Using Java to manage LIST constraints...

How do i retrieve the values of the LIST in Java… I have the following:<constraints> <constraint name="dwr:sectorList" type="LIST"> <parameter name="allowedValues"> <list> <value>Consumer Discretionary</value>

Figured it out…

For those who struggle.. this is how I did it…



// idQName is the aspect you are looking up
AspectDefinition aspectDef = this.dictionaryService.getAspect(idQName);
Iterator<PropertyDefinition> iterPropDefCol = aspectDef.getProperties().values().iterator();

while (iterPropDefCol.hasNext()) {
   PropertyDefinition propDef = iterPropDefCol.next();
   if (propDef.getName().getLocalName().equals(property)) {

      // Go through the constaints and see if it has the list of values constraint.
      ListIterator<ConstraintDefinition> constraintsIter = propDef.getConstraints().listIterator();
      
      while (constraintsIter.hasNext()) {
         Constraint constraint = ((ConstraintDefinition) constraintsIter.next()).getConstraint();

         if (constraint instanceof ListOfValuesConstraint) {
            ListIterator<String> valuesIter = ((ListOfValuesConstraint) constraint).getAllowedValues().listIterator();
            while (valuesIter.hasNext()) {
               constraintsList.add(new SelectItem(valuesIter.next()));
            }

            return constraintsList;
         }
      }
   }
}
