graphql-java: Can an object definition be both a GraphQLObjectType & GraphQLInputObjectType

Question

I'm using graphql-java. I have customized object, e.g.: MyObject (which has some fields...).

The request is that i want to use it as a Parameter in another mutation object. And i don't want to define it twice (GraphQLObjectType & GraphQLInputObjectType).

Could it be done and how to do it? thanks

• GraphQLObjectType

  public GraphQLObjectType myObjectType() {
      return newObject()
              .name("MyObj")
              .description("My object")
  
              .field(newFieldDefinition()
                      .name("field1")
                      .description("field 1")
                      .type(GraphQLString))
              // ...
              .build();
  }
  

• GraphQLInputObjectType

  public GraphQLInputObjectType myInputObjectType() {
      return newInputObject()
          .name("MyInputObj")
          .description("My input object")
  
          .field(newInputObjectField()
                  .name("field1")
                  .description("field 1")
                  .type(GraphQLString))
          // ...
          .build();
      }

No, they're quite different things, and you'll usually find your input types diverge from the equivalent object types anyway. I'd rely on other patterns for code-reuse instead.
