init

TypeScript

init(rawValue: string): (Schema_Relationship_DeleteRule) | null

Swift declaration

init?(rawValue: String)

Creates a new instance with the specified raw value. If there is no value of the type that corresponds with the specified raw value, this initializer returns `nil`. For example: enum PaperSize: String { case A4, A5, Letter, Legal } print(PaperSize(rawValue: "Legal")) // Prints "Optional(PaperSize.Legal)" print(PaperSize(rawValue: "Tabloid")) // Prints "nil" - Parameter rawValue: The raw value to use for the new instance.

rawValue

TypeScript

getRawValue($self: Schema_Relationship_DeleteRule): string

Swift declaration

var rawValue: String { get }

The corresponding value of the raw type. A new instance initialized with `rawValue` will be equivalent to this instance. For example: enum PaperSize: String { case A4, A5, Letter, Legal } let selectedSize = PaperSize.Letter print(selectedSize.rawValue) // Prints "Letter" print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!) // Prints "true"
