Detailed Description

The output of the XMLLayout consists of a series of log4j:event elements.

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.

Member Function Documentation

◆ activateOptions()

void log4cxx::xml::XMLLayout::activateOptions ( helpers::Pool & )

inlineoverridevirtual

No options to activate.

Implements log4cxx::spi::OptionHandler.

◆ format()

void log4cxx::xml::XMLLayout::format	(	LogString &	output,
		const spi::LoggingEventPtr &	event,
		helpers::Pool &	p
	)		const

overridevirtual

Formats a LoggingEvent in conformance with the log4cxx.dtd.

Implements log4cxx::Layout.

◆ getLocationInfo()

bool log4cxx::xml::XMLLayout::getLocationInfo ( ) const

Returns the current value of the LocationInfo option.

◆ getProperties()

bool log4cxx::xml::XMLLayout::getProperties ( )

Gets whether MDC key-value pairs should be output.

Returns: true if MDC key-value pairs are output.

◆ ignoresThrowable()

bool log4cxx::xml::XMLLayout::ignoresThrowable ( ) const

inlineoverridevirtual

The XMLLayout prints and does not ignore exceptions.

Hence the return value false.

Implements log4cxx::Layout.

◆ setLocationInfo()

void log4cxx::xml::XMLLayout::setLocationInfo ( bool locationInfo1 )

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.

◆ setOption()

void log4cxx::xml::XMLLayout::setOption	(	const LogString &	option,
		const LogString &	value
	)

overridevirtual

Set options.
