to indicate that an error response stanza should be sent.
|
|
|
|
The exception method for stanza objects extending

|
:class:`~slixmpp.stanza.rootstanza.RootStanza` will create an error
|
|
stanza and initialize any additional substanzas using the extension
|
|
information included in the exception.
|
|
|
|
Meant for use in Slixmpp plugins and applications using Slixmpp.
|
|
|
|
Extension information can be included to add additional XML elements
|
|
to the generated error stanza.
|
|
|
|
:param condition: The XMPP defined error condition.
|
|
Defaults to ``'undefined-condition'``.
|
|
:param text: Human readable text describing the error.
|
|
:param etype: The XMPP error type, such as ``'cancel'`` or ``'modify'``.
|
|
Defaults to ``'cancel'``.

|
:param extension: Tag name of the extension's XML content.
|
|
:param extension_ns: XML namespace of the extensions' XML content.
|

|
|
removed before replying with an error.
