func ReachedFreezer

func ReachedFreezer(tag Tag, freezerSensorName string, trackingEPCs map[string]interface{}) bool

ReachedFreezer verifies if tag's current location is in freezerSensorName (destination) and it's a tracking epc

Types

type InventoryEvent

type InventoryEvent struct {
	Data []Tag `json:"data"`
}

InventoryEvent holds EdgeX events schema

type LocationHistory

type LocationHistory struct {
