Interface TermPositionVector

  • All Superinterfaces:
    TermFreqVector
    All Known Implementing Classes:
    InstantiatedTermPositionVector

    public interface TermPositionVector
    extends TermFreqVector
    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.
    • Method Detail

      • getTermPositions

        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. May return null if positions have not been stored.
      • getOffsets

        TermVectorOffsetInfo[] getOffsets​(int index)
        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
