<PRE>
void <B>setBufferSize</B>(int&nbsp;size)</PRE>
<DL>
<DD>Sets the preferred buffer size for the body of the response. The portlet
 container will use a buffer at least as large as the size requested.
 <p>
 This method must be called before any response body content is written;
 if content has been written, or the portlet container does not support
 buffering, this method may throw an <code>IllegalStateException</code>.
