Detailed Description
Extends TermFreqVector to provide additional information about positions in which each of the terms is found.
A TermPositionVector not necessarily contains both positions and offsets, but at least one of these arrays exists.

Member Function Documentation
| virtual Array<TermVectorOffsetInfo>* lucene::index::TermPositionVector::getOffsets | ( | int32_t | index | ) | [pure virtual] |
Returns an array of TermVectorOffsetInfo in which the term is found.
May return null if offsets have not been stored.

- Parameters:
-
index The position in the array to get the offsets from
- Returns:
- An array of TermVectorOffsetInfo objects or the empty list
Implemented in lucene::index::SegmentTermPositionVector.
| virtual Array<int32_t>* lucene::index::TermPositionVector::getTermPositions | ( | int32_t | index | ) | [pure virtual] |
Returns an array of positions in which the term is found.
Terms are identified by the index at which its number appears in the term String array obtained from the indexOf method. May return null if positions have not been stored.
Implemented in lucene::index::SegmentTermPositionVector.
