RSDComparableSurveyRuleObject

public struct RSDComparableSurveyRuleObject<T> : RSDComparableSurveyRule, Codable where T : Decodable, T : Encodable

RSDComparableSurveyRuleObject is a survey rule that matches an expected result to the answer and vends a skip identifier if the match is evaluated to true.

  • Optional skip identifier for this rule. If available, this will be used as the skip identifier, otherwise the skipToIdentifier will be assumed to be RSDIdentifier.exit

    Declaration

    Swift

    public let skipToIdentifier: String?

  • Optional cohort to assign if the rule matches. If available, then an RSDCohortRule can be used to track the cohort to assign depending upon how this rule evaluates.

    Declaration

    Swift

    public let cohort: String?

  • The rule operator to apply. If nil, .equal will be assumed unless the expectedAnswer is also nil, in which case .skip will be assumed.

    Declaration

    Swift

    public let ruleOperator: RSDSurveyRuleOperator?

  • Expected answer for the rule. If nil, then the operator must be .skip or this will return a nil value.

    Declaration

    Swift

    public var matchingAnswer: Any? { get }

  • Default initializer.

    Declaration

    Swift

    public init(skipToIdentifier: String?, matchingValue: Value?, ruleOperator: RSDSurveyRuleOperator?, cohort: String? = nil)

    Parameters

    skipToIdentifier

    Skip identifier for this rule.
    matchingValue

    Value-typed matching answer.
    ruleOperator

    The rule operator to apply.
    cohort

    The cohort to assign for this rule if it matches.

  • Initialize from a Decoder. This method will decode the values and also check that the combination of inputs is valid.

    Throws

    DecodingError if there is a decoding error.

    Declaration

    Swift

    public init(from decoder: Decoder) throws

    Parameters

    decoder

    The decoder to use to decode this instance.
