event handler
A callback function that responds to events raised by XMLStream.event().
stanza object

Informally may refer both to classes which extend ElementBase or StanzaBase, and to objects of such classes.

A stanza object is a wrapper for an XML object which exposes dict like interfaces which may be assigned to, read from, or deleted.

stanza plugin
A stanza object which has been registered as a potential child of another stanza object. The plugin stanza may accessed through the parent stanza using the plugin’s plugin_attrib as an interface.
stream handler
A callback function that accepts stanza objects pulled directly from the XML stream. A stream handler is encapsulated in a object that includes a Matcher object, and which provides additional semantics. For example, the Waiter handler wrapper blocks thread execution until a matching stanza is received.
