Public Overridable Sub Flush ()
This default method does nothing, but derived classes can override the method to provide the appropriate functionality.
Flushing the stream will not flush its underlying encoder unless you explicitly call
Flush or Close. Setting AutoFlush to
true means that data will be flushed from the buffer to the stream, but the encoder state will not be flushed. This allows the encoder to keep its state (partial characters) so that it can encode the next block of characters correctly. This scenario affects UTF8 and UTF7 where certain characters can only be encoded after the encoder receives the adjacent character or characters.
