Class ChronicleStampedLock

java.lang.Object

java.util.concurrent.locks.StampedLock

net.openhft.chronicle.map.locks.ChronicleStampedLock

All Implemented Interfaces:

Serializable

public class ChronicleStampedLock
extends StampedLock

[email protected]

A totally hacked impl, awaiting OpenHFT's official ChronicleStampedLock API

A usable 'reference' impl will more properly belong in the Chronicle-Algorithms/ repo

NOTE: This impl only provides off-Heap capability for the tryXXXXX() family of j.u.c.l.StampedLock methosds.
