33 "Net::LDAP::Control::PostRead" provides an interface for the creation
34 and manipulation of objects that represent the "Post-Read Controls" as
35 described by RFC 4527.
36
37 In modification operations, the "Post-Read request control" indicates
38 to the server that a copy of the modified entry after the update is to
39 be returned. After the successful completion of the operation, the
40 accompanying "Post-Read response control" allows one to retrieve the
41 updated value from the server's response.
42
43 One use case of this control may be to obtain values of operational
44 attributes, such as the "entryUUID" and "modifyTimestamp" attributes,
45 updated by the server as part of the update operation.
46
48 In addition to the constructor arguments described in
49 Net::LDAP::Control the following are provided.
50
51 attrs => [ ATTR, ... ]
52 A list of attributes to be returned in the entry returned in the
53 response control.
54
55 If absent, all attributes are returned.
56
57 Operational attributes may be included in the list by explicitly
58 asking for them or by using special "+" feature (provided the
59 server supports this feature).
60
62 As with Net::LDAP::Control each constructor argument described above is
63 also available as a method on the object which will return the current
64 value for the attribute if called without an argument, and set a new
65 value for the attribute if called with an argument.
66
67 In addition to these methods, the control also supports the following
68 method:
69
70 entry ()
71 Returns the entry from the response control in the response message
72 to the LDAP request that contained the request control.
73
74 The result is either a Net::LDAP::Entry object or undefined.
