public class ERXValueUtilities extends Object
boolean,
int and floatvalues.
Unless otherwise stated, when an empty string
(or one containing only whitespace) is given, then
the string is assumed to be null. This is because
D2W is not able to give back null values anymore.| Constructor and Description |
