RSDConditionalStepNavigatorObject

public struct RSDConditionalStepNavigatorObject : RSDConditionalStepNavigator, Decodable

RSDConditionalStepNavigatorObject is a concrete implementation of the RSDConditionalStepNavigator protocol.

  • An ordered list of steps to run for this task.

    Declaration

    Swift

    public let steps : [RSDStep]

  • A conditional rule to optionally associate with this step navigator.

    Declaration

    Swift

    public var conditionalRule : RSDConditionalRule?

  • A list of step markers to use for calculating progress.

    Declaration

    Swift

    public var progressMarkers : [String]?

  • Default initializer.

    Declaration

    Swift

    public init(with steps: [RSDStep])

    Parameters

    steps

    An ordered list of steps to run for this task.

  • Initialize from a Decoder. This decoding method will use the RSDFactory instance associated with the decoder to decode the steps and the conditionalRule.

  • example:

        let json = """
       {
           "progressMarkers": ["step1", "step2", "step3"],
           "steps": [
                      { "identifier" : "step1",
                        "type" : "instruction",
                        "title" : "Step 1" },
                      { "identifier" : "step2",
                        "type" : "instruction",
                        "title" : "Step 2" },
                      { "identifier" : "step2b",
                        "type" : "instruction",
                        "title" : "Step 2b" },
                      { "identifier" : "step3",
                        "type" : "instruction",
                        "title" : "Step 3" }
                    ],
           "conditionalRule" : {"type" : "medicationTracker"}
       }
       """.data(using: .utf8)! // our data in native (JSON) format

    • Throws

    DecodingError

    Declaration

    Swift

    public init(from decoder: Decoder) throws

    Parameters

    decoder

    The decoder to use to decode this instance.
