Class AdapterKey<From,To>

java.lang.Object
com.guinetik.hexafun.hexa.AdapterKey<From,To>
Type Parameters:
From - The source type to adapt from
To - The target type to adapt to
public final class AdapterKey<From,To> extends Object
Type-safe key for adapter registration and invocation. Provides compile-time type checking for transformations between types.

Adapters transform data from one type to another, useful for:

  • Converting between use case input types
  • Mapping domain objects to DTOs
  • Transforming external data to internal representations

Usage: 


 // Define keys as constants
 public interface OrderAdapters {
     AdapterKey<OrderRequest, InventoryCheck> TO_INVENTORY =
         AdapterKey.of("orderToInventory");
     AdapterKey<OrderRequest, PaymentRequest> TO_PAYMENT =
         AdapterKey.of("orderToPayment");
 }

 // Register in DSL
 HexaFun.dsl()
     .withAdapter(TO_INVENTORY, req -> new InventoryCheck(req.itemId()))
     .withAdapter(TO_PAYMENT, req -> new PaymentRequest(req.total()))
     .useCase(...)
     .build();

 // Type-safe adaptation
 InventoryCheck check = app.adapt(TO_INVENTORY, orderRequest);
