lazy-loading

I found Fedor's code here and implemented it into my project. The only difference is that my application does not have a list view, rather, I am accessing 1 image at a time from the server. When the activity launches, i call "DisplayImage(...)" to show the first picture. Then there are 2 buttons (previous/next) that when clicked, they call "DisplayImage(...)". It works fine for a little while, but then I get an Out of Memory error. At the top of his code, he comments that you may want to use SoftReference. I am assuming that would fix my problem, right? I played around with it a bit but when I

I am trying to add states to my app dynamically and tried using ui-router. I tried following this thread. AngularJS - UI-router - How to configure dynamic views In my case, there are some existant states already and i need to append to that list with the dynamic states being read from json For some reason, i get injector error on $urlRouterProvider when trying to use for deferIntercept() method. In my case, i am using angular 1.3 and the ui-router version is 0.2.10. I see that you can create states synamically. But can we add to the existing list of states already configured statically Here is

I want to do some stuff. I wanna do lazy loading in ListView . My ListView contain more than 10,000 data & only in TextView . so i can't load all that data in first time when i launch list activity. it's not efficient so i can load first 20 or 30 items in list. further the rows of the ListView are loaded when I scroll over them. so when i reach at last index of ListView on last index, i will put progressbar n it will note that the new data are loaded, so at that time new data will be load with last + 1 index. How can i do this? Andro Selva You can achieve this by using endless Adapter

This question already has an answer here: How to fix org.hibernate.LazyInitializationException - could not initialize proxy - no Session 18 answers Have following query to the database: Session session = EmployeesDAO.getSessionFactory().getCurrentSession(); List<Employee> employees = new ArrayList<Employee>(); try { session.beginTransaction(); String hqlQuery = "from Employee emp " + "left join fetch emp.employeesOffices employeesOffice " + "left join fetch employeesOffice.office employeesOfficeOffice " + "left join fetch employeesOfficeOffice.company " + "left join fetch emp.address

In the context of ORM / Lazy loading of entities, my understanding of the term "Hydration" is as follows: "Hydrating" describes the process of populating some or all of the previously unpopulated attributes of an entity fetched using lazy loading. Eg: class Author is loaded from the database: @Entity class Author { @Id long id; List<Book> books; } Initially, the books collection is not populated. It is my understanding that the process of loading the books collection from the database is referred to as "Hydrating" the collection. Is this definition correct, and is the term common place? Is

I'm running into LazyLoading exceptions like the most people who try remoting with an ORM. In most cases switching to eager fetching solves the problem (Lazy Loading / Non atomic queries / Thread safety / n+1 problem ...). But eager fetching has also disadvantages if you are dealing with a really big object graph. Loading the whole object graph isn't needed in the most use-cases. It feels bad to load more data then needed (or load them from the db and extract the needed subset). So what alternative ways are there to solve this kind of problem (at runtime)? I've seen: Inject a data access

How do I implement progressive loading of content as you scroll down the page? Otherwise 1000 images would load at the same time. EpokK Use infinite scrolling directive. ngInfiniteScroll DEMO HTML <div ng-app='myApp' ng-controller='DemoController'> <div infinite-scroll='loadMore()' infinite-scroll-distance='2'> <img ng-repeat='image in images' ng-src='http://placehold.it/225x250&text={{image}}'> </div> </div> JS var myApp = angular.module('myApp', ['infinite-scroll']); myApp.controller('DemoController', function($scope) { $scope.images = [1, 2, 3, 4, 5, 6, 7, 8]; $scope.loadMore = function() {

In .NET 4 the following snippet with a cached property can also be written using the System.Lazy<T> class. I measured the performance of both approaches and it's pretty much the same. Is there any real benefit or magic for why I should use one over the other? Cached Property public static class Brushes { private static LinearGradientBrush _myBrush; public static LinearGradientBrush MyBrush { get { if (_myBrush == null) { var linearGradientBrush = new LinearGradientBrush { ...}; linearGradientBrush.GradientStops.Add( ... ); linearGradientBrush.GradientStops.Add( ... ); _myBrush =
