clone
public TermVectorsReader clone()
Description copied from class:TermVectorsReaderCreate a clone that one caller at a time may use to read term vectors.- Specified by:
clonein classTermVectorsReader

getMergeInstance
public TermVectorsReader getMergeInstance()
Description copied from class:TermVectorsReaderReturns an instance optimized for merging. This instance may only be consumed in the thread that calledTermVectorsReader.getMergeInstance().The default implementation returns
this- Overrides:

-
get
public Fields get(int doc) throws IOException
Description copied from class:TermVectorsReturns term vectors for this document, or null if term vectors were not indexed.The returned Fields instance acts like a single-document inverted index (the docID will be 0). If offsets are available they are in an
OffsetAttributeavailable from thePostingsEnum.- Specified by:
getin classTermVectors- Throws:
IOException
-
checkIntegrity
public void checkIntegrity() throws IOExceptionDescription copied from class:TermVectorsReaderChecks consistency of this reader.Note that this may be costly in terms of I/O, e.g. may involve computing a checksum value against large data files.
