T - The type of elements to be returned by ParameterValue.getValue().public class DefaultParameterDescriptor<T> extends AbstractParameterDescriptor implements ParameterDescriptor<T>
For numeric values, the value class is usually
Double.class, Integer.class or
some other Java wrapper class.
This class contains numerous convenience constructors. But all of them ultimately invoke a single, full-featured constructor. All other constructors are just shortcuts.
