@Override
public void endRow() {
    long rowHeaderPos = recordStartAddr();
    // curOffset is equivalent to a byte length of this row.
    PlatformDependent.putInt(rowHeaderPos, curOffset);
    rowHeaderPos += SizeOf.SIZE_OF_INT;//from w w  w. jav a 2  s. com

    //set null flags
    byte[] flags = nullFlags.toArray();
    PlatformDependent.putShort(rowHeaderPos, (short) flags.length);
    rowHeaderPos += SizeOf.SIZE_OF_SHORT;
    PlatformDependent.copyMemory(flags, 0, rowHeaderPos, flags.length);

    rowBlock.setRows(rowBlock.rows() + 1);
