Detailed Description

ConsoleAppender appends log events to stdout or stderr using a layout specified by the user.

The default target is stdout.

Constructor & Destructor Documentation

ConsoleAppender() [1/3]

log4cxx::ConsoleAppender::ConsoleAppender

(

)

A stdout log event appender.

See also setLayout and setTarget.

ConsoleAppender() [2/3]

log4cxx::ConsoleAppender::ConsoleAppender

(

const LayoutPtr &

layout

)

A stdout log event appender formatted using layout.

Parameters

layout

formats a log event

ConsoleAppender() [3/3]

log4cxx::ConsoleAppender::ConsoleAppender	(	const LayoutPtr &	layout,
		const LogString &	target )

A target log event appender formatted using layout.

Parameters

layout	formats a log event
target	the value provided by getSystemOut or getSystemErr

~ConsoleAppender()

log4cxx::ConsoleAppender::~ConsoleAppender

)

Member Function Documentation

activateOptions()

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

overridevirtual

Derived appenders should override this method if option structure requires it.

Reimplemented from log4cxx::AppenderSkeleton.

getSystemErr()

static const LogString & log4cxx::ConsoleAppender::getSystemErr ( )

static

Returns

the name recognised as stderr.

getSystemOut()

static const LogString & log4cxx::ConsoleAppender::getSystemOut ( )

static

Returns

the name recognised as stdout.

getTarget()

LogString log4cxx::ConsoleAppender::getTarget

(

)

const

Returns

the current value of the target property.

setOption()

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

overridevirtual

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 log4cxx::AppenderSkeleton.

setTarget()

void log4cxx::ConsoleAppender::setTarget

(

const LogString &

newValue

)

Use newValue for the target property.

Parameters

newValue

the value provided by getSystemOut or getSystemErr
