Method Details

initialize

public void initialize(Map<ActionType<? extends ActionResponse>,TransportAction<? extends ActionRequest,? extends ActionResponse>> actions,
 TaskManager taskManager,
 Supplier<String> localNodeId,
 Transport.Connection localConnection,
 RemoteClusterService remoteClusterService)

getActionNames

public List<String> getActionNames()

Return the names of all available actions registered with this client.

doExecute

public <Request extends ActionRequest,
Response extends ActionResponse>
void doExecute(ActionType<Response> action,
 Request request,
 ActionListener<Response> listener)

Specified by:

doExecute in class AbstractClient

executeLocally

public <Request extends ActionRequest,
Response extends ActionResponse>
Task executeLocally(ActionType<Response> action,
 Request request,
 ActionListener<Response> listener)

Execute an ActionType locally, returning that Task used to track it, and linking an ActionListener. Prefer this method if you don't need access to the task when listening for the response. This is the method used to implement the Client interface.

Throws:

TaskCancelledException - if the request's parent task has been cancelled already

getLocalNodeId

public String getLocalNodeId()

The id of the local DiscoveryNode. Useful for generating task ids from tasks returned by executeLocally(ActionType, ActionRequest, ActionListener).

getRemoteClusterClient

public RemoteClusterClient getRemoteClusterClient(String clusterAlias,
 Executor responseExecutor,
 RemoteClusterService.DisconnectedStrategy disconnectedStrategy)

Description copied from interface: Client

Returns a client to a remote cluster with the given cluster alias.
