Method Details

of

public static Ellipsoid of(FeatureCalculationInput<FeatureInputSingleObject> input,
 boolean suppressZCovariance)
                    throws FeatureCalculationException

Calculates an Ellipsoid for the given input.

Parameters:

input - the feature calculation input

suppressZCovariance - whether to suppress covariance in the Z direction

Returns:

the calculated Ellipsoid

Throws:

FeatureCalculationException - if the calculation fails

execute

protected Ellipsoid execute(FeatureInputSingleObject input)
                     throws FeatureCalculationException

Description copied from class: CalculationPart

This performs the actual calculation when needed. It should only be called once, until CalculationPart.invalidate() is called.

Specified by:

execute in class CalculationPart<Ellipsoid,FeatureInputSingleObject>

Parameters:

input - the input to the calculation.

Returns:

the result of the calculation.

Throws:

FeatureCalculationException - if the calculation cannot be successfully completed.
