public class ReindexRequest
extends AbstractBulkIndexByScrollRequest<ReindexRequest>
implements CompositeIndicesRequest

Request to reindex some documents from one index to another. This implements CompositeIndicesRequest but in a misleading way. Rather than returning all the subrequests that it will make it tries to return a representative set of subrequests. This is best-effort for a bunch of reasons, not least of which that scripts are allowed to change the destination request in drastic ways, including changing the index to which documents are written.

Method Detail

self

protected ReindexRequest self()

Description copied from class: AbstractBulkByScrollRequest

`this` cast to Self. Used for building fluent methods without cast warnings.

Specified by:

self in class AbstractBulkByScrollRequest<ReindexRequest>

validate

public ActionRequestValidationException validate()

Overrides:

validate in class AbstractBulkByScrollRequest<ReindexRequest>

getDestination

public IndexRequest getDestination()

readFrom

public void readFrom(StreamInput in)
              throws IOException

Specified by:

readFrom in interface Streamable

Overrides:

readFrom in class AbstractBulkIndexByScrollRequest<ReindexRequest>

Throws:

IOException

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Specified by:

writeTo in interface Streamable

Overrides:

writeTo in class AbstractBulkIndexByScrollRequest<ReindexRequest>

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object

subRequests

public List<? extends IndicesRequest> subRequests()

Accessor to get the underlying IndicesRequests that this request wraps. Note that this method is not accurate since it returns a prototype IndexRequest and not the actual requests that will be issued as part of the execution of this request. Additionally, scripts can modify the underlying IndexRequest and change values such as the index, type, IndicesOptions. In short - only use this for very course reasoning about the request.

Specified by:

subRequests in interface CompositeIndicesRequest

Returns:

a list comprising of the SearchRequest and the prototype IndexRequest
