data_events: Support for bulk tracking of data changesΒΆ
This module provides a singleton of class Tracker
,
tracker
,
that is used to batch notifications of changes of various data
structures.
Notifications are ordered, so the nofications for particular
data types will always be in the same order.
Data types that should be tracked are registered with
Tracker.register_data_type()
and the order given.
def computation():
from chimerax.core.data_events import tracker
with tracker:
# manipulate data
