## Class MissingArgEval

- java.lang.Object
- - org.apache.poi.ss.formula.eval.MissingArgEval

- All Implemented Interfaces:
    ValueEval

      public final class MissingArgEval
      extends java.lang.Object
      implements ValueEval

  Represents the (intermediate) evaluated result of a missing function argument. In most cases this can be translated into `BlankEval` but there are some notable exceptions. Functions COUNT and COUNTA do count their missing args. Note - the differences between `MissingArgEval` and `BlankEval` have not been investigated fully, so the POI evaluator may need to be updated to account for these as they are found.
