TypeClass

open class TypeClass : TypeClassProtocol

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.

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!
  • 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 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) -> 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) -> 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) -> TypeClass!
