RSDComparableSurveyRuleObject

public struct RSDComparableSurveyRuleObject<T : Codable> : RSDComparableSurveyRule, Codable

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?

  • 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.

    public var matchingAnswer: Any?

  • Undocumented

    Declaration

    Swift

    public let matchingValue: Value?

  • Default initializer.
