liveFields method

@override Future<Map<String, Object?>> liveFields(String table, String prefix)

Returns all live (non-tombstoned) records in table whose key starts with prefix, as a flat map of key → value.

Pass an empty prefix to scan the full table (used by Collection.all and Collection.all). Pass a document-id prefix (e.g. "$id\x1F") to narrow the read to a single document's field records — a disk-backed adapter can use this to avoid loading the whole table.

Implementation

@override
Future<Map<String, Object?>> liveFields(String table, String prefix) {
  final map = _crdt.getMap(table);
  if (prefix.isEmpty) return Future.value(Map.of(map));
  return Future.value({
    for (final e in map.entries)
      if (e.key.startsWith(prefix)) e.key: e.value,
  });
}
