use of org.knime.core.data.vector.bitvector.DenseBitVectorCell in project knime-core by knime.

the class BitVectorPerformanceComparisonBug1532 method createNewDenseBitVectorCells.

    Random r = new Random(seed);
    DenseBitVectorCell[] result = new DenseBitVectorCell[count];

    StringBuilder b = new StringBuilder(hexLength);
    for (int i = 0; i < count; i++) {
        b.setLength(0);
