readShardResult

protected TransportBroadcastByNodeAction.EmptyResult readShardResult(StreamInput in)
                                                              throws java.io.IOException

Description copied from class: TransportBroadcastByNodeAction

Deserialize a shard-level result from an input stream

Specified by:

readShardResult in class TransportBroadcastByNodeAction<ForceMergeRequest,ForceMergeResponse,TransportBroadcastByNodeAction.EmptyResult>

Parameters:

in - input stream

Returns:

a deserialized shard-level result

Throws:

java.io.IOException

newResponse

protected ForceMergeResponse newResponse(ForceMergeRequest request,
int totalShards,
int successfulShards,
int failedShards,
java.util.List<TransportBroadcastByNodeAction.EmptyResult> responses,
java.util.List<DefaultShardOperationFailedException> shardFailures,
ClusterState clusterState)

Description copied from class: TransportBroadcastByNodeAction

Creates a new response to the underlying request.

Specified by:

newResponse in class TransportBroadcastByNodeAction<ForceMergeRequest,ForceMergeResponse,TransportBroadcastByNodeAction.EmptyResult>

Parameters:

request - the underlying request

totalShards - the total number of shards considered for execution of the operation

successfulShards - the total number of shards for which execution of the operation was successful

failedShards - the total number of shards for which execution of the operation failed

responses - the per-node aggregated shard-level results

shardFailures - the exceptions corresponding to shard operation failures

clusterState - the cluster state

Returns:

the response

readRequestFrom

protected ForceMergeRequest readRequestFrom(StreamInput in)
                                     throws java.io.IOException

Description copied from class: TransportBroadcastByNodeAction

Deserialize a request from an input stream

Specified by:

readRequestFrom in class TransportBroadcastByNodeAction<ForceMergeRequest,ForceMergeResponse,TransportBroadcastByNodeAction.EmptyResult>

Parameters:

in - input stream

Returns:

a de-serialized request

Throws:

java.io.IOException

shardOperation

protected TransportBroadcastByNodeAction.EmptyResult shardOperation(ForceMergeRequest request,
ShardRouting shardRouting,
Task task)
                                                             throws java.io.IOException

Description copied from class: TransportBroadcastByNodeAction

Executes the shard-level operation. This method is called once per shard serially on the receiving node.

Specified by:

Parameters:

request - the node-level request

shardRouting - the shard on which to execute the operation

task - the task for this node-level request

Returns:

the result of the shard-level operation for the shard

Throws:

java.io.IOException
