Example 1 with IncrementalListResponse

use of org.apache.cayenne.util.IncrementalListResponse in project cayenne by apache.

the class ClientServerChannelQueryAction method interceptIncrementalListConversion.

private boolean interceptIncrementalListConversion() {
    int pageSize = serverMetadata.getPageSize();
    if (pageSize > 0 && serverMetadata.getCacheKey() != null) {
        List list = response.firstList();

            // cache
            channel.getQueryCache().put(serverMetadata, list);
            // extract and convert first page
            // TODO: andrus, 2008/03/05 - we no longer resolve the first page
            // automatically on the server... probably should not do it for the client
            // either... One rare case when this is completely undesirable is
            // subaction execution from 'interceptSinglePageQuery', as it doesn't even
            // care about the first page...
            List sublist = list.subList(0, pageSize);
            List firstPage = (serverMetadata.isFetchingDataRows()) ? new ArrayList(sublist) : toClientObjects(sublist);
