It does not output a complete well-formed XML file. The output is designed to be included as an external entity in a separate file to form a correct XML file.
For example, if abc is the name of the file where the XMLLayout ouput goes, then a well-formed XML file would be:
<?xml version="1.0" ?>
<!DOCTYPE log4j:eventSet [<!ENTITY data SYSTEM "abc">]>
<log4j:eventSet version="1.2" xmlns:log4j="http://jakarta.apache.org/log4j/">
@&data;
</log4j:eventSet>
This approach enforces the independence of the XMLLayout and the appender where it is embedded.
Activate the options that were previously set with calls to option setters.
No action is performed in this implementation.
Implements log4cxx::spi::OptionHandler.
Formats a LoggingEvent in conformance with the log4cxx.dtd.
Implements log4cxx::Layout.
Returns the current value of the LocationInfo option.
The XMLLayout prints and does not ignore exceptions.
Hence the return value false.
Implements log4cxx::Layout.
The LocationInfo option takes a boolean value.
By default, it is set to false which means there will be no location information output by this layout. If the the option is set to true, then the file name and line number of the statement at the origin of the log statement will be output.
If you are embedding this layout within a SMTPAppender then make sure to set the LocationInfo option of that appender as well.
Set option to value.
| Supported options | Supported values | Default value |
|---|---|---|
| Properties | True,False | False |
| LocationInfo | True,False | False |
Implements log4cxx::spi::OptionHandler.
Sets whether MDC key-value pairs should be output, default false.
