Class ReferenceCountUpdater<T extends ReferenceCounted>

java.lang.Object
io.netty.util.internal.ReferenceCountUpdater<T>
Direct Known Subclasses:
AtomicReferenceCountUpdater, UnsafeReferenceCountUpdater, VarHandleReferenceCountUpdater
@Deprecated public abstract class ReferenceCountUpdater<T extends ReferenceCounted> extends java.lang.Object
Deprecated.
Instead of extending this class, prefer instead to include a RefCnt field and delegate to that. This approach has better compatibility with Graal Native Image.
