ValueRef
public struct ValueRef : 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 ValueRef
type acts as a lightweight Swift reference to an underlying GValue
instance.
It exposes methods that can operate on this data type through ValueProtocol
conformance.
Use ValueRef
only as an unowned
reference to an existing GValue
instance.
-
Untyped pointer to the underlying `GValue` instance.
For type-safe access, use the generated, typed pointer
value_ptr
property instead.Declaration
