ValueBase

open class ValueBase : ValueProtocol

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.

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.

  • ptr
    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 the Value instance.

    Declaration

    Swift

    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 the Value instance.

    Declaration

    Swift

    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

    public init<T>(_ other: T) where T : ValueProtocol

    Parameters

    other

    an instance of a related type that implements ValueProtocol

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

    Declaration

    Swift

    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 ValueProtocol.

    Declaration

    Swift

    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 ValueProtocol.

    Declaration

    Swift

    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 ValueProtocol.

    Declaration

    Swift

    public init(retainingRaw raw: UnsafeRawPointer)
