CacheEntryVersion (Ignite 2.17.0)

All Superinterfaces:

Comparable<CacheEntryVersion>, Serializable

All Known Implementing Classes:

GridCacheVersion, GridCacheVersionEx
```
public interface CacheEntryVersion
extends Comparable<CacheEntryVersion>, Serializable
```
Entry event order. Two concurrent updates of the same entry can be ordered based on CacheEntryVersion comparsion. Greater value means that event occurs later.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`byte`	`clusterId()`	Cluster id is a value to distinguish updates in case user wants to aggregate and sort updates from several Ignite clusters.
`int`	`nodeOrder()`
`long`	`order()`	Order of the update.
`CacheEntryVersion`	`otherClusterVersion()`	If source of the update is "local" cluster then `null` will be returned.

- Method Detail
  - order
```
long order()
```
    Order of the update. Value is an incremental counter value. Scope of counter is node.
    
    Returns:
    
    Version order.
  - nodeOrder
```
int nodeOrder()
```
    Returns:
    
    Node order on which this version was assigned.
  - clusterId
```
byte clusterId()
```
    Cluster id is a value to distinguish updates in case user wants to aggregate and sort updates from several Ignite clusters. clusterId id can be set for the node using GridCacheVersionManager.dataCenterId(byte).
    
    Returns:
    
    Cluster id.
  - topologyVersion
```
int topologyVersion()
```
    Returns:
    
    Topology version plus number of seconds from the start time of the first grid node.
  - otherClusterVersion
```
CacheEntryVersion otherClusterVersion()
```
    If source of the update is "local" cluster then null will be returned. If updated comes from the other cluster using IgniteInternalCache.putAllConflict(Map) then entry version for other cluster.
    
    Returns:
    
    Replication version.
