Examples of org.geotools.util.Range

org.geotools.util.Range
A range between a minimum and maximum comparable. The minimum/maximum may be included, excluded or unbounded. The later case is indicated by {@code null} values on one or both ends.
This class is a method compatible replacement for the {@link javax.media.jai.util.Range} classwith the following differences:
- Unbounded ranges (i.e. {@code null} minimal or maximal values) are consideredexclusive rather than inclusive, since an iteration over the values will never reach the infinite bound. This interpretation brings some simplification in implementation and usage (e.g. a loop over the values should not attempt to process the {@code null} value).
- {@link #subtract} returns an empty array if the whole range is subtracted.
The exact {@linkplain #getElementClass element class} doesn't need to be known at compile time.Widening conversions are allowed as needed (subclasses like {@link NumberRange} do that). Thisclass is weakly parameterized in order to allow this flexibility. If any constructor or method is invoked with an argument value of illegal class, then an {@link IllegalArgumentException} isthrown. The {@link ClassCastException} is thrown only in case of bug in the {@code Range} classor subclasses implementation. @param < T> The type of range elements, typically {@link java.util.Date} or some subclassof {@link Number}. @since 2.5 @source $URL$ @version $Id$ @author Jody Garnett @author Martin Desruisseaux @see javax.media.jai.util.Range
