Class TLcdJULSimpleFormatter

java.lang.Object

java.util.logging.Formatter

com.luciad.util.logging.TLcdJULSimpleFormatter

public class TLcdJULSimpleFormatter
extends Formatter

A formatter for LogRecord messages. The following properties of a LogRecord are used as the argument list to the String.format(String, Object...) method:

1. LogRecord.getMessage()
2. LogRecord.getLoggerName()
3. LogRecord.getLevel()
4. LogRecord.getMillis() as a Date object
5. LogRecord.getSourceClassName()
6. LogRecord.getSourceMethodName()
7. LogRecord.getThreadID()
8. LogRecord.getThrown()

The format string get be set either directly from the setter, or by defining the property com.luciad.util.logging.TLcdJULSimpleFormatter.format in the Java logging properties file.

When the LogRecord contains a Throwable object the corresponding stack trace is also logged immediately after the message. To disable logging of the stack trace you can set the property com.luciad.util.logging.TLcdJULSimpleFormatter.logStackTrace to false

For example, the following two configuration lines:

 java.util.logging.ConsoleHandler.formatter = com.luciad.util.logging.TLcdJULSimpleFormatter
 com.luciad.util.logging.TLcdJULSimpleFormatter.format = %3$s: %1$s (%8$s)\n
 com.luciad.util.logging.TLcdJULSimpleFormatter.logStackTrace = false
 

may display a log message as "SEVERE: An exception occurred (ArrayIndexOutOfBoundsException)". It will not display the stack trace.

Since:

9.0
