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

inlinevirtual

No options to activate.

Implements OptionHandler.

void appendQuotedEscapedString ( LogString &  buf, const LogString &  input  ) const

protected

void appendSerializedLocationInfo ( LogString &  buf, const spi::LoggingEventPtr &  event, log4cxx::helpers::Pool &  p  ) const

protected

void appendSerializedMDC ( LogString &  buf, const spi::LoggingEventPtr &  event  ) const

protected

void appendSerializedNDC ( LogString &  buf, const spi::LoggingEventPtr &  event  ) const

protected

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

virtual

Implement this method to create your own layout format.

Implements Layout.

virtual LogString getContentType ( ) const

inlinevirtual

Returns the content type output by this layout, i.e "application/json".

Reimplemented from Layout.

bool getLocationInfo ( ) const

inline

Returns the current value of the LocationInfo option.

bool getPrettyPrint ( ) const

inline

Returns the current value of the PrettyPrint option.

virtual bool ignoresThrowable ( ) const

inlinevirtual

The JSON layout handles the throwable contained in logging events.

Hence, this method return false.

Implements Layout.

void setLocationInfo ( bool  locationInfoFlag )

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.

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

virtual

Set options.

Implements OptionHandler.

void setPrettyPrint ( bool  prettyPrintFlag )

inline

The PrettyPrint option takes a boolean value.

By default, it is set to false which means output by this layout will be one line per log event. If the option is set to true, then then each log event will produce multiple lines, each indented for readability.
