Modifier and Type	Method	Description
`void`	`initializedReplicaReinitialized(ShardRouting oldReplica, ShardRouting reinitializedReplica)`	Called when an initializing replica is reinitialized.
`void`	`relocationCompleted(ShardRouting removedRelocationSource)`	Called on relocation source when relocation completes after relocation target is started.
`void`	`relocationSourceRemoved(ShardRouting removedReplicaRelocationSource)`	Called on replica relocation target when replica relocation source fails.
`void`	`relocationStarted(ShardRouting startedShard, ShardRouting targetRelocatingShard)`	Called when relocation of a started shard is initiated.
`void`	`replicaPromoted(ShardRouting replicaShard)`	Called when started replica is promoted to primary.
`void`	`shardFailed(ShardRouting failedShard, UnassignedInfo unassignedInfo)`	Called when a shard is failed or cancelled.
`void`	`shardInitialized(ShardRouting unassignedShard, ShardRouting initializedShard)`	Called when unassigned shard is initialized.
`void`	`shardStarted(ShardRouting initializingShard, ShardRouting startedShard)`	Called when an initializing shard is started.
`void`	`startedPrimaryReinitialized(ShardRouting startedPrimaryShard, ShardRouting initializedShard)`	Called on started primary shard after it has been promoted from replica to primary and is reinitialized due to shadow replicas.
`void`	`unassignedInfoUpdated(ShardRouting unassignedShard, UnassignedInfo newUnassignedInfo)`	Called when an unassigned shard's unassigned information was updated

void shardInitialized(ShardRouting unassignedShard,
                      ShardRouting initializedShard)

Called when unassigned shard is initialized. Does not include initializing relocation target shards.

void shardStarted(ShardRouting initializingShard,
                  ShardRouting startedShard)

Called when an initializing shard is started.

void relocationStarted(ShardRouting startedShard,
                       ShardRouting targetRelocatingShard)

Called when relocation of a started shard is initiated.

void unassignedInfoUpdated(ShardRouting unassignedShard,
                           UnassignedInfo newUnassignedInfo)

Called when an unassigned shard's unassigned information was updated

void shardFailed(ShardRouting failedShard,
                 UnassignedInfo unassignedInfo)

Called when a shard is failed or cancelled.

relocationCompleted
```
void relocationCompleted(ShardRouting removedRelocationSource)
```
Called on relocation source when relocation completes after relocation target is started.

relocationSourceRemoved
```
void relocationSourceRemoved(ShardRouting removedReplicaRelocationSource)
```
Called on replica relocation target when replica relocation source fails. Promotes the replica relocation target to ordinary initializing shard.

void startedPrimaryReinitialized(ShardRouting startedPrimaryShard,
                                 ShardRouting initializedShard)

Called on started primary shard after it has been promoted from replica to primary and is reinitialized due to shadow replicas.

replicaPromoted
```
void replicaPromoted(ShardRouting replicaShard)
```
Called when started replica is promoted to primary.
