Définition

class InstrumentationEvents(Events):

Description _{[extrait de InstrumentationEvents.doc]}

Events related to class instrumentation events.

    The listeners here support being established against
    any new style class, that is any object that is a subclass
    of 'type'.  Events will then be fired off for events
    against that class.  If the "propagate=True" flag is passed
    to event.listen(), the event will fire off for subclasses
    of that class as well.

    The Python ``type`` builtin is also accepted as a target,
    which when used has the effect of events being emitted
    for all classes.

    Note the "propagate" flag here is defaulted to ``True``,
    unlike the other class level events where it defaults
    to ``False``.  This means that new subclasses will also
    be the subject of these events, when a listener
    is established on a superclass.
