Class LocalCacheStatsImpl

java.lang.Object

com.hazelcast.monitor.impl.LocalCacheStatsImpl

All Implemented Interfaces:

JsonSerializable, LocalCacheStats, LocalInstanceStats, DataSerializable

public class LocalCacheStatsImpl
extends Object
implements LocalCacheStats

Default implementation of LocalCacheStats This class just provides serialization/deserialization methods to be used in MemberState implementation while sending/receiving statistics to/from Management center. There are no calculations are done in this class, all statistics gathered from CacheStatistics No setter methods are provided, all class fields supposed to be populated either by a CacheStatistics or while deserialization process (fromJson(com.eclipsesource.json.JsonObject), or readData(com.hazelcast.nio.ObjectDataInput)).
