Constructor Detail

LogRecord

public LogRecord(Level level, String message)
Constructs a LogRecord given a severity level and an unlocalized message text. In addition, the sequence number, creation time (as returned by getMillis()) and thread ID are assigned. All other properties are set to null.

Parameters: level the severity level, for example Level.WARNING. message the message text (which will be used as key for looking up the localized message text if a resource bundle has been associated).

Method Detail

getLevel

public Level getLevel()
Returns the level of the LogRecord.

Applications should be aware of the possibility that the result is not necessarily one of the standard logging levels, since the logging framework allows to create custom subclasses of java.util.logging.Level. Therefore, filters should perform checks like theRecord.getLevel().intValue() == Level.INFO.intValue() instead of theRecord.getLevel() == Level.INFO.

getLoggerName

public String getLoggerName()
Returns the name of the logger where this LogRecord has originated.

Returns: the name of the source {@link Logger}, or null if this LogRecord does not originate from a Logger.

getMessage

public String getMessage()
Returns the message for this LogRecord before any localization or parameter substitution.

A {@link Logger} will try to localize the message if a resource bundle has been associated with this LogRecord. In this case, the logger will call getMessage() and use the result as the key for looking up the localized message in the bundle. If no bundle has been associated, or if the result of getMessage() is not a valid key in the bundle, the logger will use the raw message text as returned by this method.

Returns: the message text, or null if there is no message text.

getMillis

public long getMillis()
Returns the time when this LogRecord was created.

Returns: the time of creation in milliseconds since the beginning of January 1, 1970.

getParameters

public Object[] getParameters()
Returns the parameters to the log message.

Returns: the parameters to the message, or null if the message has no parameters.

getResourceBundle

public ResourceBundle getResourceBundle()
Returns the resource bundle that is used when the message of this LogRecord needs to be localized.

Returns: the resource bundle used for localization, or null if this message does not need to be localized.

getResourceBundleName

public String getResourceBundleName()
Returns the name of the resource bundle that is used when the message of this LogRecord needs to be localized.

Returns: the name of the resource bundle used for localization, or null if this message does not need to be localized.

getSequenceNumber

public long getSequenceNumber()
Returns the sequence number of this LogRecord.

getSourceClassName

public String getSourceClassName()
Returns the name of the class where the event being logged has had its origin. This information can be passed as parameter to some logging calls, and in certain cases, the logging framework tries to determine an approximation (which may or may not be accurate).

Returns: the name of the class that issued the logging request, or null if this information could not be obtained.

getSourceMethodName

public String getSourceMethodName()
Returns the name of the method where the event being logged has had its origin. This information can be passed as parameter to some logging calls, and in certain cases, the logging framework tries to determine an approximation (which may or may not be accurate).

Returns: the name of the method that issued the logging request, or null if this information could not be obtained.

getThreadID

public int getThreadID()
Returns an identifier for the thread in which this LogRecord was created. The identifier is not necessarily related to any thread identifiers used by the operating system.

Returns: an identifier for the source thread.

getThrown

public Throwable getThrown()
Returns the Throwable associated with this LogRecord, or null if the logged event is not related to an exception or error.

setLevel

public void setLevel(Level level)
Sets the severity level of this LogRecord to a new value.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.

Parameters: level the new severity level, for example Level.WARNING.

setLoggerName

public void setLoggerName(String name)
Sets the name of the logger where this LogRecord has originated.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.

Parameters: name the name of the source logger, or null to indicate that this LogRecord does not originate from a Logger.

setMessage

public void setMessage(String message)
Sets the message for this LogRecord.

A Logger will try to localize the message if a resource bundle has been associated with this LogRecord. In this case, the logger will call getMessage() and use the result as the key for looking up the localized message in the bundle. If no bundle has been associated, or if the result of getMessage() is not a valid key in the bundle, the logger will use the raw message text as returned by this method.

It is possible to set the message to either an empty String or null, although this does not make the the message very helpful to human users.

Parameters: message the message text (which will be used as key for looking up the localized message text if a resource bundle has been associated).

setMillis

public void setMillis(long millis)
Sets the time when this LogRecord was created.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.

Parameters: millis the time of creation in milliseconds since the beginning of January 1, 1970.

setParameters

public void setParameters(Object[] parameters)
Sets the parameters to the log message.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.

Parameters: parameters the parameters to the message, or null to indicate that the message has no parameters.

setResourceBundle

public void setResourceBundle(ResourceBundle bundle)
Sets the resource bundle that is used when the message of this LogRecord needs to be localized.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.

Parameters: bundle the resource bundle to be used, or null to indicate that this message does not need to be localized.

setResourceBundleName

public void setResourceBundleName(String name)
Sets the name of the resource bundle that is used when the message of this LogRecord needs to be localized.

Parameters: seqNum the new sequence number.

setSourceClassName

public void setSourceClassName(String sourceClassName)
Sets the name of the class where the event being logged has had its origin.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.

Parameters: sourceClassName the name of the class that issued the logging request, or null to indicate that this information could not be obtained.

setSourceMethodName

public void setSourceMethodName(String sourceMethodName)
Sets the name of the method where the event being logged has had its origin.

As soon as a LogRecord has been handed over to the logging framework, applications should not modify it anymore. Therefore, this method should only be called on freshly constructed LogRecords.
