Base class for any object that keeps a reference count. [Resource] and many other helper objects inherit this class.
2021-10-08 00:16:59 +00:00
Unlike other [Object] types, [RefCounted]s keep an internal reference counter so that they are automatically released when no longer in use, and only then. [RefCounted]s therefore do not need to be freed manually with [method Object.free].
2021-06-04 16:03:15 +00:00
In the vast majority of use cases, instantiating and using [RefCounted]-derived types is all you need to do. The methods provided in this class are only for advanced users, and can cause issues if misused.

[b]Note:[/b] In C#, reference-counted objects will not be freed instantly after they are no longer in use. Instead, garbage collection will run periodically and will free reference-counted objects that are no longer in use. This means that unused ones will linger on for a while before being removed.
