Each operator has an attached Python "storage" dictionary. Values stored in this dictionary are persistent, and saved with the operator. The storage dictionary contents may be manipulated directly with methods such as
OP.store() described below, or examined with an Examine DAT.
When an immutable element of storage changes, expressions that depend on it will automatically cook. For information about cooking of mutable elements (lists, dicts, sets), see deeply dependable collections.
Preserving in Files
Storage is saved with
.tox files and loaded on startup.
