ParamSpecVariant

open class ParamSpecVariant : ParamSpec, ParamSpecVariantProtocol

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.

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.

  • 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

    public init(_ op: UnsafeMutablePointer<GParamSpecVariant>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. Will retain GParamSpecVariant. i.e., ownership is transferred to the ParamSpecVariant instance.

    Declaration

    Swift

    public init(retaining op: UnsafeMutablePointer<GParamSpecVariant>)

    Parameters

    op

    pointer to the underlying object

  • Reference intialiser for a related type that implements ParamSpecVariantProtocol Will retain GParamSpecVariant.

    Declaration

    Swift

    public init<T>(paramSpecVariant other: T) where T : ParamSpecVariantProtocol

    Parameters

    other

    an instance of a related type that implements ParamSpecVariantProtocol

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

    Declaration

    Swift

    override 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 ParamSpecVariantProtocol.

    Declaration

    Swift

    override 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 ParamSpecVariantProtocol.

    Declaration

    Swift

    override 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 ParamSpecVariantProtocol.

    Declaration

    Swift

    override public init(retainingRaw raw: UnsafeRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to ParamSpecVariantProtocol.
