Algorithms often depend on other algorithms during the computation. Sometimes it is desirable to interchange dependent algorithms. Strategy objects facilitate this. A Strategy is a mechanism for interchanging the algorithms which are used to compute a quantity. A Strategy is a one-to-one mapping between algorithm type (such as BackscatterFactor.class or MassAbsorptionCoefficient.class) and the algorithm implementing this algorithm-type (such as BackscatterFactor.Pouchou1991 or MassAbsorptionCoefficient.Chantler2005). Each instance of the AlgorithmClass understands what other types of AlgorithmClass it requires to perform its operations and can provide a list of the default algorithms as its default Strategy. The defaults algorithms can be overridden using the AlgorithmClass.apply(Strategy ) method. Strategy objects enforce consistency across a calculation.
