Properties
This introspector returns True if a property's dependency is known. If it isn't, then properties containing the expression can't be fingerprinted, an optimization that exempts expressions from re-evaluation if their dependencies haven't changed.
- Q: (it as string, dependency known of it) of properties of type "file"
- A: json of <file>: json value, True
- A: sqlite database of <file>: sqlite database, False
- A: content of <file>: file content, True
- A: ...
