This makes it easier to spot syntax errors when editing the class reference. The schema is referenced locally so validation can still work offline. Each class XML's schema conformance is also checked on GitHub Actions.

Base class for reference-counted objects.

<description>
|
|
Base class for any object that keeps a reference count. [Resource] and many other helper objects inherit this class.
|
|
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].
|
|
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.
