Class TypeMapper

  • All Implemented Interfaces:
    
public class TypeMapper

    Maps GraphQL types to Java types using ViaductSchema.TypeExpr. TypeExpr provides: - baseTypeDef: the base type (String, Int, User, etc.) - baseTypeNullable: is the base type nullable? - listDepth: depth of list nesting (0 = not a list, 1 = List, 2 = List

      • toJavaType

         String toJavaType(ViaductSchema.TypeExpr<out Object> typeExpr)

        Maps a ViaductSchema.TypeExpr to its Java representation.

        Parameters:
        typeExpr - the type expression
        Returns:

        the Java type string

      • toBoxedJavaType

         String toBoxedJavaType(ViaductSchema.TypeExpr<out Object> typeExpr)

        Maps a ViaductSchema.TypeExpr to its Java representation, always using boxed types for primitives. Use this when the type will appear as a generic type parameter (e.g., inside CompletableFuture or FieldResolverBase).

        Parameters:
        typeExpr - the type expression
        Returns:

        the boxed Java type string
