  • Method Details

    • isValid

      boolean isValid()
      Whether the response is valid. A response is invalid in one of the following two cases:
      • the response map has no "data" entry indicating errors before execution, e.g. grammar parse and validation
      • the "data" entry has a null value indicating errors during execution that prevented a valid response

      A valid response has a "data" key with a non-null value, but it may still be partial and have some fields set to null due to field errors.

      For more details, see section 7 "Response" in the GraphQL spec.

    • getData

      @Nullable <T> T getData()
      Return the data part of the response, or null when the response is not valid.
      Type Parameters:
      T - a map or a list

    • getErrors

      List<ResponseError> getErrors()
      Return errors included in the response.

      A response that is not valid contains "request errors". Those are errors that apply to the request as a whole, and have an empty error path.

      A response that is valid may still be partial and contain "field errors". Those are errors associated with a specific field through their error path.

    • field

      ResponseField field(String path)
      Navigate to the given path under the "data" key of the response map where the path is a dot-separated string with optional array indexes.

      Example paths: 

       "hero"
 "hero.name"
 "hero.friends"
 "hero.friends[2]"
 "hero.friends[2].name"
      Parameters:
      path - relative to the "data" key
      Returns:
      representation for the field with further options to inspect or decode its value; use ResponseField.getValue() to check if the field actually has a value.

    • getExtensions

      Map<Object,Object> getExtensions()
      Return implementor specific, protocol extensions, if any.

    • toMap

      Map<String,Object> toMap()
      Return a map representation of the response, formatted as required in the "Response" section of the GraphQL spec.
