  # Objects like 'product' are a complex structure with fields
  # and their return type is not present.
  #
  # However, we also handle objects that have simple built-in types,
  # like 'current_tags', which is an 'array'. So, we follow them until
  # the source type:
  while object&.return_type
    generic_type = generic_type(object) if generic_type?(object)

#generic_type(object) ⇒ Object

Currently, we’re handling generic types only for arrays, so we get the array type

def generic_type(object)
  object.array_type
end

#generic_type?(object) ⇒ Boolean

Currently, we’re handling generic types only for arrays, so we check if it’s an array type

Returns:

  • (Boolean)
