Class AdvertiserMapperImpl

java.lang.Object

com.alpaca.mapper.impl.AdvertiserMapperImpl

All Implemented Interfaces:

GenericMapper<Advertiser,AdvertiserResponseDTO,AdvertiserRequestDTO>, IAdvertiserMapper

@Component
public class AdvertiserMapperImpl
extends Object
implements IAdvertiserMapper

Implementation of the IAdvertiserMapper interface, responsible for converting between Advertiser entities and their corresponding request and response DTOs.

This mapper relies on IUserService to resolve the associated User entity based on ID provided in the request DTO during conversion to an Advertiser entity.

Primary responsibilities:

• Convert a Advertiser entity into an AdvertiserResponseDTO.
• Construct an Advertiser entity from an AdvertiserRequestDTO, initializing default flags and resolving the associated User via IUserService.
• Transform collections of Advertiser entities into lists of AdvertiserResponseDTO.
• Handle null or empty inputs gracefully by returning null or empty lists respectively.

The class is annotated with Component for Spring integration, and leverages Lombok's RequiredArgsConstructor for constructor-based dependency injection.
