If a stanza handler raised an exception, the exception was processed and replied by the modified stanza, not a stanza with the original content. A copy is now made before handler processing, and if an exception occurs it is the copy that processes the exception using the original content.

|
|
XMPP's <message> stanzas are a "push" mechanism to send information
|
|
to other XMPP entities without requiring a response.
|
|
|
|
Chat clients will typically use <message> stanzas that have a type
|
|
of either "chat" or "groupchat".
|
|
|
|
When handling a message event, be sure to check if the message is
|
|
an error response.
|
|
|
|
Example <message> stanzas:
|
|
<message to="user1@example.com" from="user2@example.com">
|
|
<body>Hi!</body>
|
|
</message>
|
|
|
|
<message type="groupchat" to="room@conference.example.com">
|
|
<body>Hi everyone!</body>
|
|
</message>
|
|
|
|
Stanza Interface:
|
|
body -- The main contents of the message.
|
|
subject -- An optional description of the message's contents.
|
|
mucroom -- (Read-only) The name of the MUC room that sent the message.
|
|
mucnick -- (Read-only) The MUC nickname of message's sender.
|
|
|
|
Attributes:
|
|
types -- May be one of: normal, chat, headline, groupchat, or error.
|
|
|
|
Methods:
|
|
setup -- Overrides StanzaBase.setup.
|
|
chat -- Set the message type to 'chat'.
|
|
normal -- Set the message type to 'normal'.
|
|
reply -- Overrides StanzaBase.reply
|
|
get_type -- Overrides StanzaBase interface
|
|
get_mucroom -- Return the name of the MUC room of the message.
|
|
set_mucroom -- Dummy method to prevent assignment.
|
|
del_mucroom -- Dummy method to prevent deletion.
|
|
get_mucnick -- Return the MUC nickname of the message's sender.
|
|
set_mucnick -- Dummy method to prevent assignment.
|
|
del_mucnick -- Dummy method to prevent deletion.
