PowerOfOperation

public PowerOfOperation(FormulaValue value1,
 FormulaValue value2)

Parameters:

value1 - first FormulaValue of the power operation

value2 - second FormulaValue of the power operation

Method Details

getValue

public double getValue(Feature feature)

Description copied from class: FormulaValue

Returns the value (as a double) of this part of the formula. It may be the result of a sub-formula, a feature-specific attribute value or just a constant value... Since the value may depend on a feature, we give the feature to the method to get a unified interface...

Specified by:

getValue in class FormulaValue

Parameters:

feature - feature to process

Returns:

Math.pow(value1, value2)

toString

public String toString()

Overrides:
