A primary-key postings format that associates a version (long) with each term and can provide fail-fast lookups by ID and version.

Class Summary

Class	Description
IDVersionPostingsFormat	A PostingsFormat optimized for primary-key (ID) fields that also record a version (long) for each ID, delivered as a payload created by IDVersionPostingsFormat.longToBytes(long, org.apache.lucene.util.BytesRef) during indexing.
IDVersionSegmentTermsEnum	Iterates through terms in this field; this class is public so users can cast it to call IDVersionSegmentTermsEnum.seekExact(BytesRef, long) for optimistic-concurrency, and also IDVersionSegmentTermsEnum.getVersion() to get the version of the currently seek'd term.
VersionBlockTreeTermsReader	See VersionBlockTreeTermsWriter.
VersionBlockTreeTermsWriter	This is just like BlockTreeTermsWriter, except it also stores a version per term, and adds a method to its TermsEnum implementation to seekExact only if the version is >= the specified version.
