public class PeriodicSizeRotatingFileHandler
extends PeriodicRotatingFileHandler

A file handler which rotates the log at a preset time interval or the size of the log.

The time interval is determined by the content of the suffix string which is passed in to PeriodicRotatingFileHandler.setSuffix(String).

The size interval is determined by the value passed in the setRotateSize(long).

Method Details

setOutputStream

public void setOutputStream(OutputStream outputStream)

Description copied from class: OutputStreamHandler

Set the output stream to write to.

Overrides:

setOutputStream in class OutputStreamHandler

Parameters:

outputStream - the new output stream or null for none

setFile

public void setFile(File file)
             throws FileNotFoundException

Set the output file.

Overrides:

setFile in class PeriodicRotatingFileHandler

Parameters:

file - the file

Throws:

RuntimeException - if there is an attempt to rotate file and the rotation fails

FileNotFoundException - if an error occurs opening the file

isRotateOnBoot

public boolean isRotateOnBoot()

Indicates whether or a not the handler should rotate the file before the first log record is written.

Returns:

true if file should rotate on boot, otherwise false/

setRotateOnBoot

public void setRotateOnBoot(boolean rotateOnBoot)

Set to a value of true if the file should be rotated before the a new file is set. The rotation only happens if the file names are the same and the file has a length greater than 0.

Parameters:

rotateOnBoot - true to rotate on boot, otherwise false

setRotateSize

public void setRotateSize(long rotateSize)

Set the rotation size, in bytes.

Parameters:

rotateSize - the number of bytes before the log is rotated

setMaxBackupIndex

public void setMaxBackupIndex(int maxBackupIndex)

Set the maximum backup index (the number of log files to keep around).

Parameters:

maxBackupIndex - the maximum backup index

preWrite

protected void preWrite(ExtLogRecord record)

Description copied from class: PeriodicRotatingFileHandler

Execute any pre-write policy, such as file rotation. The write lock is held during this method, so make it quick. The default implementation does nothing. This implementation checks to see if the scheduled rollover time has yet occurred.

Overrides:

preWrite in class PeriodicRotatingFileHandler

Parameters:

record - the record about to be logged

rotate

private void rotate(File file)
             throws IOException

Throws:

IOException
