public final class Null

extends java.lang.Object

NULL values for built-in Inline Service data types. RTD generated ILS code follows a convention of using distinguished values to represent nulls for primitives. This utility class may be used to test for null. For example:

int id = request.getCustomerId(); if (!Null.isNull(id)) { ... }
