Detailed Description

The internal representation of logging events.

When an affirmative decision is made to log then a LoggingEvent instance is created. This instance is passed around to the different log4cxx components.

This class is of concern to those wishing to extend log4cxx.

Member Typedef Documentation

typedef spi::KeySet KeySet

Constructor & Destructor Documentation

LoggingEvent ( )

For serialization only.

LoggingEvent	(	const LogString &	logger,
		const LevelPtr &	level,
		const LogString &	message,
		const log4cxx::spi::LocationInfo &	location
	)

Instantiate a LoggingEvent from the supplied parameters.

Except timeStamp all the other fields of LoggingEvent are filled when actually needed.

Parameters

logger	The logger of this event.
level	The level of this event.
message	The message of this event.
location	location of logging request.

~LoggingEvent ( )

Member Function Documentation

const LevelPtr& getLevel ( ) const

inline

Return the level of this event.

const log4cxx::spi::LocationInfo& getLocationInformation ( ) const

inline

const LogString& getLoggerName ( ) const

inline

Return the name of the logger.

bool getMDC	(	const LogString &	key,
		LogString &	dest
	)		const

Appends the the context corresponding to the key parameter.

If there is a local MDC copy, possibly because we are in a logging server or running inside AsyncAppender, then we search for the key in MDC copy, if a value is found it is returned. Otherwise, if the search in MDC copy returns an empty result, then the current thread's MDC is used.

Note that both the local MDC copy and the current thread's MDC are searched.

Parameters

key	key.
dest	string to which value, if any, is appended.

Returns: true if key had a corresponding value.

void getMDCCopy ( ) const

Obtain a copy of this thread's MDC prior to serialization or asynchronous logging.

KeySet getMDCKeySet ( ) const

Returns the set of of the key values in the MDC for the event.

The returned set is unmodifiable by the caller.

Returns: Set an unmodifiable set of the MDC keys.

const LogString& getMessage ( ) const

inline

Return the message for this logging event.

bool getNDC ( LogString & dest ) const

This method appends the NDC for this event to passed string.

It will return the correct content even if the event was generated in a different thread or even on a different machine. The NDC::get method should never be called directly.

Parameters

dest	destination for NDC, unchanged if NDC is not set.

Returns: true if NDC is set.

bool getProperty	(	const LogString &	key,
		LogString &	dest
	)		const

Return a previously set property.

Parameters

key	key.
dest	string to which value, if any, is appended.

Returns: true if key had a corresponding value.

KeySet getPropertyKeySet ( ) const

Returns the set of of the key values in the properties for the event.

The returned set is unmodifiable by the caller.

Returns: Set an unmodifiable set of the property keys.

const LogString& getRenderedMessage ( ) const

inline

Return the message for this logging event.

static log4cxx_time_t getStartTime ( )

static

Returns the time when the application started, in microseconds elapsed since 01.01.1970.

const LogString& getThreadName ( ) const

inline

Return the threadName of this event.

log4cxx_time_t getTimeStamp ( ) const

inline

The number of microseconds elapsed from 01.01.1970 until logging event was created.

void setProperty	(	const LogString &	key,
		const LogString &	value
	)

Set a string property using a key and a string value.

since 1.3

void write	(	helpers::ObjectOutputStream &	os,
		helpers::Pool &	p
	)		const

Writes the content of the LoggingEvent in a format compatible with log4j's serialized form.
