请求翻译一下，下边这串代码主要功能啥意思还有模糊查询和精准查询的代码谢

Question

public//列表
    Map list(BaseParam baseParam,MarketIssueParam marketIssueParam) {
        Map<String, Object> list=new HashMap<>();
        PageHelper.startPage( baseParam.getPage(),baseParam.getLimit() );
        MarketKeywordExample marketKeywordExample=new MarketKeywordExample();
        MarketKeywordExample.Criteria criteria=marketKeywordExample.createCriteria();
        criteria.andDeletedEqualTo( true );
        if ( marketIssueParam.getId()!= null ) {
            criteria.andIdEqualTo( marketIssueParam.getId() );
        }
        if ( !StringUtils.isEmpty( marketIssueParam.getClass() ) ) {
            criteria.andKeywordEqualTo( marketIssueParam.getClass() );
        }
        if ( !StringUtils.isEmpty( marketIssueParam.toString() ) ) {
            criteria.andAddTimeBetween( "" + marketIssueParam.toString() + "" );
        }

        List<MarketIssue> marketKeywords =marketIssueMapper.selectByExample( marketIssueParam );
        PageInfo pageInfo=new PageInfo();

        list.put( "total",pageInfo.getTotal() );
        list.put( "pages",pageInfo.getPages() );
        list.put( "limit",pageInfo.getPageSize() );
        list.put( "page",pageInfo.getPageNum() );
        list.put( "list",pageInfo.getList() );
        return list;

    }

这串代码应该是用来分页的吧，模糊查询和精确查询的代码，你的意思是sql语句还是Java代码，sql我知道，但是Java的还真不清楚
