Class LoggerHelper.LogRecord

java.lang.Object

fr.ifremer.isisfish.logging.LoggerHelper.LogRecord

All Implemented Interfaces:

Serializable

Enclosing class:

LoggerHelper

public static class LoggerHelper.LogRecord
extends Object
implements Serializable

This is a log record (says an entry of a log file). This is abstracted from any logging implementation. To deal with log, we don't use string version stored in original log file, prefer use serialized form of a LogRecord : we keep a lot of time when using them to display them in ui, and for filtering process too. The LogRecord unicity is base on two properties :

• timestamp
• message

We can not use only timestamp, more than one event could appear in a same timestamp. TODO Put this code in lutinLog ?

Field Summary

Fields

Modifier and Type	Field and Description
protected int	level the severity of the event
protected String	message the msg for the event
protected long	offset the offset of logRecord in stream.
protected String	text the string represention of logEvent, transient since we use a lazy getter we don't need to store it.
protected String[]	throwableStrRep the throwable details the event
protected long	timeStamp the time of the event

Field Detail

timeStamp

protected long timeStamp

the time of the event

message

protected String message

the msg for the event

level

protected int level

the severity of the event

throwableStrRep

protected String[] throwableStrRep

the throwable details the event

text

protected transient String text

the string represention of logEvent, transient since we use a lazy getter we don't need to store it. (if not transient : double the size of serialized form...)

offset

protected transient long offset

the offset of logRecord in stream. This is a transient property, since we compute this value when getting the LogRecord from stream

We base the identiy of a LogEvent on the message, level and timestamp

Overrides:

equals in class Object

o - object to compare

Returns:

true if same object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
