Lucene-2.2.0 源代码阅读学习(30)

关于Query的学习。主要使用TermQuery和BooleanQuery，它们是最最基础的Query。我感觉Query的灵活性太大了，这就使得它那么地具有魅力。当用户提交了检索关键字以后，首先就是要根据这个关键字进行分析，因为不同的用户提交的关键词具有不同的特点，所以使用不同方式来构造Query是极其关键的，从而使提供的检索服务最大程度地满足用户的意愿。先看看Query抽象类的继承关系，如图所示：最简单最基础的就是构造一个TermQuery，根据词条本身

怎么配置怎及SVN服务器

我们学习SVN的朋友都知道SVN的好处之多，其他的也就不用多说了，当我们的项目做到一定规模时，多人开发甚至异地多人协作开发时，可以为你的团队省去很多麻烦。可能很多人都用过SVN的客户端工具，如TortoiseSVN或者是Eclipse中的插件，网上有很多开源项目，或者很多源代码，都会用这种方式发布，稍有关注一下技术的很多时候都会下载别人的源程序结合自已的项目开发或者是学习，比如去GoogleCode有很多。我们只用客户端去连接SVN的服务器，之后更新代码副

listView 添加多个不同的adapter

有时候我们想在listView上分类，或者呢有时候一行显示两列内容，有时候需要三列内容，那怎么实现呢，这里呢就要使用Java代码classSection{Stringcaption;Adapteradapter;Section(Stringcaption,Adapteradapter){this.caption=caption;this.adapter=adapter;}}自定义一个类，这个类呢包含多个adapter就可以了，想用那种就用那种。Java代码

基于DirectShow/DES的MPEG-2音视频编辑软件的实

引言1994年欧洲制定的数字视频广播（DVB）标准和1996年美国联邦通信委员会（FCC）的先进电视制式委员会（ATSC）地面广播电视标准，在视频部分都采用了MPEG-2标准。我国的CATV数字网，也采用DVB标准。MPEG-2标准的出现，大大推动了数字视频业务的发展。越来越多的节目交换是以MPEG-2压缩方式进行的，使演播室制作涉及大量对MPEG编码压缩节目的处理，如非线性编辑涉及的不同节目间的切换、剪切和串编、在画面上加字幕、台标、实现淡入淡出等。其中
