Method Details

doExecute

protected void doExecute(Task task,
 Request request,
 ActionListener<Response> listener)

Specified by:

doExecute in class TransportAction<Request extends BroadcastRequest<Request>,Response extends BroadcastResponse>

newResponse

protected abstract Response newResponse(Request request,
 AtomicReferenceArray<?> shardsResponses,
 ClusterState clusterState)

newShardRequest

protected abstract ShardRequest newShardRequest(int numShards,
 ShardRouting shard,
 Request request)

readShardResponse

protected abstract ShardResponse readShardResponse(StreamInput in)
                                            throws IOException

Throws:

IOException

shardOperation

protected abstract ShardResponse shardOperation(ShardRequest request,
 Task task)
                                         throws IOException

Throws:

IOException

shards

protected abstract GroupShardsIterator<ShardIterator> shards(ClusterState clusterState,
 Request request,
 String[] concreteIndices)

Determines the shards this operation will be executed on. The operation is executed once per shard iterator, typically on the first shard in it. If the operation fails, it will be retried on the next shard in the iterator.

checkGlobalBlock

protected abstract ClusterBlockException checkGlobalBlock(ClusterState state,
 Request request)

checkRequestBlock

protected abstract ClusterBlockException checkRequestBlock(ClusterState state,
 Request request,
 String[] concreteIndices)
