org.geotools.processing.jai.nodata.Range

Abstract class used for checking if a selected value is inside the selected Range. All the methods throw an {@link UnsupportedOperationException}but for every subclass one of these methods is overridden with the correct functionality. These 6 methods are different only for the data type used. In this way it is possible to reach a better performance by using primitive variables than generic. All the subclasses can contain a Range composed by a minimum and a maximum or a single-point Range. For Double and Float data type the NaN data can be used only with a single-point Range. @author Nicola Lagomarsini, GeoSolutions S.A.S.
