metadata property

Map<String, Object?> metadata
final

Application-defined metadata, usable for filtering during search.

Documents returned from InMemoryVectorStore expose an unmodifiable copy of the map that was stored: a fresh top-level map, so mutating the map you passed in afterwards does not reach the store, and mutating the map you get back throws instead of silently rewriting the stored document.

Implementation

final Map<String, Object?> metadata;
