HistoryEntry<R extends FhirNode> class

One row of a resource's history: a version of the resource, or the tombstone a delete leaves (deleted, with no resource).

Constructors

HistoryEntry({required String resourceType, required String id, required String versionId, required DateTime lastUpdated, required bool deleted, required R? resource})

Creates one history entry.

const

HistoryEntry.fromRow(ResourcesHistoryData row, FhirModel<R, Object> model)

Reads one resources_history row. A tombstone is the row's own deleted flag (schema 13); its JSON is a skeleton with no content, so it is not parsed as the resource type. Any other row is the resource at that version. The tombstone JSON still carries the DELETED tag for a reader of the raw table, but a tag in a live resource no longer makes it read as deleted (fhirant REVIEW-2026-09-08 row 36).
