  • Method Details

    • numLeaves

      int numLeaves()
      number of leaf nodes

    • getLeafLP

      long getLeafLP(int index)
      pointer to the leaf node previously written. Leaves are order from left to right, so leaf at index 0 is the leftmost leaf and the the leaf at numleaves() -1 is the rightmost leaf

    • getSplitValue

      BytesRef getSplitValue(int index)
      split value between two leaves. The split value at position n corresponds to the leaves at (n -1) and n.

    • getSplitDimension

      int getSplitDimension(int index)
      split dimension between two leaves. The split dimension at position n corresponds to the leaves at (n -1) and n.
