TypeClass

open class TypeClass : TypeClassProtocol

An opaque structure used as the base of all classes.

The TypeClass type acts as an owner of an underlying GTypeClass instance. It provides the methods that can operate on this data type through TypeClassProtocol conformance. Use TypeClass as a strong reference or owner of a GTypeClass instance.

  • 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!
  • Designated initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init(_ op: UnsafeMutablePointer<GTypeClass>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init(_ op: UnsafePointer<GTypeClass>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafePointer<GTypeClass>?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafeMutablePointer<GTypeClass>?)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. GTypeClass does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to the TypeClass instance.

    Declaration

    Swift

    @inlinable
    public init(retaining op: UnsafeMutablePointer<GTypeClass>)

    Parameters

    op

    pointer to the underlying object

  • Reference intialiser for a related type that implements TypeClassProtocol GTypeClass does not allow reference counting.

    Declaration

    Swift

    @inlinable
    public init<T>(_ other: T) where T : TypeClassProtocol

    Parameters

    other

    an instance of a related type that implements TypeClassProtocol

  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init<T>(cPointer p: UnsafeMutablePointer<T>)

    Parameters

    cPointer

    pointer to the underlying object

  • Unsafe typed, retaining initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init<T>(retainingCPointer cPointer: UnsafeMutablePointer<T>)

    Parameters

    cPointer

    pointer to the underlying object

  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init(raw p: UnsafeRawPointer)

    Parameters

    p

    raw pointer to the underlying object

  • Unsafe untyped, retaining initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init(retainingRaw 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
    public required init(raw p: UnsafeMutableRawPointer)

    Parameters

    p

    mutable raw pointer to the underlying object

  • Unsafe untyped, retaining initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init(retainingRaw raw: UnsafeMutableRawPointer)

    Parameters

    raw

    mutable raw pointer to the underlying object

  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init(opaquePointer p: OpaquePointer)

    Parameters

    p

    opaque pointer to the underlying object

  • Unsafe untyped, retaining initialiser. Do not use unless you know the underlying data type the pointer points to conforms to TypeClassProtocol.

    Declaration

    Swift

    @inlinable
    public init(retainingOpaquePointer p: OpaquePointer)

    Parameters

    p

    opaque pointer to the underlying object

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

    Declaration

    Swift

    @inlinable
    public static func peekStatic(type: GType) -> GLibObject.TypeClass!
  • 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
    public static func ref(type: GType) -> GLibObject.TypeClass!
