Class NullParameter

java.lang.Object
  info.javelot.functionalj.reflect.Parameter
      info.javelot.functionalj.reflect.NullParameter

All Implemented Interfaces:

Serializable

public class NullParameter
extends Parameter

Used to indicate that a null value should be used for a parameter of a specific class, in order to remove the ambiguity caused by using simple null values when a method is overloaded with different parameter classes.

For example, if a method is overloaded, one which accepts a parameter of type String, the other of type Integer, and a null value is to be used as a parameter to the method which accepts a parameter of type Integer, the following code should be used:

function.addParameter(new NullParameter(Integer.class));
