Class NotImplementedFunction

java.lang.Object
org.apache.poi.ss.formula.functions.NotImplementedFunction
All Implemented Interfaces:
Function

public final class NotImplementedFunction extends Object implements Function
This is the default implementation of a Function class. The default behaviour is to raise a POI internal error (NotImplementedFunctionException). This error should alert the user that the formula contained a function that is not yet implemented.

    • evaluate

      public ValueEval evaluate(ValueEval[] operands, int srcRow, int srcCol)
      Specified by:
      evaluate in interface Function
      Parameters:
      operands - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
      srcRow - row index of the cell containing the formula under evaluation
      srcCol - column index of the cell containing the formula under evaluation
      Returns:
      The evaluated result, possibly an ErrorEval, never null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to Double.NaN be sure to translate the result to ErrorEval.NUM_ERROR.
