Modifier and Type	Method and Description
protected boolean	accept(ScrollableHitSource.Hit doc) Used to accept or ignore a search hit.
protected AbstractAsyncBulkByScrollAction.RequestWrapper<DeleteRequest>	buildRequest(ScrollableHitSource.Hit doc) Build the AbstractAsyncBulkByScrollAction.RequestWrapper for a single search hit.
protected AbstractAsyncBulkByScrollAction.RequestWrapper<?>	copyMetadata(AbstractAsyncBulkByScrollAction.RequestWrapper<?> request, ScrollableHitSource.Hit doc) Overrides the parent's implementation is much more Update/Reindex oriented and so also copies things like timestamp/ttl which we don't care for a deletion.
protected boolean	needsSourceDocumentVersions() Does this operation need the versions of the source documents?

Method Detail

needsSourceDocumentVersions

protected boolean needsSourceDocumentVersions()

Description copied from class: AbstractAsyncBulkByScrollAction

Does this operation need the versions of the source documents?

Specified by:

needsSourceDocumentVersions in class AbstractAsyncBulkByScrollAction<DeleteByQueryRequest>

accept

protected boolean accept(ScrollableHitSource.Hit doc)

Description copied from class: AbstractAsyncBulkByScrollAction

Used to accept or ignore a search hit. Ignored search hits will be excluded from the bulk request. It is also where we fail on invalid search hits, like when the document has no source but it's required.

Overrides:

accept in class AbstractAsyncBulkByScrollAction<DeleteByQueryRequest>

buildRequest

protected AbstractAsyncBulkByScrollAction.RequestWrapper<DeleteRequest> buildRequest(ScrollableHitSource.Hit doc)

Description copied from class: AbstractAsyncBulkByScrollAction

Build the AbstractAsyncBulkByScrollAction.RequestWrapper for a single search hit. This shouldn't handle metadata or scripting. That will be handled by copyMetadata and apply functions that can be overridden.

Specified by:

buildRequest in class AbstractAsyncBulkByScrollAction<DeleteByQueryRequest>

copyMetadata

protected AbstractAsyncBulkByScrollAction.RequestWrapper<?> copyMetadata(AbstractAsyncBulkByScrollAction.RequestWrapper<?> request,
                                                                         ScrollableHitSource.Hit doc)

Overrides the parent's implementation is much more Update/Reindex oriented and so also copies things like timestamp/ttl which we don't care for a deletion.

Overrides:
