hap-nodejs/dist/lib/model/IdentifierCache.d.ts

HAP-NodeJS is a Node.js implementation of HomeKit Accessory Server.

import { MacAddress } from "../../types";
/**
 * IdentifierCache is a model class that manages a system of associating HAP "Accessory IDs" and "Instance IDs"
 * with other values that don't usually change. HomeKit Clients use Accessory/Instance IDs as a primary key of
 * sorts, so the IDs need to remain "stable". For instance, if you create a HomeKit "Scene" called "Leaving Home"
 * that sets your Alarm System's "Target Alarm State" Characteristic to "Arm Away", that Scene will store whatever
 * "Instance ID" it was given for the "Target Alarm State" Characteristic. If the ID changes later on this server,
 * the scene will stop working.
