LocalMapStats (Hazelcast Root 4.2 API)

All Superinterfaces:

com.hazelcast.instance.LocalInstanceStats

All Known Subinterfaces:

LocalMultiMapStats, LocalReplicatedMapStats
```
public interface LocalMapStats
extends com.hazelcast.instance.LocalInstanceStats
```
Local map statistics to be used by MemberState implementations.
As IMap is a partitioned data structure in Hazelcast, each member owns a fraction of the total number of entries of a distributed map.
Depending on the IMap's configuration, each member may also hold backup entries of other members. LocalMapStats provides the count of owned and backup entries besides their size in memory.
