Annotation Interface DefaultValue

@Target({PARAMETER,FIELD,METHOD})
@Retention(RUNTIME)
@Documented
public @interface DefaultValue

Controls the mapping of a method's parameter to an argument of a GraphQL operation (query/mutation/subscription).

For example, a user might annotate a method's parameter as such:

 public class CharacterService {
     @Query("searchByName"),
     public List<Character> getByName(
                       @Name("name")
                       @DefaultValue("Han Solo")
                       String name) {
         //...
     }
 }
 

Schema generation of this would result in a stanza such as:

 type Query {
     searchByName(name: String = "Han Solo"): [Character]
 }
