Class OutputStreamLogSink

java.lang.Object
  org.openqa.jetty.log.OutputStreamLogSink

All Implemented Interfaces:

Serializable, LogSink, LifeCycle

public class OutputStreamLogSink
extends Object
implements LogSink

A Log sink. This class represents both a concrete or abstract sink of Log data. The default implementation logs to System.err, but other output stream or files may be specified. Currently this Stream only writes in ISO8859_1 encoding. For Other encodings use the less efficient WriterLogSink. If a logFilename is specified, output is sent to that file. If the filename contains "yyyy_mm_dd", the log file date format is used to create the actual filename and the log file is rolled over at local midnight. If append is set, existing logfiles are appended to, otherwise a backup is created with a timestamp. Dated log files are deleted after retain days.

If the property LOG_DATE_FORMAT is set, then it is interpreted as a format string for java.text.SimpleDateFormat and used to format the log timestamps. Default value: HH:mm:ss.SSS

If LOG_TIMEZONE is set, it is used to set the timezone of the log date format, otherwise GMT is used.

log

                Object o,
                Frame frame,
                long time)

Log a message. This method formats the log information as a string and calls log(String). It should only be specialized by a derived implementation if the format of the logged messages is to be changed.

Specified by:

log in interface LogSink

Parameters:

tag - Tag for type of log

msg - The message

frame - The frame that generated the message.

time - The time stamp of the message.

log

public void log(String formattedLog)

Log a message. The formatted log string is written to the log sink. The default implementation writes the message to an outputstream.

Specified by:

log in interface LogSink

Parameters:

formattedLog -

start

public void start()

Start a log sink. The default implementation does nothing

Specified by:

start in interface LifeCycle

stop

public void stop()

Stop a log sink. An opportunity for subclasses to clean up. The default implementation does nothing

Specified by:

stop in interface LifeCycle

isStarted

public boolean isStarted()

Specified by:

isStarted in interface LifeCycle

Returns:

True if the LifeCycle has been started.

setLogImpl

public void setLogImpl(LogImpl impl)

Specified by:

setLogImpl in interface LogSink
