toXContentChunked
Description copied from interface:ChunkedToXContentCreate an iterator ofToXContentchunks for a REST response. Each chunk is serialized with the sameXContentBuilderandToXContent.Params, which is also the same as theToXContent.Paramspassed as theparamsargument. For best results, all chunks should beO(1)size. The last chunk in the iterator must always yield at least one byte of output. See alsoChunkedToXContentHelperfor some handy utilities.Note that chunked response bodies cannot send deprecation warning headers once transmission has started, so implementations must check for deprecated feature use before returning.
- Specified by:
toXContentChunkedin interfaceChunkedToXContent- Returns:
- iterator over chunks of
ToXContent
-
