Detailed Description

FileAppender appends log events to a file.

Support for java.io.Writer and console appending has been deprecated and then removed. See the replacement solutions: WriterAppender and ConsoleAppender.

Constructor & Destructor Documentation

FileAppender ( )

The default constructor does not do anything.

FileAppender	(	const LayoutPtr &	layout,
		const LogString &	filename,
		bool	append,
		bool	bufferedIO,
		int	bufferSize
	)

Instantiate a FileAppender and open the file designated by filename.

The opened filename will become the output destination for this appender.

If the append parameter is true, the file will be appended to. Otherwise, the file designated by filename will be truncated before being opened.

If the bufferedIO parameter is true, then buffered IO will be used to write to the output file.

FileAppender	(	const LayoutPtr &	layout,
		const LogString &	filename,
		bool	append
	)

Instantiate a FileAppender and open the file designated by filename.

The opened filename will become the output destination for this appender.

If the append parameter is true, the file will be appended to. Otherwise, the file designated by filename will be truncated before being opened.

FileAppender	(	const LayoutPtr &	layout,
		const LogString &	filename
	)

Instantiate a FileAppender and open the file designated by filename.

The opened filename will become the output destination for this appender.

The file will be appended to.

~FileAppender ( )

Member Function Documentation

void activateOptions ( log4cxx::helpers::Pool & p )

virtual

Sets and opens the file where the log output will go. The specified file must be writable.

If there was already an opened file, then the previous file is closed first.

Reimplemented from WriterAppender.

Reimplemented in RollingFileAppender, and RollingFileAppenderSkeleton.

bool getAppend ( ) const

inline

Returns the value of the Append option.

bool getBufferedIO ( ) const

inline

Get the value of the BufferedIO option.

BufferedIO will significatnly increase performance on heavily loaded systems.

int getBufferSize ( ) const

inline

Get the size of the IO buffer.

LogString getFile ( ) const

inline

Returns the value of the File option.

void setAppend ( bool fileAppend1 )

The Append option takes a boolean value.

It is set to true by default. If true, then File will be opened in append mode by setFile (see above). Otherwise, setFile will open File in truncate mode.

Note: Actual opening of the file is made when activateOptions is called, not when the options are set.

void setBufferedIO ( bool bufferedIO )

The BufferedIO option takes a boolean value.

It is set to false by default. If true, then File will be opened in buffered mode.

BufferedIO will significantly increase performance on heavily loaded systems.

void setBufferSize ( int bufferSize1 )

inline

Set the size of the IO buffer.

virtual void setFile ( const LogString & file )

virtual

The File property takes a string value which should be the name of the file to append to.

Note that the special values "System.out" or "System.err" are no longer honored.

Note: Actual opening of the file is made when activateOptions is called, not when the options are set.

virtual void setFile	(	const LogString &	file,
		bool	append,
		bool	bufferedIO,
		size_t	bufferSize,
		log4cxx::helpers::Pool &	p
	)

virtual

Sets and opens the file where the log output will go.

The specified file must be writable.

If there was already an opened file, then the previous file is closed first.

Do not use this method directly. To configure a FileAppender or one of its subclasses, set its properties one by one and then call activateOptions.

Parameters

file	The path to the log file.
append	If true will append to fileName. Otherwise will truncate fileName.
bufferedIO	Do we do bufferedIO?
bufferSize	How big should the IO buffer be?
p	memory pool for operation.

void setOption	(	const LogString &	option,
		const LogString &	value
	)

virtual

Set option to value.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.

Reimplemented from AppenderSkeleton.

Reimplemented in RollingFileAppender.

static LogString stripDuplicateBackslashes ( const LogString & name )

static

Replaces double backslashes with single backslashes for compatibility with paths from earlier XML configurations files.

Parameters

name file name

Returns: corrected file name

Member Data Documentation

bool bufferedIO

protected

Do we do bufferedIO?

int bufferSize

protected

How big should the IO buffer be? Default is 8K.

bool fileAppend

protected

Append to or truncate the file? The default value for this variable is true, meaning that by default a FileAppender will append to an existing file and not truncate it.

This option is meaningful only if the FileAppender opens the file.

LogString fileName

protected

The name of the log file.
