public double calculate(FeatureCalculationInput<T> input)
                 throws FeatureCalculationException

Description copied from class: Feature

Calculates a value for some input.

Specified by:

calculate in class Feature<T extends FeatureInput>

Parameters:

input - the input to the calculation.

Returns:

the result of the calculation.

Throws:

FeatureCalculationException - if the calculation cannot successfully complete.

descriptionLong

public String descriptionLong()

Description copied from class: Feature

A long human-readable description of the feature and some or all of its parameterization.

This can be overwritten to create an alternative description for features. By default string returned by Feature.describeBean() is used.

Overrides:

descriptionLong in class Feature<T extends FeatureInput>

Returns:

the description.
