The BufferingForwardingAppender type exposes the following members.

	Name	Description
	BufferingForwardingAppender	Initializes a new instance of the BufferingForwardingAppender class.

	Name	Description
	Appenders	Gets the appenders contained in this appender as an ICollection.
	BufferSize	Gets or sets the size of the cyclic buffer used to hold the logging events. (Inherited from BufferingAppenderSkeleton.)
	ErrorHandler	Gets or sets the IErrorHandler for this appender. (Inherited from AppenderSkeleton.)
	Evaluator	Gets or sets the ITriggeringEventEvaluator that causes the buffer to be sent immediately. (Inherited from BufferingAppenderSkeleton.)
	FilterHead	The filter chain. (Inherited from AppenderSkeleton.)
	Fix	Gets or sets a the fields that will be fixed in the event (Inherited from BufferingAppenderSkeleton.)
	Layout	Gets or sets the ILayout for this appender. (Inherited from AppenderSkeleton.)
	Lossy	Gets or sets a value that indicates whether the appender is lossy. (Inherited from BufferingAppenderSkeleton.)
	LossyEvaluator	Gets or sets the value of the ITriggeringEventEvaluator to use. (Inherited from BufferingAppenderSkeleton.)
	Name	Gets or sets the name of this appender. (Inherited from AppenderSkeleton.)
	OnlyFixPartialEventData	Obsolete. Gets or sets a value indicating if only part of the logging event data should be fixed. (Inherited from BufferingAppenderSkeleton.)
	RequiresLayout	Tests if this appender requires a Layout to be set. (Inherited from AppenderSkeleton.)
	Threshold	Gets or sets the threshold Level of this appender. (Inherited from AppenderSkeleton.)

	Name	Description
	ActivateOptions	Initialize the appender based on the options set (Inherited from BufferingAppenderSkeleton.)
	AddAppender	Adds an IAppender to the list of appenders of this instance.
	AddFilter	Adds a filter to the end of the filter chain. (Inherited from AppenderSkeleton.)
	Append(LoggingEvent)	Append a bulk array of logging events. (Inherited from AppenderSkeleton.)
	Append(LoggingEvent)	This method is called by the DoAppend(LoggingEvent) method. (Inherited from BufferingAppenderSkeleton.)
	ClearFilters	Clears the filter list for this appender. (Inherited from AppenderSkeleton.)
	Close	Closes the appender and release resources. (Inherited from AppenderSkeleton.)
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent)] method. (Inherited from AppenderSkeleton.)
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent[])] method. (Inherited from AppenderSkeleton.)
	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 (Inherited from AppenderSkeleton.)
	Finalize	Finalizes this appender by calling the implementation's Close method. (Inherited from AppenderSkeleton.)
	Flush	Flush the currently buffered events (Inherited from BufferingAppenderSkeleton.)
	Flush(Boolean)	Flush the currently buffered events (Inherited from BufferingAppenderSkeleton.)
	Flush(Int32)	Flushes any buffered log data. (Inherited from BufferingAppenderSkeleton.)
	GetAppender	Looks for the appender with the specified name.
	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. (Inherited from AppenderSkeleton.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnClose	Closes the appender and releases resources. (Overrides BufferingAppenderSkeletonOnClose.)
	PreAppendCheck	Called before [M:Append(LoggingEvent)] as a precondition. (Inherited from AppenderSkeleton.)
	RemoveAllAppenders	Removes all previously added appenders from this appender.
	RemoveAppender(String)	Removes the appender with the specified name from the list of appenders.
	RemoveAppender(IAppender)	Removes the specified appender from the list of appenders.
	RenderLoggingEvent(LoggingEvent)	Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
	RenderLoggingEvent(TextWriter, LoggingEvent)	Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
	SendBuffer	Send the events. (Overrides BufferingAppenderSkeletonSendBuffer(LoggingEvent).)
	SendFromBuffer	Sends the contents of the buffer. (Inherited from BufferingAppenderSkeleton.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

The events are buffered in this appender until conditions are met to allow the appender to deliver the events to the attached appenders. See BufferingAppenderSkeleton for the conditions that cause the buffer to be sent.

The forwarding appender can be used to specify different thresholds and filters for the same appender at different locations within the hierarchy.
