Example 6 with ASN1StreamReader

/**
 * Creates a new LDAP result object with the provided message ID and with the

 *
 * @param  messageID        The LDAP message ID for the LDAP message that is
 *                          associated with this LDAP result.
 * @param  messageSequence  The ASN.1 stream reader sequence used in the
 *                          course of reading the LDAP message elements.
 * @param  reader           The ASN.1 stream reader from which to read the
 *                          protocol op and controls.
 *
 * @return  The decoded LDAP result.
 *
 * @throws  LDAPException  If a problem occurs while reading or decoding data
 *                         from the ASN.1 stream reader.
