Examples with NumberRange org.apache.sis.measure.NumberRange used on opensource projects

Example 1 with NumberRange

use of org.apache.sis.measure.NumberRange in project sis by apache.

the class Parameters method getValueDomain.

/**
 * Returns the domain of valid values defined by the given descriptor, or {@code null} if none.
 * This method performs the following operations:
 *
 * <ul>
 *   <li>If the given parameter is an instance of {@code DefaultParameterDescriptor},
 *       delegate to {@link DefaultParameterDescriptor#getValueDomain()}.</li>
 *   <li>Otherwise builds the range from the {@linkplain DefaultParameterDescriptor#getMinimumValue() minimum value},
 *       {@linkplain DefaultParameterDescriptor#getMaximumValue() maximum value} and, if the values are numeric, from
 *       the {@linkplain DefaultParameterDescriptor#getUnit() unit}.</li>
 * </ul>
 *
 * @param  descriptor  the parameter descriptor, or {@code null}.
 * @return the domain of valid values, or {@code null} if none.
 *
 * @see DefaultParameterDescriptor#getValueDomain()
