All Implemented Interfaces:
JCacheStatistics, ExternalizableLite, PortableObject, Serializable, javax.cache.management.CacheStatisticsMXBean
public class ContextJCacheStatistics extends AbstractJCacheStatistics implements JCacheStatistics, ExternalizableLite, PortableObject
JCache Statistics implementation. JCache cache statistics differed enough from current Coherence cache statistics that just ended up maintaining statistics separately. Examples of differences include put of same value is optimized in Coherence implementation but JCache considers them 2 distinct puts. (could not pass jsr 107 tck with that behavior) Additionally, coherence does not count removals at the time this was written.
Since:
Coherence 12.1.3
