<DL>
<DD>Clear the contents of the buffer. If the buffer has been already
 been flushed then the clear operation shall throw an IOException
 to signal the fact that some data has already been irrevocably 
 written to the client response stream.

clearBuffer</H3>
<PRE>
public abstract void <B>clearBuffer</B>()
                          throws java.io.IOException</PRE>
<DL>
<DD>Clears the current contents of the buffer. Unlike clear(), this
 method will not throw an IOException if the buffer has already been
 flushed. It merely clears the current content of the buffer and
 returns.

flush</H3>
<PRE>
public abstract void <B>flush</B>()
                    throws java.io.IOException</PRE>
<DL>
<DD>Flush the stream.  If the stream has saved any characters from the
 various write() methods in a buffer, write them immediately to their
 intended destination.  Then, if that destination is another character or
 byte stream, flush it.  Thus one flush() invocation will flush all the
 buffers in a chain of Writers and OutputStreams.
 <p>
 The method may be invoked indirectly if the buffer size is exceeded.
 <p>
 Once a stream has been closed,
 further write() or flush() invocations will cause an IOException to be
 thrown.

close</H3>
<PRE>
public abstract void <B>close</B>()
                    throws java.io.IOException</PRE>
<DL>
<DD>Close the stream, flushing it first.
 <p>
 This method needs not be invoked explicitly for the initial JspWriter
 as the code generated by the JSP container will automatically
 include a call to close().
 <p>
 Closing a previously-closed stream, unlike flush(), has no effect.
