Method Detail

  public com.google.common.base.Optional<T> fetch()

  Description copied from interface: FetchRequest
  Executes the request and returns the result, or absent if the object was not found.

• expand

  public FetchRequest<T> expand(java.lang.String... paths)

  Description copied from interface: FetchRequest
  Requests Reference fields to be expanded in the returned objects. Expanded references contain full target objects they link to.

  As an illustration, here is how reference expansion looks at the underlying JSON transport level. Given a customer object:

  {
    "name": "John Doe"
    "customerGroup": {
      "typeId": "customer-group",
      "id": "7ba61480-6a72-4a2a-a72e-cd39f75a7ef2"
    }
  }

  This is what the result looks like when the path 'customerGroup' has been expanded:

  {
    "name": "John Doe"
    "customerGroup": {
      typeId: "customer-group",
      id: "7ba61480-6a72-4a2a-a72e-cd39f75a7ef2"
      obj: {
        "name": "Gold"
      }
    }
  }

  Specified by:

  expand in interface FetchRequest<T>

  Parameters:

  paths - The paths to be expanded, such as 'customerGroup'.
