Parameters

FarmAsset $asset: The farm_asset object to look for.

string $measure: The quantity measure to search for (ie: weight).

string $label: The quantity label to search for.

int $time: Unix timestamp limiter. Only logs before this time will be included. Defaults to the current time. Set to 0 to load the absolute last.

bool|null $done: Whether or not to only show logs that are marked as "done". TRUE will limit to logs that are done, and FALSE will limit to logs that are not done. If this is set to NULL, no filtering will be applied. Defaults to TRUE.
