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger. | | final public boolean | isFatalEnabled()
Are fatal messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger. | | final public boolean | isInfoEnabled()
Are info messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger. | | protected static boolean | isLevelEnabled(int level)
| | final public boolean | isTraceEnabled()
Are trace messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger. | | final public boolean | isWarnEnabled()
Are warn messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger. | | protected void | log(int type, Object message, Throwable t)
Do the actual logging. | | public static void | setLevel(int currentLogLevel)
Set logging level. | | final public void | trace(Object message)
| | final public void | trace(Object message, Throwable t)
| | final public void | warn(Object message)
| | final public void | warn(Object message, Throwable t)
|
| LOG_LEVEL_ALL | | final public static int LOG_LEVEL_ALL(Code) | | Enable all logging levels
|
| LOG_LEVEL_DEBUG | | final public static int LOG_LEVEL_DEBUG(Code) | | "Debug" level logging.
|
| LOG_LEVEL_ERROR | | final public static int LOG_LEVEL_ERROR(Code) | | "Error" level logging.
|
| LOG_LEVEL_FATAL | | final public static int LOG_LEVEL_FATAL(Code) | | "Fatal" level logging.
|
| LOG_LEVEL_INFO | | final public static int LOG_LEVEL_INFO(Code) | | "Info" level logging.
|
| LOG_LEVEL_OFF | | final public static int LOG_LEVEL_OFF(Code) | | Enable no logging levels
|
| LOG_LEVEL_TRACE | | final public static int LOG_LEVEL_TRACE(Code) | | "Trace" level logging.
|
| LOG_LEVEL_WARN | | final public static int LOG_LEVEL_WARN(Code) | | "Warn" level logging.
|
| dateFormatter | | protected static DateFormat dateFormatter(Code) | | Used to format times
|
| logLevel | | protected static int logLevel(Code) | | The current log level
|
| logName | | protected String logName(Code) | | The name of this simple log instance
|
| showDateTime | | protected static boolean showDateTime(Code) | | Include the current time in the log message
|
| showLogName | | protected static boolean showLogName(Code) | | Include the instance name in the log message?
|
| showShortName | | protected static boolean showShortName(Code) | | Include the short name ( last component ) of the logger in the log
message. Default to true - otherwise we'll be lost in a flood of
messages without knowing who sends them.
|
| SimpleLog | | public SimpleLog(String name)(Code) | | Construct a simple log with given name.
Parameters:
name - log name |
| debug | | final public void debug(Object message)(Code) | | Log a message with debug log level.
|
| error | | final public void error(Object message)(Code) | | Log a message with error log level.
|
| fatal | | final public void fatal(Object message)(Code) | | Log a message with fatal log level.
|
| getLevel | | public static int getLevel()(Code) | | Get logging level.
|
| info | | final public void info(Object message)(Code) | | Log a message with info log level.
|
| isDebugEnabled | | final public boolean isDebugEnabled()(Code) | | Are debug messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger.
|
| isErrorEnabled | | final public boolean isErrorEnabled()(Code) | | Are error messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger.
|
| isFatalEnabled | | final public boolean isFatalEnabled()(Code) | | Are fatal messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger.
|
| isInfoEnabled | | final public boolean isInfoEnabled()(Code) | | Are info messages currently enabled?
This allows expensive operations such as String
concatenation to be avoided when the message will be ignored by the
logger.
|
