Constructor & Destructor Documentation

log4cpp::AppenderSkeleton::AppenderSkeleton (  const std::string &    name )  [protected]

Constructor for AppenderSkeleton. Will only be used in getAppender() (and in derived classes of course). Parameters: name  The name of this Appender.

log4cpp::AppenderSkeleton::~AppenderSkeleton (    )  [virtual]

Destructor for AppenderSkeleton.

Member Function Documentation

virtual void log4cpp::AppenderSkeleton::_append (  const LoggingEvent &    event )  [protected, pure virtual]

Log in Appender specific way. Subclasses of Appender should implement this method to perform actual logging. Parameters: event  The LoggingEvent to log. Implemented in log4cpp::FileAppender.

virtual void log4cpp::AppenderSkeleton::close (    )  [pure virtual]

Release any resources allocated within the appender such as file handles, network connections, etc. Implements log4cpp::Appender. Implemented in log4cpp::FileAppender.

void log4cpp::AppenderSkeleton::doAppend (  const LoggingEvent &    event )  [virtual]

Log in Appender specific way. Parameters: event  The LoggingEvent to log. Implements log4cpp::Appender.

Filter * log4cpp::AppenderSkeleton::getFilter (    )  [virtual]

Get the Filter for this appender. Returns: the filter, or NULL if no filter has been set. Implements log4cpp::Appender.

Priority::Value log4cpp::AppenderSkeleton::getThreshold (    )  [virtual]

Get the threshold priority of this Appender. Returns: the threshold Implements log4cpp::Appender.

bool log4cpp::AppenderSkeleton::reopen (    )  [virtual]

Reopens the output destination of this Appender, e.g. the logfile or TCP socket. Returns: false if an error occured during reopening, true otherwise. Implements log4cpp::Appender. Reimplemented in log4cpp::FileAppender.

virtual bool log4cpp::AppenderSkeleton::requiresLayout (    )  const [pure virtual]

Check if the appender uses a layout. Returns: true if the appender implementation requires a layout. Implements log4cpp::Appender. Implemented in log4cpp::IdsaAppender.

void log4cpp::AppenderSkeleton::setFilter (  Filter *    filter )  [virtual]

Set a Filter for this appender. Implements log4cpp::Appender.

virtual void log4cpp::AppenderSkeleton::setLayout (  Layout *    layout )  [pure virtual]

Set the Layout for this appender. Parameters: layout  The layout to use. Implements log4cpp::Appender. Implemented in log4cpp::IdsaAppender.

void log4cpp::AppenderSkeleton::setThreshold (  Priority::Value    priority )  [virtual]

Set the threshold priority of this Appender. The Appender will not appender LoggingEvents with a priority lower than the threshold. Use Priority::NOTSET to disable threshold checking. Parameters: priority  The priority to set. Implements log4cpp::Appender.
