Method Detail

getLongValue

protected static long getLongValue(Ptg[] operands)

getLongValue is for single-operand functions. It returns NaN for calculations that have too many operands.

Parameters:

operands -

Returns:

getLongValue

protected static long getLongValue(Ptg operand)

getLongValueArray

protected static long[] getLongValueArray(Ptg[] operands)

getDoubleValueArray

protected static double[] getDoubleValueArray(Ptg[] operands)
                                       throws CalculationException

getDoubleValue is for multi-operand functions. It returns NaN for calculations that have to many operands.

Parameters:

operands -

Returns:

Throws:

CircularReferenceException - TODO

CalculationException

getDoubleValueArray

protected static double[] getDoubleValueArray(Ptg operands)
                                       throws CalculationException

Throws:

CalculationException

getArray

protected static double[][] getArray(Ptg operand)
                              throws Exception

return a 2-dimenional array of double values i.e. keep array structure of reference and array type parameters
ASSUMPTIONS:
1- accepts only 2-d references i.e. ranges are on 1 sheet
2- assumes that range reference are in proper notation i.e A1:B6, NOT B6:A1

Parameters:

operand - Ptg

Returns:

double[][]

Throws:

Exception

getError

protected static Ptg getError()

getValueError

protected static Ptg getValueError()

returns an #VALUE! error ptg

Returns:

getNAError

protected static Ptg getNAError()

returns an #NA! error ptg

Returns:

getAllComponents

protected static Ptg[] getAllComponents(Ptg[] operands)

getAllComponents

protected static Ptg[] getAllComponents(Ptg operand)

getBooleanValue

protected static boolean getBooleanValue(Ptg operand)
