Examples of org.geotools.parameter.DefaultParameterDescriptor

org.geotools.parameter.DefaultParameterDescriptor
The definition of a parameter used by an operation method. For {@linkplain org.opengis.referencing.crs.CoordinateReferenceSystem CoordinateReference Systems} most parameter values are numeric, but other typesof parameter values are possible.
For numeric values, the {@linkplain #getValueClass value class} is usually {@linkplain Double}.class, {@linkplain Integer}.class or some other Java wrapper class.
This class contains numerous convenience constructors. But all of them ultimately invoke {@linkplain #DefaultParameterDescriptor(Map,Class,Object[],Object,Comparable,Comparable,Unit,boolean) a single, full-featured constructor}. All other constructors are just shortcuts. @param < T> The type of elements to be returned by {@link ParameterValue#getValue}. @since 2.1 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD) @see Parameter @see DefaultParameterDescriptorGroup
