public abstract class AbstractCalculationEngine 
extends java.lang.Object

public boolean isParamLiteralRequired()

Indicates whether this engine needs the literal text of parameter while doing calculation. Default value is false.

If this custom calculation engine requires the parameter's literal text, more stacks will be required to cache the literal text for parameters and Calculate() method may be called recursively to calcualte the parameter's value. Commonly the literal text is not needed for calculating formulas and this method should return false for most implementations to get better performance.

public abstract void calculate(CalculationData data)

Calculates one function with given data.

User should set the calculated value for given data for all functions(including excel native functions) that he wants to calculate by himself in this implementation.

Parameters:

data - the required data to calculate function such as function name, parameters, ...etc.
