ValueBase
open class ValueBase : ValueProtocol
An opaque structure used to hold different types of values.
The data within the structure has protected scope: it is accessible only
to functions within a GTypeValueTable
structure, or implementations of
the g_value_*() API. That is, code portions which implement new fundamental
types.
GValue
users cannot make any assumptions about how data is stored
within the 2 element data
union, and the g_type
member should
only be accessed through the G_VALUE_TYPE()
macro.
The Value
type acts as an owner of an underlying GValue
instance.
It provides the methods that can operate on this data type through ValueProtocol
conformance.
Use Value
as a strong reference or owner of a GValue
instance.
-
Untyped pointer to the underlying `GValue` instance.
For type-safe access, use the generated, typed pointer
value_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 theValue
instance.Declaration
Swift
@inlinable public init(_ op: UnsafeMutablePointer<GValue>)
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 theValue
instance.Declaration
Swift
@inlinable public init(_ op: UnsafePointer<GValue>)
Parameters
op
pointer to the underlying object
-
Optional initialiser from a non-mutating
gpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theValue
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 underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theValue
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 theValue
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GValue>?)
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 theValue
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GValue>?)
Parameters
op
pointer to the underlying object
-
Designated initialiser from the underlying
C
data type.GValue
does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to theValue
instance.Declaration
Swift
@inlinable public init(retaining op: UnsafeMutablePointer<GValue>)
Parameters
op
pointer to the underlying object
-
Reference intialiser for a related type that implements
ValueProtocol
GValue
does not allow reference counting.Declaration
Swift
@inlinable public init<T>(_ other: T) where T : ValueProtocol
Parameters
other
an instance of a related type that implements
ValueProtocol
