Method Details

createActionContext

protected Void createActionContext(Task task,
 GetSampleAction.Request request)

Description copied from class: TransportNodesAction

Create an (optional) TransportNodesAction: called when starting to execute this action, and the result passed to TransportNodesAction.newResponseAsync(org.elasticsearch.tasks.Task, NodesRequest, ActionContext, java.util.List<NodeResponse>, java.util.List<org.elasticsearch.action.FailedNodeException>, org.elasticsearch.action.ActionListener<NodesResponse>) on completion. NB runs on the transport worker thread, must not do anything expensive without dispatching to a different executor.

Overrides:

createActionContext in class TransportNodesAction<GetSampleAction.Request,GetSampleAction.Response,GetSampleAction.NodeRequest,GetSampleAction.NodeResponse,Void>

newResponse

protected GetSampleAction.Response newResponse(GetSampleAction.Request request,
 List<GetSampleAction.NodeResponse> nodeResponses,
 List<FailedNodeException> failures)

Description copied from class: TransportNodesAction

Create a new TransportNodesAction. This method is executed on TransportNodesAction.finalExecutor.

Specified by:

newResponse in class TransportNodesAction<GetSampleAction.Request,GetSampleAction.Response,GetSampleAction.NodeRequest,GetSampleAction.NodeResponse,Void>

Parameters:

request - The request whose response we are constructing. TransportNodesAction may have already released all its references to this object before calling this method, so it's up to individual implementations to retain their own reference to the request if still needed here.

nodeResponses - All successful node-level responses.

failures - All node-level failures.

Returns:

Never null.

newNodeRequest

protected GetSampleAction.NodeRequest newNodeRequest(GetSampleAction.Request request)

Specified by:

newNodeRequest in class TransportNodesAction<GetSampleAction.Request,GetSampleAction.Response,GetSampleAction.NodeRequest,GetSampleAction.NodeResponse,Void>

newNodeResponse

protected GetSampleAction.NodeResponse newNodeResponse(StreamInput in,
 DiscoveryNode node)
                                                throws IOException

Specified by:

newNodeResponse in class TransportNodesAction<GetSampleAction.Request,GetSampleAction.Response,GetSampleAction.NodeRequest,GetSampleAction.NodeResponse,Void>

Throws:

IOException

nodeOperation

protected GetSampleAction.NodeResponse nodeOperation(GetSampleAction.NodeRequest request,
 Task task)

Description copied from class: TransportNodesAction

Implements the request recipient logic. If access to the request listener is needed, override TransportNodesAction.nodeOperationAsync(TransportRequest, Task, ActionListener).

Specified by:

nodeOperation in class TransportNodesAction<GetSampleAction.Request,GetSampleAction.Response,GetSampleAction.NodeRequest,GetSampleAction.NodeResponse,Void>
