virtual void | setFile (const LogString &file) |

Static Public Member Functions | |
static LogString | stripDuplicateBackslashes (const LogString &name) |
Replaces double backslashes with single backslashes for compatibility with paths from earlier XML configurations files. | |
Protected Attributes | |
bool | fileAppend |
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. | |
LogString | fileName |
The name of the log file. | |
bool | bufferedIO |
Do we do bufferedIO? | |
int | bufferSize |
How big should the IO buffer be? Default is 8K. |
Support for java.io.Writer
and console appending has been deprecated and then removed. See the replacement solutions: WriterAppender and ConsoleAppender.
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 | ( | ) |
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 DailyRollingFileAppender, RollingFileAppenderSkeleton, and RollingFileAppender.
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.
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, | |
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.
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. |
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.
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 WriterAppender.
Reimplemented in DailyRollingFileAppender, and RollingFileAppender.
Replaces double backslashes with single backslashes for compatibility with paths from earlier XML configurations files.
name | file name |
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.
