Parameters

string $workspace_id: The ID of the workspace.

string $entity_type_id: An entity type ID to find revisions for.

int[]|string[]|null $entity_ids: (optional) An array of entity IDs to filter the results by. Defaults to NULL.

Return value

array Returns an array where the values are an array of entity IDs keyed by revision IDs.
