Detailed Description

This Category subclass replaces the NDC field in LoggingEvents with a fixed context string.

All handling of Appenders, etc. is delgated to the 'normal' Category with the same name. Its intended use is for object instances that serve a single client: they contruct a FixedContextCategory with the client identifier as context. Unlike with regular Category instances one has to explicitly create FixedContextCategory instances using the constructor. This also implies one has to take cake of destruction of the instance as well.

Since: 0.2.4

Constructor & Destructor Documentation

FixedContextCategory::FixedContextCategory	(	const std::string &	name,
		const std::string &	context = `""`
	)

Constructor.

Parameters

name	the fully qualified name of this Categories delegate Category.
context	the context to fill the NDC field of LoggingEvents with.

virtual FixedContextCategory::~FixedContextCategory ( )

virtual

Destructor for Category.

Member Function Documentation

virtual void FixedContextCategory::_logUnconditionally2	(	Priority::Value	priority,
		const std::string &	message
	)
throw	(
	)

protectedvirtual

Unconditionally log a message with the specified priority.

Parameters

priority	The priority of this log message.
message	string to write in the log file

Reimplemented from Category.

virtual void FixedContextCategory::addAppender	(	Appender *	appender	)
throw	(
	)

virtual

For the moment this method does nothing.

Reimplemented from Category.

virtual void FixedContextCategory::addAppender ( Appender & appender )

virtual

For the moment this method does nothing.

Reimplemented from Category.

virtual void FixedContextCategory::callAppenders	(	const LoggingEvent &	event	)
throw	(
	)

virtual

Call the appenders in the hierarchy starting at this.

If no appenders could be found, emit a warning.

This method always calls all the appenders inherited form the hierracy circumventing any evaluation of whether to log or not to log the particular log request.

Parameters

event The LoggingEvent to log.

Reimplemented from Category.

virtual bool FixedContextCategory::getAdditivity	(	)	const
throw	(
	)

virtual

Returns the additivity flag for this Category instance.

Reimplemented from Category.

virtual AppenderSet FixedContextCategory::getAllAppenders ( ) const

virtual

Returns the set of Appenders currently attached to this Catogory.

Since: 0.3.1

Returns: The set of attached Appenders.

Reimplemented from Category.

virtual Appender* FixedContextCategory::getAppender ( ) const

virtual

Returns the Appender for this Category, or NULL if no Appender has been set.

Returns: The Appender.

Reimplemented from Category.

virtual Appender* FixedContextCategory::getAppender ( const std::string & name ) const

virtual

Returns the specified Appender for this Category, or NULL if the Appender is not attached to this Category.

Since: 0.2.7

Returns: The Appender.

Reimplemented from Category.

virtual Priority::Value FixedContextCategory::getChainedPriority	(	)	const
throw	(
	)

virtual

Starting from this Category, search the category hierarchy for a set priority and return it.

Otherwise, return the priority of the root category.

The Category class is designed so that this method executes as quickly as possible.

Reimplemented from Category.

virtual std::string FixedContextCategory::getContext ( ) const

virtual

Return the context string used as NDC.

Returns: the context string.

virtual Priority::Value FixedContextCategory::getPriority	(	)	const
throw	(
	)

virtual

Returns the assigned Priority, if any, for this Category.

Returns: Priority - the assigned Priority, can be Priority::NOTSET

Reimplemented from Category.

virtual bool FixedContextCategory::ownsAppender	(	)	const
throw	(
	)

virtual

FixedContextAppenders cannot own Appenders.

Returns: false

Reimplemented from Category.

virtual bool FixedContextCategory::ownsAppender	(	Appender *	appender	)	const
throw	(
	)

virtual

FixedContextAppenders cannot own Appenders.

Returns: false

Reimplemented from Category.

virtual void FixedContextCategory::removeAllAppenders ( )

virtual

Removes all appenders set for this Category.

Currently a Category can have only one appender, but this may change in the future.

Reimplemented from Category.

virtual void FixedContextCategory::setAdditivity ( bool additivity )

virtual

Set the additivity flag for this Category instance.

Reimplemented from Category.

virtual void FixedContextCategory::setContext ( const std::string & context )

virtual

Set the context string used as NDC.

Parameters

context the context string
