DispatchSource.MemoryPressureEvent

description

getDescription($self: DispatchSource_MemoryPressureEvent): string

var description: String { get }

A textual representation of this instance. Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the `String(describing:)` initializer. This initializer works with any type, and uses the custom `description` property for types that conform to `CustomStringConvertible`: struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)" The conversion of `p` to a string in the assignment to `s` uses the `Point` type's `description` property.

init

init(rawValue: number): DispatchSource_MemoryPressureEvent

init(rawValue: UInt)

Creates a new option set from the given raw value. This initializer always succeeds, even if the value passed as `rawValue` exceeds the static properties declared as part of the option set. This example creates an instance of `ShippingOptions` with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members. let extraOptions = ShippingOptions(rawValue: 255) print(extraOptions.isStrictSuperset(of: .all)) // Prints "true" - Parameter rawValue: The raw value of the option set to create. Each bit of `rawValue` potentially represents an element of the option set, though raw values may include bits that are not defined as distinct values of the `OptionSet` type.

rawValue

getRawValue($self: DispatchSource_MemoryPressureEvent): number

let rawValue: UInt

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"
