GraphQLIntersectionType

Intersection Type Definition

When a field can return one of a set of types constrained by multiple abstract types, an Intersection type is used to describe the constraints as well as providing a function to determine which type is actually used when the field is resolved.

Example:

const PetNodeType = new GraphQLIntersectionType({
  name: 'Pet',
  types: [ PetType, NodeType ],
  resolveType(value) {
    if (value instanceof Dog) {
      return DogType;
    }
    if (value instanceof Cat) {
      return CatType;
    }
  }
});
