NAME

6       AnyEvent::XMPP::Ext::DataForm - XEP-0004 DataForm
7

SYNOPSIS

DESCRIPTION
10       This module represents a Data Form as specified in XEP-0004.
11

METHODS
13       new (%args)
14       append_field ($field)
15           This method appends a field to the form.  $field must have the
16           structure as described in "FIELD STRUCTURE" below.
17
18       from_node ($node)
19           This method interprets the AnyEvent::XMPP::Node object in $node as
20           data form XML node and reads out the fields and all associated
21           information.
22
23           ($node must be the XML node of the <x xmlns='jabber:x:data'> tag).
24
25       make_answer_form ($request_form)
26           This method initializes this form with default answers and other
27           neccessary fields from $request_form, which must be of type
28           AnyEvent::XMPP::Ext::DataForm or compatible.
29
30           The result will be a form with a copy of all fields which are not
31           of type "fixed". The fields will also have the default value copied
32           over.
33
34           The form type will be set to "submit".
35
36           The idea is: this creates a template answer form from
37           $request_form.
38
39           To strip out the unneccessary fields later you don't need call the
40           "clear_empty_fields" method.
41
42       clear_empty_fields
43           This method removes all fields that have no values and options.
44
45       remove_field ($field_or_var)
46           This method removes a field either by it's unique name or by
47           reference. $field_or_var can either be the unique name or the
48           actual field hash reference you get from "get_field" or
49           "get_fields".
50
51       set_form_type ($type)
52           This method sets the type of the form, which must be one of:
53
54              form, submit, cancel, result
55
56       form_type
57           This method returns the type of the form, which is one of the
58           options described in "set_form_type" above or undef if no type was
59           yet set.
60
61       get_reported_fields
62           If this is a search result this method returns more than one
63           element here. The returned list consists of fields as described in
64           "FIELD STRUCTURE", only that they lack values and options.
65
66           See also the "get_items" method.
67
68       get_items
69           If this form is a search result this method returns the list of
70           items of that search.
71
72           An item is a array ref of fields (field structure is described in
73           "FIELD STRUCTURE").  This method returns a list of items.
74
75       get_fields
76           This method returns a list of fields. Each field has the structure
77           as described in "FIELD STRUCTURE".
78
79       get_field ($var)
80           Returns the field with the unique field name $var or undef if no
81           such field is in this form.
82
83       set_field_value ($var, $value)
84           This method sets the value of the field with the unique name $var.
85           If the field has supports multiple values all values will be
86           removed and only $value will be added, if $value is undefined the
87           field's value will be deleted.
88
89       add_field_value ($var, $value)
90           This method adds the $value to the field with the unique name $var.
91           If the field doesn't support multiple values this method has the
92           same effect as "set_field_value".
93
94       to_simxml
95           This method converts the form to a data strcuture that you can pass
96           as "node" argument to the "simxml" function which is documented in
97           AnyEvent::XMPP::Util.
98
99           Example call might be:
100
101              my $node = $form->to_simxml;
102              simxml ($w, defns => $node->{ns}, node => $node);
103
104           NOTE: The returned simxml node has the "dns" field set so that no
105           prefixes are generated for the namespace it is in.
106
107       as_debug_string
108           This method returns a string that represents the form.  Only for
109           debugging purposes.
