type Ref = CFNumberRef
type Ref = CFNumberRef
The reference type wrapped inside this type.
Returns the object as its concrete TypeRef.
Returns an instance of the object, wrapping the underlying CFTypeRef
subclass. Use this
when following Core Foundation’s “Get Rule”. The reference count is bumped. Read more
Returns the object as a raw CFTypeRef
. The reference count is not adjusted.

when following Core Foundation’s “Create Rule”. The reference count is not bumped. Read more
Returns the object as a wrapped CFType
. The reference count is incremented by one.
Returns the object as a wrapped CFType
. Consumes self and avoids changing the reference
count. Read more
