getColumnSort

method

in

org.apache.tapestry5.grid.SortConstraint

protected SortConstraint getSortConstraint(
    List<SortConstraint> sortConstraints) {
  for (SortConstraint constraint : sortConstraints) {
    final ColumnSort sort = constraint.getColumnSort();
    if (sort != ColumnSort.UNSORTED) {
      return constraint;
    }
  }
  return null;
}

protected String resolveOrderBy(SortConstraint orderBy) {
  String filterOrder = null;
  if (orderBy != null) {
    PropertyModel property = orderBy.getPropertyModel();
    filterOrder = property.getPropertyName();
    ColumnSort sort = orderBy.getColumnSort();
    if (sort.equals(ColumnSort.DESCENDING)) {
      filterOrder += " desc";
    }
    if (log.isDebugEnabled()) {
      log.debug("Order : " + filterOrder);
    }
  }
  return filterOrder;
}

final ColumnSort sort = constraint.getColumnSort();

switch (constraint.getColumnSort())

switch (constraint.getColumnSort())

final ColumnSort sort = constraint.getColumnSort();

switch (constraint.getColumnSort())

switch (constraint.getColumnSort())

switch (constraint.getColumnSort()) {
case ASCENDING:
  beanQuery.orderBy(propertyPath.asc());
