ParamSpecVariant
open class ParamSpecVariant : ParamSpec, ParamSpecVariantProtocol
A GParamSpec
derived structure that contains the meta data for GVariant
properties.
When comparing values with g_param_values_cmp()
, scalar values with the same
type will be compared with g_variant_compare()
. Other non-nil
variants will
be checked for equality with g_variant_equal()
, and their sort order is
otherwise undefined. nil
is ordered before non-nil
variants. Two nil
values compare equal.
The ParamSpecVariant
type acts as a reference-counted owner of an underlying GParamSpecVariant
instance.
It provides the methods that can operate on this data type through ParamSpecVariantProtocol
conformance.
Use ParamSpecVariant
as a strong reference or owner of a GParamSpecVariant
instance.
-
Designated initialiser from the underlying `C` data type.
This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the
ParamSpecVariant
instance.Declaration
Swift
@inlinable public init(_ op: UnsafeMutablePointer<GParamSpecVariant>)
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 theParamSpecVariant
instance.Declaration
Swift
@inlinable public init(_ op: UnsafePointer<GParamSpecVariant>)
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 theParamSpecVariant
instance.Declaration
Swift
@inlinable override 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 theParamSpecVariant
instance.Declaration
Swift
@inlinable override 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 theParamSpecVariant
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GParamSpecVariant>?)
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 theParamSpecVariant
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GParamSpecVariant>?)
Parameters
op
pointer to the underlying object
-
Designated initialiser from the underlying
C
data type. Will retainGParamSpecVariant
. i.e., ownership is transferred to theParamSpecVariant
instance.Declaration
Swift
@inlinable public init(retaining op: UnsafeMutablePointer<GParamSpecVariant>)
Parameters
op
pointer to the underlying object
-
Reference intialiser for a related type that implements
ParamSpecVariantProtocol
Will retainGParamSpecVariant
