java - 我想在 Java GUI 中的表过滤器之间创建 "or"关系而不是 "and"

Question

我想在这些过滤器之间创建“或”关系，而不是“与”关系，这就是它的作用。有什么办法可以做到这一点吗？

List<RowFilter<Object,Object>> filters = new ArrayList<RowFilter<Object,Object>>(8);
filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 1));
filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 2));
filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 3));
filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 4));

新代码

尝试{

         List<RowFilter<Object,Object>> filters = new ArrayList<RowFilter<Object,Object>>(8);

         List<RowFilter<Object,Object>> filter = new ArrayList<RowFilter<Object,Object>>(4);
         filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 1));
         filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 2));
         filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 3));
         filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 4));

         RowFilter<Object,Object> orFilter = RowFilter.orFilter(filter);

         filters.add(orFilter);

         String gen = (String) searchGender.getSelectedItem();
            if(gen.equals("Male"))
                gen = "M";
            else
                gen = "F";

        filters.add(RowFilter.regexFilter(gen, 5));
        filters.add(RowFilter.regexFilter(searchMailTxt.getText(), 6));
        filters.add(RowFilter.regexFilter(searchContactTxt.getText(), 7));
        filters.add(RowFilter.regexFilter(searchContactTxt.getText(), 8));

        rf = RowFilter.andFilter(filters);

    }catch(java.util.regex.PatternSyntaxException e){
        System.out.println("Unable to parse");
        return ;
    }
    sorter.setRowFilter(rf);

Answer 1

您可以使用orFilter方法:

filters.add(RowFilter.orFilter(Arrays.asList(new RowFilter[]{
  RowFilter.regexFilter(searchNameTxt.getText(), 1),
  RowFilter.regexFilter(searchNameTxt.getText(), 2),
  // .....
  })
));

但似乎regexFilter已经可以容纳多列(我认为只有其中一列需要匹配，所以这里应该有相同的结果):

filters.add(RowFilter.regexFilter(searchNameTxt.getText(), 1,2,3,4));
