DefaultValueListHandlerImpl 的分页

DefaultValueListHandlerImpl 的分页

暂时没有太多时间求证,暂时记录在这里,根据这几句话好像是说valueList的分页也是假分页,仅仅是取ValueList的subList?

DefaultValueListHandlerImpl implements ValueListHandler


if ((adapterType & ValueListAdapter.DO_PAGE) == ValueListAdapter.DO_PAGE)
         {

            if (valueList.getValueListInfo() != null && valueList.getList() != null
                  && valueList.getValueListInfo().getPagingNumberPer() < valueList.getValueListInfo().getTotalNumberOfEntries())
            {
               int start = (valueList.getValueListInfo().getPagingPage() - 1) * valueList.getValueListInfo().getPagingNumberPer();
               int end = Math.min(start + valueList.getValueListInfo().getPagingNumberPer(), valueList.getList().size());
               valueList = new DefaultListBackedValueList(valueList.getList().subList(start, end), valueList.getValueListInfo());
               if (LOGGER.isDebugEnabled())
               {
                  LOGGER.debug("The ValueList was paged by post process.");
               }
            }
         }
