Detailed Description

A table cell which contains a formula.

Implements the Cell class by storing a formula as a String and in a dynamic List

Member Function Documentation

getNumeralValue()

double CellFormula::getNumeralValue ( ) const

overridevirtual

Value is recalculated every time this function is called (in case a referenced cell is changed).

Returns

0

Implements Cell.

getValueForPrint()

String CellFormula::getValueForPrint ( ) const

overridevirtual

Value is recalculated every time this function is called (in case a referenced cell is changed).

Returns

"Error"

Implements Cell.

parseAndSetValue()

void CellFormula::parseAndSetValue ( const char *  str )

overridevirtual

Each math operation is represented with a Pair that holds indecies of cell reference and a character for the operation.

Negatve value for the operation character means it's with priority and the result get's calculated immediately (rather than recursively, taking into account other values).

Exceptions

std::logic_error("Error

Invalid column character!") Thrown when there is something between Rx and C in cell references \exception std::logic_error("Error: Invalid value!") Thrown when met value isn't a cell reference or number \exception throw std::logic_error("Error: Could not find operand!") Thrown when there isn't an operator character between two values

Implements Cell.

writeToFile()

void CellFormula::writeToFile ( std::ofstream &  file )

overridevirtual

Writes value to a text file.

Implements Cell.
