code: protected void addIdInArrayCondition(final Expression<?> property, final String[] values) throws NumberFormatException {
          final Set<Integer> idValues = new HashSet<Integer>();
          for (final String value : values) {
              idValues.add(Integer.parseInt(value.trim()));
          }
          addIdInCollectionCondition(property, idValues);
      }
docs: Add a Field Search Condition that will check if the id field exists in an array of id values that are represented as a
  String. eg. {@code field IN (values)}
  
  @param property The field id as defined in the Entity mapping class.
  @param values   The array of Ids to be compared to.
  @throws NumberFormatException Thrown if one of the Strings cannot be converted to an Integer.
