DeviceProtocol

public protocol DeviceProtocol

The DeviceProtocol protocol exposes the methods and properties of an underlying cairo_device_t instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Device. Alternatively, use DeviceRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • ptr

    Untyped pointer to the underlying cairo_device_t instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • _ptr Default implementation

    Typed pointer to the underlying cairo_device_t instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the cairo_device_t instance.

    Declaration

    Swift

    var _ptr: UnsafeMutablePointer<cairo_device_t>! { get }
  • Required Initialiser for types conforming to DeviceProtocol

    Declaration

    Swift

    init(raw: UnsafeMutableRawPointer)
