Prime input validation

Line: 63 to 60
 You can write a ParameterValidator to do just that:
    prime=new TaskParameter("spectrum",SpecificProduct.class)

<
<
validator=new ParameterValidator() { public boolean isValid(Object value) { SpecificProduct s=(SpecificProduct)value; ...logic that would validate the contents of the value... }
>
>
prime.setValidator(new ParameterValidatorAdapter() {
  public void validate(Object value) throws ParameterValidationException {
Changed:
<
<
if (isValid(value)) throw new ParameterValidationException(reason);
>
>
SpecificProduct s=(SpecificProduct)value; if (! (logic that would validate the contents of the value...)) { throw new ParameterValidationException(reason);
  } }
