24 | =head1 NAME |
---|
25 | |
---|
26 | Net::XMPP::Stanza - XMPP Stanza Module |
---|
27 | |
---|
28 | =head1 SYNOPSIS |
---|
29 | |
---|
30 | Net::XMPP::Stanza is a private package that serves as a basis for all |
---|
31 | XMPP stanzas generated by Net::XMPP. |
---|
32 | |
---|
33 | =head1 DESCRIPTION |
---|
34 | |
---|
35 | This module is not meant to be used directly. You should be using |
---|
36 | either Net::XMPP::IQ, Net::XMPP::Message, Net::XMPP::Presence, or |
---|
37 | another package that inherits from Net::XMPP::Stanza. |
---|
38 | |
---|
39 | That said, this is where all of the namespaced methods are documented. |
---|
40 | |
---|
41 | The current supported namespaces are: |
---|
42 | |
---|
43 | =cut |
---|
44 | |
---|
45 | # NS_BEGIN |
---|
46 | |
---|
47 | =pod |
---|

---|

---|
51 | jabber:iq:register |
---|
52 | jabber:iq:roster |
---|
53 | urn:ietf:params:xml:ns:xmpp-bind |
---|
54 | urn:ietf:params:xml:ns:xmpp-session |
---|
55 | |
---|
56 | =cut |
---|
57 | |
---|
58 | # NS_END |
---|
59 | |
---|
60 | =pod |
---|
61 | |
---|
62 | For more information on what these namespaces are for, visit |
---|
63 | http://www.jabber.org and browse the Jabber Programmers Guide. |
---|
64 | |
---|
65 | The following tables can be read as follows: |
---|
66 | |
---|
67 | ny:private:ns |
---|
68 | |
---|

---|
71 | Foo scalar X X X X |
---|
72 | Bar child X |
---|
73 | Bars child X |
---|
74 | Test master X X |
---|
75 | |
---|
76 | Withing the my:private:ns namespace, there exists the functions: |
---|
77 | |
---|
78 | GetFoo(), SetFoo(), RemoveFoo(), DefinedFoo() |
---|
79 | |
---|
80 | AddBar() |
---|
81 | |
---|
82 | GetBars(), DefinedBars() |
---|
83 | |
---|
84 | GetTest(), SetMaster() |
---|
85 | |
---|
86 | Hopefully it should be obvious how this all works. If not feel free to |
---|
87 | contact me and I'll work on adding more documentation. |
