    • null-ridding: nullFree, nullFreeIterable
    • mask conversion: eq, neq, isIn, isNotIn, maskFrom, gt, lt, geq, leq
  • Enable conditional rows selection based on columns, e.g.
    final filteredDf = df.masked(df('a').lt(7) & (df('b').eq(null) | df('c').isIn({'super', 'sick', ',', 'brother'})));
