Example 1 with OffsetBasedPagination

use of org.n52.web.common.OffsetBasedPagination in project series-rest-api by 52North.

the class StationsParameterController method getCollection.

@Override
@RequestMapping(method = RequestMethod.GET)
public ModelAndView getCollection(HttpServletResponse response, @RequestHeader(value = Parameters.HttpHeader.ACCEPT_LANGUAGE, required = false) String httpLocale, @RequestParam(required = false) MultiValueMap<String, String> query) {
    IoParameters map = createParameters(query, httpLocale, response).respectBackwardsCompatibility();
    OutputCollection<?> result;
    if (map.isExpanded()) {
        Stopwatch stopwatch = Stopwatch.startStopwatch();
        result = parameterService.getExpandedParameters(map);
        logRequestTime(stopwatch);
    } else {
        Stopwatch stopwatch = Stopwatch.startStopwatch();
        result = parameterService.getCondensedParameters(map);
        logRequestTime(stopwatch);
    }
    // XXX refactor (is redundant here)
    if (map.containsParameter("limit") || map.containsParameter("offset")) {
        Long elementcount = this.counter.getStationCount();
        if (elementcount != -1) {
            OffsetBasedPagination obp = new OffsetBasedPagination(map.getOffset(), map.getLimit());
            Paginated paginated = new Paginated(obp, elementcount);
            String collectionHref = createCollectionUrl(getCollectionName());
            PageLinkUtil.addPagingHeaders(collectionHref, response, paginated);
        }
    }
    return new ModelAndView().addObject(result.getItems());
}

Example 2 with OffsetBasedPagination

use of org.n52.web.common.OffsetBasedPagination in project series-rest-api by 52North.

the class ParameterController method preparePagingHeaders.

private void preparePagingHeaders(IoParameters parameters, HttpServletResponse response) {
    if (parameters.containsParameter(Parameters.LIMIT) || parameters.containsParameter(Parameters.OFFSET)) {
        Long elementcount = this.getElementCount(parameters.removeAllOf(Parameters.LIMIT).removeAllOf(Parameters.OFFSET));
        if (elementcount > 0) {
            int limit = parameters.getLimit();
            int offset = parameters.getOffset();
            OffsetBasedPagination obp = new OffsetBasedPagination(offset, limit);
            Paginated paginated = new Paginated(obp, elementcount);
            PageLinkUtil.addPagingHeaders(createCollectionUrl(getCollectionName()), response, paginated);
        }
    }
