Properties

	Name	Description
	ErrorHandler	Gets or sets the IErrorHandler for this appender.
	FilterHead	The filter chain.
	Layout	Gets or sets the ILayout for this appender.

Methods

	Name	Description
	ActivateOptions	Initialize the appender based on the options set
	AddFilter	Adds a filter to the end of the filter chain.
	Append(LoggingEvent)	Subclasses of AppenderSkeleton should implement this method to perform actual logging.
	Append(LoggingEvent[])	Append a bulk array of logging events.
	ClearFilters	Clears the filter list for this appender.
	Close	Closes the appender and release resources.
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent)] method.
	DoAppend(LoggingEvent[])	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent[])] method.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	FilterEvent	Test if the logging event should we output by this appender
	Finalize	Finalizes this appender by calling the implementation's Close() method. (Overrides Object.Finalize().)
	Flush	Flushes any buffered log data.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsAsSevereAsThreshold	Checks if the message level is below this appender's threshold.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnClose	Is called when the appender is closed. Derived classes should override this method if resources need to be released.
	PreAppendCheck	Called before [M:Append(LoggingEvent)] as a precondition.
	RenderLoggingEvent(LoggingEvent)	Renders the LoggingEvent to a string.
	RenderLoggingEvent(TextWriter, LoggingEvent)	Renders the LoggingEvent to a string.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Remarks

This class provides the code for common functionality, such as support for threshold filtering and support for general filters.

Appenders can also implement the IOptionHandler interface. Therefore they would require that the [M:IOptionHandler.ActivateOptions()] method be called after the appenders properties have been configured.
