/**
* This interface represents an LDAP extended operation response as defined in
* <A HREF="http://www.ietf.org/rfc/rfc2251.txt">RFC 2251.
* <pre>
* ExtendedResponse ::= [APPLICATION 24] SEQUENCE {
* COMPONENTS OF LDAPResult,
* responseName [10] LDAPOID OPTIONAL,
* response [11] OCTET STRING OPTIONAL }
* </pre>
* It comprises an optional object identifier and an optional ASN.1 BER
* encoded value.
*
*<p>
* The methods in this class can be used by the application to get low
* level information about the extended operation response. However, typically,
* the application will be using methods specific to the class that
* implements this interface. Such a class should have decoded the BER buffer
* in the response and should provide methods that allow the user to
* access that data in the response in a type-safe and friendly manner.
*<p>
* For example, suppose the LDAP server supported a 'get time' extended operation.
* It would supply GetTimeRequest and GetTimeResponse classes.
* The GetTimeResponse class might look like:
*<blockquote> * public class GetTimeResponse implements ExtendedResponse {
* public java.util.Date getDate() {...};
* public long getTime() {...};
* ....
* }
*</pre>
* A program would use then these classes as follows:
*<blockquote> * GetTimeResponse resp =
* (GetTimeResponse) ectx.extendedOperation(new GetTimeRequest());
* java.util.Date now = resp.getDate();
*</pre>
