Hardcoded checksum mechanism in BlockTreeTermsReader

[Duke DAI]

Hi all,

I'm customizing Lucene Directory, which extends o.a.l.store.Directory based
on database files. I do not need checksum again on IndexIndex and
IndexOutput.

But in BlockTreeTermsReader constructor, following code open a
hard-coded BufferedChecksumIndexInput to checksum on raw IndexInput. I have
to use CRC32 on IndexOutput to make through it. Is there any more graceful
way to do checksum, such as let Directory construct a checksum instance
instead of API Directory.openChecksumInput ?


      String indexName = IndexFileNames.segmentFileName(segment,
state.segmentSuffix, TERMS_INDEX_EXTENSION);
      indexIn = state.directory.openInput(indexName, state.context);
      CodecUtil.checkIndexHeader(indexIn, TERMS_INDEX_CODEC_NAME, version,
version, state.segmentInfo.getId(), state.segmentSuffix);
      CodecUtil.checksumEntireFile(indexIn);




Best regards,
Duke
