Class CalculateInputFromDelegateOption<S extends FeatureInput, T extends FeatureInput, U>

Object

CalculationPart<Optional<S>, T>

CalculateInputFromDelegate<Optional<S>, T, U>

CalculateInputFromDelegateOption<S,T,U>

Type Parameters:

S - optional final-type of CalculationPart.

T - feature input-type as input to cached-calculations.

U - delegate-type of CalculationPart.

All Implemented Interfaces:

ResettableCalculation

public abstract class CalculateInputFromDelegateOption<S extends FeatureInput, T extends FeatureInput, U>
extends CalculateInputFromDelegate<Optional<S>, T, U>

Like CalculateInputFromDelegate except assumes optional return value and no parameters.

CalculateInputFromDelegateOption

protected CalculateInputFromDelegateOption(ResolvedPart<U,T> delegate)

Creates with a delegate.

Parameters:

delegate - the resolved-calculation for the delegate.

Method Details

calc

public static <S extends FeatureInput, T extends FeatureInput, U>
double calc(FeatureCalculationInput<T> input,
 CalculationPart<U,T> delegate,
 Function<ResolvedPart<U,T>, CalculateInputFromDelegateOption<S,T,U>> createFromDelegate,
 Feature<S> feature,
 ChildCacheName cacheName,
 double emptyValue)
     throws FeatureCalculationException

Calculates a feature using a cached-calculation as delegate.

Type Parameters:

S - optional final input-type for calculation

T - input-type for calculation

U - delegate-type of CachedCalculation

Parameters:

input - feature-input.

delegate - the Cached-Calculation delegate used.

createFromDelegate - creates a calculation from the delegates.

feature - feature to use to calculate the output result.

cacheName - a sub-cache of the main cache to use for calculating the output feature.

emptyValue - what to return if the parameters are empty.

Returns:

the result of the feature calculation.

Throws:

FeatureCalculationException - if the calculation does not succeed successfully.
