Methods Summary
public org.apache.lucene.index.TermVectorOffsetInfo[]getOffsets(int index)
Returns an array of TermVectorOffsetInfo in which the term is found.

param
index The position in the array to get the offsets from
return
An array of TermVectorOffsetInfo objects or the empty list

    TermVectorOffsetInfo[] result = TermVectorOffsetInfo.EMPTY_OFFSET_INFO;
    if(offsets == null)
      return null;
    if (index >=0 && index < offsets.length)
    {
      result = offsets[index];
    }
    return result;
  
public int[]getTermPositions(int index)
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.

    int[] result = EMPTY_TERM_POS;
    if(positions == null)
      return null;
    if (index >=0 && index < positions.length)
    {
      result = positions[index];
    }
    
    return result;
