            This base class should be used by appenders that need to buffer a 
            number of events before logging them. For example the <a href="T_log4net_Appender_AdoNetAppender.htm">AdoNetAppender</a> 
            buffers events and then submits the entire contents of the buffer to 
            the underlying database in one go.
            </p><p>
            Subclasses should override the <span class="nolink">[M:SendBuffer(LoggingEvent[])]</span>
            method to deliver the buffered events.
            </p><p>The BufferingAppenderSkeleton maintains a fixed size cyclic 
            buffer of events. The size of the buffer is set using 
            the <a href="P_log4net_Appender_BufferingAppenderSkeleton_BufferSize.htm">BufferSize</a> property.
            </p><p>A <a href="T_log4net_Core_ITriggeringEventEvaluator.htm">ITriggeringEventEvaluator</a> is used to inspect 
            each event as it arrives in the appender. If the <a href="P_log4net_Appender_BufferingAppenderSkeleton_Evaluator.htm">Evaluator</a> 
            triggers, then the current buffer is sent immediately 
            (see <span class="nolink">[M:SendBuffer(LoggingEvent[])]</span>). Otherwise the event 
            is stored in the buffer. For example, an evaluator can be used to 
            deliver the events immediately when an ERROR event arrives.
            </p><p>
            The buffering appender can be configured in a <a href="P_log4net_Appender_BufferingAppenderSkeleton_Lossy.htm">Lossy</a> mode. 
            By default the appender is NOT lossy. When the buffer is full all 
            the buffered events are sent with <span class="nolink">[M:SendBuffer(LoggingEvent[])]</span>.
            If the <a href="P_log4net_Appender_BufferingAppenderSkeleton_Lossy.htm">Lossy</a> property is set to <span class="code">true</span> then the 
            buffer will not be sent when it is full, and new events arriving 
            in the appender will overwrite the oldest event in the buffer. 
            In lossy mode the buffer will only be sent when the <a href="P_log4net_Appender_BufferingAppenderSkeleton_Evaluator.htm">Evaluator</a>
            triggers. This can be useful behavior when you need to know about 
            ERROR events but not about events with a lower level, configure an 
            evaluator that will trigger when an ERROR event arrives, the whole 
            buffer will be sent which gives a history of events leading up to
            the ERROR event.
