6 Net::XMPP::IQ - XMPP Info/Query Module
7
9 Net::XMPP::IQ is a companion to the Net::XMPP module. It
10 provides the user a simple interface to set and retrieve all
11 parts of an XMPP IQ.
12
14 Net::XMPP::IQ differs from the other Net::XMPP::* modules in that
15 the XMLNS of the query is split out into a submodule under
16 IQ. For specifics on each module please view the documentation
17 for the Net::XMPP::Namespaces module.
18 A Net::XMPP::IQ object is passed to the callback function for the
20 message. Also, the first argument to the callback functions is the
21 session ID from XML::Stream. There are some cases where you might
22 want this information, like if you created a Client that connects to
23 two servers at once, or for writing a mini server.
24 use Net::XMPP;
26 sub iq {
28 my ($sid,$IQ) = @_;
29 .
30 .
31 my $reply = $IQ->Reply();
32 my $replyQuery->GetQuery();
33 .
34 }
35 You now have access to all of the retrieval functions available.
37 To create a new iq to send to the server:
39 use Net::XMPP;
41 $IQ = Net::XMPP::IQ->new();
43 $IQType = $IQ->NewChild( type );
44 $IQType->SetXXXXX("yyyyy");
45 Now you can call the creation functions for the IQ, and for the
47 <query/> on the new query object itself. See below for the <iq/>
48 functions, and in each query module for those functions.
49
51 General functions
52 Reply(%args) - Creates a return <iq/> with the to and from
53 filled in correctly, and a query object already
54 added in. The %args that you pass are passed
55 to SetIQ() and will overwrite the IQ settings
56 that Reply sets.
57 Retrieval functions
59 GetTo() - returns either a string with the JID, or a
60 GetTo("jid") Net::XMPP::JID object for the person who is
61 going to receive the <iq/>. To get the JID
62 object set the string to "jid", otherwise leave
63 blank for the text string.
64 $to = $IQ->GetTo();
66 $toJID = $IQ->GetTo("jid");
67 GetFrom() - returns either a string with the JID, or a
69 GetFrom("jid") Net::XMPP::JID object for the person who
70 sent the <iq/>. To get the JID object set
71 the string to "jid", otherwise leave blank for the
72 text string.
73 $from = $IQ->GetFrom();
75 $fromJID = $IQ->GetFrom("jid");
76 GetType() - returns a string with the type <iq/> this is.
78 $type = $IQ->GetType();
80 GetID() - returns an integer with the id of the <iq/>.
82 $id = $IQ->GetID();
84 GetError() - returns a string with the text description of the error.
86 $error = $IQ->GetError();
88 GetErrorCode() - returns a string with the code of error.
90 $errorCode = $IQ->GetErrorCode();
92 GetQuery() - returns a Net::XMPP::Stanza object that contains the data
94 in the query of the <iq/>. Basically, it returns the
95 first child in the <iq/>.
96 $query = $IQ->GetQuery();
98 GetQueryXMLNS() - returns a string with the namespace of the query
100 for this <iq/>, if one exists.
101 $xmlns = $IQ->GetQueryXMLNS();
103 Creation functions
105 SetIQ(to=>string|JID, - set multiple fields in the <iq/> at one
106 from=>string|JID, time. This is a cumulative and over
107 id=>string, writing action. If you set the "to"
108 type=>string, attribute twice, the second setting is
109 errorcode=>string, what is used. If you set the status, and
110 error=>string) then set the priority then both will be in
111 the <iq/> tag. For valid settings read the
112 specific Set functions below.
113 $IQ->SetIQ(type=>"get",
115 to=>"bob\@jabber.org");
116 $IQ->SetIQ(to=>"bob\@jabber.org",
118 errorcode=>403,
119 error=>"Permission Denied");
120 SetTo(string) - sets the to attribute. You can either pass a string
122 SetTo(JID) or a JID object. They must be a valid Jabber
123 Identifiers or the server will return an error message.
124 (ie. bob@jabber.org, etc...)
125 $IQ->SetTo("bob\@jabber.org");
127 SetFrom(string) - sets the from attribute. You can either pass a
129 SetFrom(JID) string or a JID object. They must be a valid JIDs
130 or the server will return an error message.
131 (ie. bob@jabber.org, etc...)
132 $IQ->SetFrom("me\@jabber.org");
134 SetType(string) - sets the type attribute. Valid settings are:
136 get request information
138 set set information
139 result results of a get
140 error there was an error
141 $IQ->SetType("set");
143 SetErrorCode(string) - sets the error code of the <iq/>.
145 $IQ->SetErrorCode(403);
147 SetError(string) - sets the error string of the <iq/>.
149 $IQ->SetError("Permission Denied");
151 NewChild(string) - creates a new Net::XMPP::Stanza object with the
153 namespace in the string. In order for this
154 function to work with a custom namespace, you
155 must define and register that namespace with the
156 IQ module. For more information please read the
157 documentation for Net::XMPP::Stanza.
158 $queryObj = $IQ->NewChild("jabber:iq:auth");
160 $queryObj = $IQ->NewChild("jabber:iq:roster");
161 Reply(hash) - creates a new IQ object and populates the to/from
163 fields. If you specify a hash the same as with SetIQ
164 then those values will override the Reply values.
165 $iqReply = $IQ->Reply();
167 $iqReply = $IQ->Reply(type=>"result");
168 Removal functions
170 RemoveTo() - removes the to attribute from the <iq/>.
171 $IQ->RemoveTo();
173 RemoveFrom() - removes the from attribute from the <iq/>.
175 $IQ->RemoveFrom();
177 RemoveID() - removes the id attribute from the <iq/>.
179 $IQ->RemoveID();
181 RemoveType() - removes the type attribute from the <iq/>.
183 $IQ->RemoveType();
185 RemoveError() - removes the <error/> element from the <iq/>.
187 $IQ->RemoveError();
189 RemoveErrorCode() - removes the code attribute from the <error/>
191 element in the <iq/>.
192 $IQ->RemoveErrorCode();
194 Test functions
196 DefinedTo() - returns 1 if the to attribute is defined in the <iq/>,
197 0 otherwise.
198 $test = $IQ->DefinedTo();
200 DefinedFrom() - returns 1 if the from attribute is defined in the
202 <iq/>, 0 otherwise.
203 $test = $IQ->DefinedFrom();
205 DefinedID() - returns 1 if the id attribute is defined in the <iq/>,
207 0 otherwise.
208 $test = $IQ->DefinedID();
210 DefinedType() - returns 1 if the type attribute is defined in the
212 <iq/>, 0 otherwise.
213 $test = $IQ->DefinedType();
215 DefinedError() - returns 1 if <error/> is defined in the <iq/>,
217 0 otherwise.
218 $test = $IQ->DefinedError();
220 DefinedErrorCode() - returns 1 if the code attribute is defined in
222 <error/>, 0 otherwise.
223 $test = $IQ->DefinedErrorCode();
225 DefinedQuery() - returns 1 if there is at least one namespaced
227 child in the object.
