Thread-safe cache of one object in java

北战南征 提交于 2019-11-27 17:31:19
let's say we have a CountryList object in our application that should return the list of countries. The loading of countries is a heavy operation, so the list should be cached. Additional requirements: CountryList should be thread-safe CountryList should load lazy (only on demand) CountryList should support the invalidation of the cache CountryList should be optimized considering that the cache will be invalidated very rarely I came up with the following solution: public class CountryList { private static final Object ONE = new Integer(1); // MapMaker is from Google Collections Library private

Stop Activerecord from loading Blob column

女生的网名这么多〃 提交于 2019-11-27 16:21:04
问题 How can I tell Activerecord to not load blob columns unless explicitly asked for? There are some pretty large blobs in my legacy DB that must be excluded for 'normal' Objects. 回答1: I just ran into this using rail 3. Fortunately it wasn't that difficult to solve. I set a default_scope that removed the particular columns I didn't want from the result. For example, in the model I had there was an xml text field that could be quite long that wasn't used in most views. default_scope select((column

How to Lazy load non-angular JavaScript files using AngularJS?

痞子三分冷 提交于 2019-11-27 16:08:47
问题 Is it possible to load plain old JS or AMD modules from an Angular Controller? I have previously used RequireJS for this. I have used AngularJS and RequireJS on a fairly large project before. I am working on a new project based on the MEAN Stack seed, and this does not use requireJS. I am not entirely clear, but Angular has a system for loading modules -- can I load a particular piece of javascript from within my angular controller? Is there a way to modify my module() declaration to include

AngularJS- Dynamic Loading of script files using LazyLoad- Webpack

杀马特。学长 韩版系。学妹 提交于 2019-11-27 16:00:30
Right now in my index.html page I have links to two CDN files one being a JS and the other a CSS file. i.e. in the the bottom of my body https://somedomain.com/files/js/js.min.js and in the head https://somedomain.com/files/css/css.min.css But right now they aren't needed on my homepage but just in one particular route. So I was looking into how I can lazy load these CDN resources when that routes gets hit i.e. /profile and only then ? These aren't installed via bower or npm but just loaded via CDN url for example jquery. How in Angular 1 and Webpack can I lazy load that based on a route ?

Doctrine2 (Doctrine 2.1) eager loading in Symfony2

我怕爱的太早我们不能终老 提交于 2019-11-27 15:50:11
问题 Let's say I have two entities in my Symfony2 project : Category and Article (a category having many articles). In my CategoryRepository , I have this method: findAllDummy(){ return $this->createQueryBuilder('c') ->leftJoin('c.Articles a') ->getQuery()->getResult(); } If I remember well, in Symfony1.4 (and the corresponding version of Doctrine), the returned objects would have their 'articles' attribute filled by the corresponding Article objects. Now, in Symfony2, Proxy objects are returned.

Issue with Casting proxies when using NHibernate table per subclass inheritance strategy

[亡魂溺海] 提交于 2019-11-27 14:57:51
问题 I have got an abstract base class and inherited poco entities. I am using table per subclass inheritance with fluent nhibernate 1.1 automapping. The class inheritance looks like follows Node (abstract class) Place : Node Asset : Node Node class is basically a tree structure. public abstract class Node { public virtual int Id { get; set; } public virtual Node ParentNode { get; set; } public virtual ICollection<Node> ChildNodes { get; set; } } Now the problem is when I get an object of Asset

Combining jQuery Isotope and Lazy Load

落爺英雄遲暮 提交于 2019-11-27 12:29:14
Have started a project using jQuery Isotope. Initially integrated with Infinite scroll, but thought it was a little clunky. Was hoping to replace Infinite Scroll with Lazy Load, and wondered if anyone has had any luck combining the two. Any tips to get them to play nice would be great. Thanks a mill If you want to use isotope's sorting/filtering functions, you will need to set the failure_limit of lazyload and trigger the event with isotope's onLayout callback. jQuery(document).ready(function($) { var $win = $(window), $con = $('#container'), $imgs = $("img.lazy"); $con.isotope({ onLayout:

Post-loading : check if an image is in the browser cache

独自空忆成欢 提交于 2019-11-27 12:23:27
Short version question : Is there navigator.mozIsLocallyAvailable equivalent function that works on all browsers, or an alternative? Long version :) Hi, Here is my situation : I want to implement an HtmlHelper extension for asp.net MVC that handle image post-loading easily (using jQuery). So i render the page with empty image sources with the source specified in the "alt" attribute. I insert image sources after the "window.onload" event, and it works great. I did something like this : $(window).bind('load', function() { var plImages = $(".postLoad"); plImages.each(function() { $(this).attr(

Django lazy QuerySet and pagination

白昼怎懂夜的黑 提交于 2019-11-27 11:43:01
I read here that Django querysets are lazy, it won't be evaluated until it is actually printed. I have made a simple pagination using the django's built-in pagination. I didn't realize there were apps already such as "django-pagination", and "django-endless" which does that job for. Anyway I wonder whether the QuerySet is still lazy when I for example do this entries = Entry.objects.filter(...) paginator = Paginator(entries, 10) output = paginator.page(page) return HttpResponse(output) And this part is called every time I want to get whatever page I currently I want to view. I need to know
