log4tango::Appender::~Appender () [virtual]¶
Destructor for Appender.
Member Function Documentation¶
virtual int log4tango::Appender::_append (const LoggingEvent & event) [protected], [pure virtual]¶
Log in Appender specific way. Subclasses of Appender should implement this method to perform actual logging.
Parameters
Implemented in log4tango::FileAppender, log4tango::OstreamAppender, and log4tango::RollingFileAppender.
int log4tango::Appender::append (const LoggingEvent & event) [inline]¶
Log in Appender specific way. Returns -1 on error, 0 otherwise.
Parameters
virtual void log4tango::Appender::close (void) [pure virtual]¶
Release any resources allocated within the appender such as file handles, network connections, etc.
Implemented in log4tango::OstreamAppender, and log4tango::FileAppender.
const std::string & log4tango::Appender::get_name (void) const [inline]¶
Returns this appender name.
bool log4tango::Appender::is_valid (void) const [virtual]¶
Check if the appender is valid (for instance the underlying connection is ok) This default implementation always return true. Overload to define your own behaviour.
Returns
Reimplemented in log4tango::FileAppender.
void log4tango::Appender::level_changed (Level::Value new_level) [protected], [virtual]¶
Inform an appender that its Logger's logging level has changed. The default implementation does nothing.
Parameters
bool log4tango::Appender::reopen (void) [virtual]¶
Reopens the output destination of this Appender, e.g. the logfile or TCP socket.
Returns
Reimplemented in log4tango::OstreamAppender, and log4tango::FileAppender.
virtual bool log4tango::Appender::requires_layout (void) const [pure virtual]¶
Check if the appender uses a layout.
