Method Details

resolveFeatureIdentifier

String resolveFeatureIdentifier(String identifier)

Resolves an identifier to a unique-string, suitable for calculateFeatureByIdentifier(String, FeatureCalculationInput).

Parameters:

identifier - the identifier to resolve.

Returns:

the resolved identifier.

calculateFeatureByIdentifier

double calculateFeatureByIdentifier(String resolvedIdentifier,
 FeatureCalculationInput<T> input)
                             throws FeatureCalculationException

Searches for a feature that matches a particular identifier.

Parameters:

resolvedIdentifier - the identifier.

input - the feature-input to be calculated.

Returns:

the result of the calculation.

Throws:

FeatureCalculationException - if the feature cannot be successfully calculated.
