Internally, the request/response classes deal with encoding and decoding
BER values.
<p>
For example, suppose an LDAP server supports a "get time" extended operation.
It would supply classes such as
<code>GetTimeRequest</code> and <code>GetTimeResponse</code>,
so that applications can use this feature.
An application would use these classes as follows:
<blockquote><pre>
GetTimeResponse resp =
    (GetTimeResponse) ectx.extendedOperation(new GetTimeRequest());
long time = resp.getTime();
