Description

Programmatic flush of BufferingAppenderSkeleton buffer

The BufferingAppenderSkeleton holds a buffer of events which are to be delivered to the appender subclass via the SendBuffer method. This buffer currently cannot be programmatically flushed to the appender.

It should be trivial to add support for a void Flush() method to the BufferingAppenderSkeleton class.

[Nicko Cadell]

Using this method it should be possible to write a simple method to flush all the appenders:


private static void FlushAllAppenders()
{
  foreach(log4net.Appender.IAppender appender in log4net.LogManager.GetRepository().GetAppenders())
  {
    log4net.Appender.BufferingAppenderSkeleton buffer = appender as log4net.Appender.BufferingAppenderSkeleton;
    if (buffer != null)
    {
      buffer.Flush();
    }
  }
}

Added public virtual void BufferingAppenderSkeleton.Flush() method.

This issue may be alleviated by the addition of a programmatic API for flushing the buffer held by the BufferingAppenderSkeleton. While this is not a general solution for all appenders and all types of output buffering I am going to leave this issue open.
