Class WideLatch

java.lang.Object
org.cojen.tupl.util.WideLatch
public class WideLatch extends Object
Non-reentrant latch implementation which supports highly concurrent shared requests, but exclusive requests are more expensive. The implementation distributes shared state over multiple cells, and so it can consume more memory than a regular latch.
