|---|
| 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 |

|---|
| 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: |

|---|
| 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() |

|---|
| 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. |
