class XMPPError(Exception):
"""
A generic exception that may be raised while processing an XMPP stanza
to indicate that an error response stanza should be sent.
The exception method for stanza objects extending
:class:`~sleekxmpp.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 SleekXMPP plugins and applications using SleekXMPP.
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.
:param extension_args: Content and attributes for the extension
element. Same as the additional arguments to
the :class:`~xml.etree.ElementTree.Element`
constructor.
:param clear: Indicates if the stanza's contents should be
removed before replying with an error.
Defaults to ``True``.
