RSDAnswerResultType

public struct RSDAnswerResultType : Codable

RSDAnswerResultType is a Codable struct that can be used to describe how to encode and decode an RSDAnswerResult. It carries information about the type of the value and how to encode it. This struct serves a different purpose from the RSDFormDataType because it only carries information required to store a result and not additional information about presentation style.

RSDAnswerResult and RSDFormDataType

  • The base type of the answer result. This is used to indicate what the type is of the value being stored. The value stored in the RSDAnswerResult should be convertable to one of these base types.

    Declaration

    Swift

    public enum BaseType : String, Codable

  • The sequence type of the answer result. This is used to represent a multiple-choice answer array or a key/value dictionary.

    Declaration

    Swift

    public enum SequenceType : String, Codable

  • The base type for the answer.

    Declaration

    Swift

    public let baseType: BaseType

  • The sequence type (if any) for the answer.

    Declaration

    Swift

    public let sequenceType: SequenceType?

  • The original data type of the form input item.

    Declaration

    Swift

    public let formDataType: RSDFormDataType?

  • The date format that should be used to encode and decode the answer.

    Declaration

    Swift

    public let dateFormat: String?

  • The date formatter locale identifier that should be used to encode and decode the answer. If nil, the default Locale will be set to en_US_POSIX.

    Declaration

    Swift

    public var dateLocaleIdentifier: String?

  • The unit (if any) to store with the answer for localized measurement conversion.

    Declaration

    Swift

    public let unit: String?

  • A conveniece property for accessing the formatter used to encode and decode a date.

    Declaration

    Swift

    public var dateFormatter: DateFormatter?

  • The sequence separator to use when storing a multiple component answer as a string.

    For example, blood pressure might be represented using an array with two fields but is stored as a single string value of 120/90. In this case, / would be the separator.
