JavaFX TableView中的快速过滤 [英] Fast filtering in javafx tableview

问题描述

我需要在Javafx tableview中实现具有大数据(大约100,000个)的过滤器，

I need to implement a filter in javafx tableview with huge data (around 100,000 ),

我已经尝试过本教程.它可以工作，但与swing 排序和过滤，

I have tried this tutorial. It works but filtering is really slow as compared to swing sorting and filtering, code.

任何人都可以帮助我提高速度.

Can anyone help me to increase speed.

现在发生的事情是，当我键入textproperty change并启动了filterdata，但是速度很慢时，我需要一些可以快速显示输入结果的过滤器结果.

What is happening right now is as I type textproperty change fire up and filterdata but it is slow, I need something which shows filter result with typing quickly as happening in swing.

提前谢谢.

p.s我也看过此.

推荐答案

您可以使用FilteredList

You may use FilteredList

ObservableList<YourObjectClass> actualList = ...;
FilteredList<YourObjectClass> filteredList = new FilteredList<>(actualList);

TableView table = ...;
table.setItems(filteredList);

// to filter
filteredList.setPredicate(
    new Predicate<YourObjectClass>(){
        public boolean test(YourObjectClass t){
            return false; // or true
        }
    }
);

与挥杆一样快((可能快于挥杆...). (我测试了100000行)

as fast as swing, (maybe faster then swing... ). (I tested with 100000 rows)
