11

DESCRIPTION

23       "Net::LDAP::Control" is a base-class for LDAPv3 control objects.
24

CONSTRUCTORS

26       new ( ARGS )
27           ARGS is a list of name/value pairs, valid arguments are:
28
29           critical
30               A boolean value, if TRUE and the control is unrecognized by the
31               server or is inappropriate for the requested operation then the
32               server will return an error and the operation will not be
33               performed.
34
35               If FALSE and the control is unrecognized by the server or is
36               inappropriate for the requested operation then the server will
37               ignore the control and perform the requested operation as if
38               the control was not given.
39
40               If absent, FALSE is assumed.
41
42           type
43               A dotted-decimal representation of an OBJECT IDENTIFIER which
44               uniquely identifies the control. This prevents conflicts
45               between control names.
46
47               This may be ommitted if the contructor is being called on a
48               sub-class of Net::LDAP::Control which has registered to be
49               associated with an OID.  If the contructor is being called on
50               the Net::LDAP::Control package, then this argument must be
51               given.  If the given OID has been registered by a package, then
52               the returned object will be of the type registered to handle
53               that OID.
54
55           value
56               Optional information associated with the control. It's format
57               is specific to the particular control.
58
59       from_asn ( ASN )
60           ASN is a HASH reference, normally extracted from a PDU. It will
61           contain a "type" element and optionally "critical" and "value"
62           elements. On return ASN will be blessed into a package. If "type"
63           is a registered OID, then ASN will be blessed into the registered
64           package, if not then ASN will be blessed into Net::LDAP::Control.
65
66           This constructor is used internally by Net::LDAP and assumes that
67           HASH passed contains a valid control. It should be used with
68           caution.
69

METHODS

71       In addition to the methods listed below, each of the named parameters
72       to "new" is also avaliable as a method. "type" will return the OID of
73       the control object. "value" and "critical" are set/get methods and will
74       return the current value for each attribute if called without
75       arguments, but may also be called with arguments to set new values.
76
77       error ()
78           If there has been an error returns a description of the error,
79           otherwise it will return "undef"
80
81       init ()
82           "init" will be called as the last step in both contructors. What it
83           does will depend on the sub-class. It must always return the
84           object.
85
86       register ( OID )
87           "register" is provided for sub-class implementors. It should be
88           called as a class method on a sub-class of Net::LDAP::Control with
89           the OID that the class will handle. Net::LDAP::Control will
90           remember this class and OID pair and use it in the following
91           situations.
92
93           ·   "new" is called as a class method on the Net::LDAP::Control
94               package and OID is passed as the type. The returned object will
95               be blessed into the package that registered the OID.
96
97           ·   "new" is called as a class method on a registered package and
98               the "type" is not specified. The "type" will be set to the OID
99               registered by that package.
100
101           ·   "from_asn" is called to construct an object from ASN. The
102               returned object will be blessed into the package which was
103               registered to handle the OID in the ASN.
104
105       ( to_asn )
106           Returns a structure suitable for passing to Convert::ASN1 for
107           encoding. This method will be called by Net::LDAP when the control
108           is used.
109
110           The base class implementation of this method will call the "value"
111           method without arguments to allow a sub-class to encode it's value.
112           Sub-classes should not need to override this method.
113
114       valid ()
115           Returns true if the object is valid and can be encoded. The default
116           implementation for this method is to return TRUE if there is no
117           error, but sub-classes may override that.
