Extends java.lang.Object This class provides a data structure for representing an LDAP search result reference. A search
result reference consists of a set of referral URLs and may also include zero or more controls. It
describes an alternate location in which additional results for the search may be found. If there are
multiple referral URLs, then they should all be considered equivalent ways to access the information
(e.g., referrals referencing different servers that may be contacted).
