Example 6 with ParameterBuilder

use of org.apache.sis.parameter.ParameterBuilder in project sis by apache.

the class NormalizedProjection method getParameterDescriptors.

/**
 * Returns a description of the non-linear internal parameters of this {@code NormalizedProjection}.
 * The returned group contains at least a descriptor for the {@link #eccentricity} parameter.
 * Subclasses may add more parameters.
 *
 * <p>This method is for inspecting the parameter values of this non-linear kernel only,
 * not for inspecting the {@linkplain #getContextualParameters() contextual parameters}.
 * Inspecting the kernel parameter values is usually for debugging purpose only.</p>
 *
 * @return a description of the internal parameters.
