RSDStepTransformerObject

public struct RSDStepTransformerObject : RSDStepTransformer, Decodable

RSDStepTransformerObject is used in decoding a step with replacement properties for some or all of the steps in a section that is defined using a different resource. The factory will convert this step into an appropriate RSDSectionStep from the decoded object.

  • The transformed step.

    Declaration

    Swift

    public let transformedStep: RSDStep!

  • Initialize from a Decoder.

  • example:

        // Example JSON dictionary that includes a transformation step. The section is created from the
    // resource and then the values in the `replacementSteps` are used to mutate that step.
    let json = """
