in.co.akshitbansal.springwebquery.resolver.field.DTOAwareFieldResolver

All Implemented Interfaces:

FieldResolver

public class DTOAwareFieldResolver
extends Object
implements FieldResolver

FieldResolver implementation that treats a DTO type as the public query contract and maps DTO selector paths to entity selector paths.

Resolution proceeds in three steps:

• Resolve the incoming path against the DTO class structure.
• Validate the terminal DTO field via the supplied callback.
• Translate the DTO path to an entity path using MapsTo, then verify that the resulting entity path exists.
