get

I'm using fedor's lazy loading list implementation in my test application where I can clear the cache with a single button click. How can I get the cache size of the loaded images in the listview and clear the cache programmatically? Here is the code for saving the cached images: public ImageLoader(Context context){ //Make the background thead low priority. This way it will not affect the UI performance. photoLoaderThread.setPriority(Thread.NORM_PRIORITY-1); mAssetManager = context.getAssets(); //Find the dir to save cached images if (android.os.Environment.getExternalStorageState().equals

关于Hibernate的load和get方法的区别，网上一抓一大片。不过，也许是版本的不同，感觉网上的文章有其谬误。况且，说两者区别的文章一大片，但几近没有文章谈及何时使用这两方法合适。 网上流传较广的说法之一是：load比get效率高。 理由是：load比较聪明，会先从1、2级缓存中找数据，找不到再从数据库中查询；而get则是个笨蛋，不管三七二十一，直接查数据库。 也许老版本是这样，实际上，我用Hibernate3.6测试发现，get也会从缓存中找数据。所以，在查询方面，我认为两者间的效率并无甚差异——想想也该明白，如果load真比get全方位的优胜，那get还有存在的意义么？早就被Hibernate开发组的人淘汰了。 那么，load和get到底有什么区别——或者说，他们各自应用在什么地方？ 我觉得，他们俩之间的关系就像是单例模式中的懒汉式和饿汉式——如果要取的数据不多，并且确定一定会用到，那么直接拿过来就好；反过来，如果要查的数据不一定被用到，而且数据量较大，耗费资源较多，那我们就应该使用load延迟加载，即在真正要用的时候再来查询数据。 网上的文章大多都列了好多load和get的不同之处的条目，这里就不再赘述了——优秀的程序员从不干重复低价值的劳动，嘿嘿。 来源： oschina 链接： https://my.oschina.net/u/1379006/blog/190094

Using jQuery I would like to loop through an array of links and load the contents of each link into a DIV after a set interval. For example, if I have my parent page "parent.html" and an array of links - "test1.html, test2.html and test3.html" I would like to initially load test1.html into a div within parent.html and then after a set interval replace test1.html with test2.html and then test3.html repeating the process indefinitely. I would really appreciate if someone could help me out. I have tried using .get() and also setTimeout() but just don't have the expertise and experience to put

I'm developing an iOS application to play private Vimeo videos. Private videos are given privacy of hiding videos from Vimeo website and given domains so that those videos only will be bought and played in my websites. I have Vimeo PRO account. I am using VIMNetworking SDK and make authentication in didFinishLaunchingWithOptions() by using client details I got creating app at https://developer.vimeo.com/apps . Now I have to make API request to get direct video urls. I don't know how to achieve this. Vimeo doesn't give documentation for objective-c. By using below code I get public video

I have a very simple ajax GET request in jquery that works just fine on my local test server. If I move the web page to a hosted server (GoDaddy) along with the php service it fails with a textStatus = "error" and errorThrown = "" . Chrome displays net::ERR_EMPTY_RESPONSE. This all happens within 1 second so it's not a timeout issue. If I truncate the number of records so the json returned is less than 1MB it works fine. If I call the server code from GoDaddy webpage to my local server for all records (1.8MB) all is fine too. The good returns from either site will complete in less than a

I'm calling a jQuery "GET" on the test.php file code below. I'm trying to get the script to pop a "Save As" dialog on the resulting test.ini file to allow it to be saved locally. However, although I can echo the result back to the jQuery fine, I can't seem to pop the "save as" dialog. Update: Thanks to the solutions below, I just changed my $.get to a window.location.replace. $('#test').click( function() { //$.get('<?php echo get_bloginfo('template_directory') ?>/test.php'); window.location.replace("<?php echo get_bloginfo('template_directory') ?>/test.php"); } ); Jimmy Baker You can't get an
