TypeClassRef

public struct TypeClassRef : TypeClassProtocol

The TypeClassRef type acts as a lightweight Swift reference to an underlying GTypeClass instance. It exposes methods that can operate on this data type through TypeClassProtocol conformance. Use TypeClassRef only as an unowned reference to an existing GTypeClass instance.

An opaque structure used as the base of all classes.

  • ptr
    Untyped pointer to the underlying `GTypeClass` instance.
    

    For type-safe access, use the generated, typed pointer _ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

TypeClass Record

  • Designated initialiser from the underlying C data type

    Declaration

    Swift

    @inlinable
    init(_ p: UnsafeMutablePointer<GTypeClass>)
  • Designated initialiser from a constant pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init(_ p: UnsafePointer<GTypeClass>)
  • Conditional initialiser from an optional pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init!(_ maybePointer: UnsafeMutablePointer<GTypeClass>?)
  • Conditional initialiser from an optional, non-mutable pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init!(_ maybePointer: UnsafePointer<GTypeClass>?)
  • Conditional initialiser from an optional gpointer

    Declaration

    Swift

    @inlinable
    init!(gpointer g: gpointer?)
  • Conditional initialiser from an optional, non-mutable gconstpointer

    Declaration

    Swift

    @inlinable
    init!(gconstpointer g: gconstpointer?)
  • Reference intialiser for a related type that implements TypeClassProtocol

    Declaration

    Swift

    @inlinable
    init<T>(_ other: T) where T : TypeClassProtocol
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(cPointer: UnsafeMutablePointer<T>)
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(constPointer: UnsafePointer<T>)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    init(mutating raw: UnsafeRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    init(raw: UnsafeMutableRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    init(opaquePointer: OpaquePointer)
  • This function is essentially the same as `g_type_class_ref()`,
    

    except that the classes reference count isn’t incremented. As a consequence, this function may return nil if the class of the type passed in does not currently exist (hasn’t been referenced before).

    Declaration

    Swift

    @inlinable
    static func peek(type: GType) -> TypeClassRef!
  • A more efficient version of g_type_class_peek() which works only for static types.

    Declaration

    Swift

    @inlinable
    static func peekStatic(type: GType) -> TypeClassRef!
  • Increments the reference count of the class structure belonging to type. This function will demand-create the class if it doesn’t exist already.

    Declaration

    Swift

    @inlinable
    static func ref(type: GType) -> TypeClassRef!
