public interface LocalMapStats
extends LocalInstanceStats
```
Local map statistics. 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.

  - getCreationTime
```
long getCreationTime()
```
    Returns the creation time of this map on this member.
    
    Specified by:
    
    getCreationTime in interface LocalInstanceStats
    
    Returns:
    
    creation time of this map on this member.
  - getLastAccessTime
```
long getLastAccessTime()
```
    Returns the last access (read) time of the locally owned entries.
    
    Returns:
