DESCRIPTION

51       "Net::LDAP::Control::Paged" provides an interface for the creation and
52       manipulation of objects that represent the "pagedResultsControl" as
53       described by RFC 2696.
54
55       The control is allowed on LDAP search requests ("search" in Net::LDAP)
56       only.  On other operations it will - depending on the value of the
57       parameter "critical" - either be ignored or lead to errors.
58

CONSTRUCTOR ARGUMENTS

60       In addition to the constructor arguments described in
61       Net::LDAP::Control the following are provided.
62
63       cookie
64           The value to use as the cookie. This is not normally set when an
65           object is created, but is set from the cookie value returned by the
66           server. This associates a search with a previous search, so the
67           server knows to return the page of entries following the entries it
68           returned the previous time.
69
70       size
71           The page size that is required. This is the maximum number of
72           entries that the server will return to the search request.
73

METHODS

75       As with Net::LDAP::Control each constructor argument described above is
76       also available as a method on the object which will return the current
77       value for the attribute if called without an argument, and set a new
78       value for the attribute if called with an argument.
