All Implemented Interfaces:
Function

public final class Count extends Object implements Function
Counts the number of cells that contain numeric data within the list of arguments. Excel Syntax COUNT(value1,value2,...) Value1, value2, ... are 1 to 30 arguments representing the values or ranges to be counted. TODO: Check this properly matches excel on edge cases like formula cells, error cells etc

    • evaluate

      public ValueEval evaluate(ValueEval[] args, int srcCellRow, int srcCellCol)
      Specified by:
      evaluate in interface Function
      Parameters:
      args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
      srcCellRow - row index of the cell containing the formula under evaluation
      srcCellCol - 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.
    • subtotalInstance

      public static Count subtotalInstance()
      Create an instance of Count to use in Subtotal

      If there are other subtotals within argument refs (or nested subtotals), these nested subtotals are ignored to avoid double counting.
