Examples of org.opengis.filter.FilterFactory.sort()

org.opengis.filter.FilterFactory.sort()
Indicates an property by which contents should be sorted, along with intended order.

        FilterFactory ff = dataStore.getFilterFactory();
        QueryCapabilities caps = featureSource.getQueryCapabilities();
        
        // check we advertise support for sorting on basic attributes 
        assertTrue(caps.supportsSorting(new SortBy[] {ff.sort(aname("intProperty"), SortOrder.ASCENDING)}));
        assertTrue(caps.supportsSorting(new SortBy[] {ff.sort(aname("stringProperty"), SortOrder.DESCENDING)}));
        assertTrue(caps.supportsSorting(new SortBy[] {ff.sort(aname("doubleProperty"), SortOrder.ASCENDING)}));


        // but we cannot sort geometries
        assertFalse(caps.supportsSorting(new SortBy[] {ff.sort(aname("geometry"), SortOrder.ASCENDING)}));
