- All Implemented Interfaces:
- SimpleMap
- public final class ScalableIdentityMap
- extends AbstractScalableMap
Reduce locking overhead for a map with few writers and many
readers. Writes are five times more expensive than a SimpleMap,
reads cost only slightly more. However, five readers can access
the same value simultaneously, without blocking.
This class uses SimpleIdentityMap as its implementation. See
description of SimpleIdentity for behaviour of this map.
