clone
public TermVectorsReader clone()
Description copied from class:TermVectorsReader
Create a clone that one caller at a time may use to read term vectors.- Specified by:
clone
in classTermVectorsReader
-
get
public Fields get(int doc) throws IOException
Description copied from class:TermVectorsReader
Returns term vectors for this document, or null if term vectors were not indexed. If offsets are available they are in anOffsetAttribute
available from thePostingsEnum
.- Specified by:
