NumberValidator

java.lang.Object
- net.dpml.cli.validation.NumberValidator

All Implemented Interfaces:

Validator
```
public class NumberValidator
extends java.lang.Object
implements Validator
```
The NumberValidator validates the string argument values are numbers. If the value is a number, the string value in the List of values is replaced with the Number instance. A maximum and minimum value can also be specified using the setMaximum, and the setMinimum methods. The following example shows how to limit the valid values for the age attribute to integers less than 100.
```
 ...
 ArgumentBuilder builder = new ArgumentBuilder();
 NumberValidator validator = NumberValidator.getIntegerInstance();
 validator.setMaximum(new Integer(100));

 Argument age =
     builder.withName("age");
            .withValidator(validator);
 
```
