public interface SafelyCloseable extends Closeable
Classes implementing this interface must provide a safety-net finaliser—a finaliser that closes the resource and logs that resource should have been closed.
When the implementing class is abstract, concrete subclasses must
super.close() in their own
to let the abstract class track correctly the resource. Moreover,
they must run
their own finaliser (if any), as finalisation chaining is not automatic.
Note that if a concrete subclass implements
readResolve(), it must
super.close(), or actually return
this (i.e., the deserialised
instance); otherwise, a spurious log could be generated when the deserialised instance is collected.
