Project Modules

Main Classes

• Supplychain.CourierChain: Implements the main contract for managing parcels
• Supplychain.Parcel: Represents a parcel with various properties such as sender, receiver, and delivery status

Key Methods

• CourierChain.addParcel: Adds a new parcel to the ledger
• CourierChain.queryParcel: Queries a parcel by its ID
• CourierChain.updateParcelStatus: Updates the status of a parcel
• CourierChain.deliverParcel: Updates the delivery details of a parcel

Example Usage

// Adding a new parcel
CourierChain courierChain = new CourierChain();
courierChain.addParcel(ctx, "parcelId", "sender", "receiver", "from", "to", 
    "endDate", "charges", "modeOfDelivery", "deliveredBy", "parcelWeight", 
    "parcelWorth", "status");

// Querying a parcel
Parcel parcel = courierChain.queryParcel(ctx, "parcelId");

// Updating parcel status
courierChain.updateParcelStatus(ctx, "parcelId", "Delivered");

// Delivering a parcel
courierChain.deliverParcel(ctx, "parcelId", "deliveryHub");
