TypeClassRef
public struct TypeClassRef : TypeClassProtocol
An opaque structure used as the base of all classes.
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.
-
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

data typeDeclaration
Swift
@inlinable init(_ p: UnsafeMutablePointer<GTypeClass>)
-
Designated initialiser from a constant pointer to the underlying

data typeDeclaration
Swift
@inlinable init(_ p: UnsafePointer<GTypeClass>)
-
Conditional initialiser from an optional pointer to the underlying
C
data typeDeclaration
Swift
@inlinable init!(_ maybePointer: UnsafeMutablePointer<GTypeClass>?)
-
Conditional initialiser from an optional, non-mutable pointer to the underlying
C
data typeDeclaration
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) -> GLibObject.TypeClassRef!
-
A more efficient version of
g_type_class_peek()
which works only for static types.Declaration
Swift
@inlinable static func peekStatic(type: GType) -> GLibObject.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) -> GLibObject.TypeClassRef!
