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

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

inlinevirtual

No options to activate.

Implements OptionHandler.

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

virtual

Formats a LoggingEvent in conformance with the log4cxx.dtd.

Implements Layout.

bool getLocationInfo ( ) const

inline

Returns the current value of the LocationInfo option.

bool getProperties ( )

inline

Gets whether MDC key-value pairs should be output.

Returns

true if MDC key-value pairs are output.

virtual bool ignoresThrowable ( ) const

inlinevirtual

The XMLLayout prints and does not ignore exceptions.

Hence the return value false.

Implements Layout.

void setLocationInfo ( bool  locationInfo1 )

inline

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.

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

virtual

Set options.

Implements OptionHandler.

void setProperties ( bool  flag )

inline

Sets whether MDC key-value pairs should be output, default false.

Parameters

flag	new value.
