lazy-loading

问题 I am having problems with adding new states to the runtime phase of my app using ' UI-Router-Extras '. I have been trying for quite some time now to get new states attached and loaded AFTER a user has successfully authenticated using the ' UI-Router-Extras ' plugin 'ui-router-extras' Here is a reference to the 'UI-Router-Extras' Examples for the FutureState documentation that i'm using, but I feel like maybe my scenario is either slightly different that what's shown or I'm missing something

问题 I wrote a little "lazy vector" class (or, delayed vector) which is supposed to look like a std::vector and usable wherever a std::vector is used, but it loads its elements "lazily", i.e. it will load element n (and possibly a few more) from disk whenever someone accesses element n . (The reason is that in my app, not all elements fit into memory.) Here is this LazyVector class, but there is a problem with const member functions that use such a vector, see below. template<class T> class

问题 I'm trying to use the canLoad function with routes, but it doesn't seem to work. I don't know why, maybe you can't use it with canActivate or something, but since I don't know, I thought someone would here. The code runs, when serving with aot compilation I get this : chunk {admin.module} admin.module.chunk.js, admin.module.chunk.js.map () 28 kB {main} {pilotage.module} {suiviprod.module} chunk {inline} inline.bundle.js, inline.bundle.js.map (inline) 5.83 kB [entry] chunk {main} main.bundle

问题 I was reading about a feature of an ORM called lazy loading, which, it said, means that larger columns are only loaded when the application actually needs them. How would an ORM decide what a "large column" is - would this be, for example, a blob column that can contain a lot of data compared to, say, an unsigned integer column? And when it says it lazy loads the column, does this mean when you run a query, you might not get results for some of the larger columns when you expect to? 回答1: In

问题 With reference to the suggestion given in the post here i tried implementing lazy loading with live scrolling to handle large data sets,but live scrolling doesn't happen when both rows and scrollRows attributes of datatable are used.If i remove rows attribute then no records would be displayed.Here is my code snippet that i tried.Can someone please help me out if i am doing anything wrong. JSF code snippet <p:dataTable id="arcRecList" var="data" value="#{archivedRecordBean.archModel}" lazy=

问题 I've been seeing some strange behavior in NHibernate regarding lazy loading and several filters that are set up in my application. It seems that if I filter on a lazy-loaded association, that association only has the members that apply to the filter for the remainder of the NHibernate session. I know that sounds confusing, so I've reproduced it in a fairly simple example. I've made a "PetFun" web application that uses Spring MVC 1.3.2 and NHibernate 3.3.3.4001. This dummy app just has a

问题 I have different components and routes based on roles. Now i have defined routes as for certain components as below Login Module path: '', loadChildren:'app/login/login.module#LoginModule'; Register Module path:'', loadChildren: 'app/register/register.module#LoginModule' Dashboard Module path:'' loadChildren:'app/dashboard/dashboard.module#dashboardModule' User Profile Module path:'' loadChildren:'app/user-profile/user-profile.module#UserProfileModule' Now whenever I navigate to login or

问题 Initially I am populating 100 rows in Data grid, when user scroll the grid rows, I want to populate another 100 rows. I am using wpf data grid, I have not found any event of data grid that I can catch to accomplish this task. Then I have used scroll viewer control and try to catch change event where I know that my scroll viewer reach at end , then I will load another rows in data grid. <ScrollViewer Name="svDataGrid" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled"

问题 I am planning the implementation of an Inheritance Mapper pattern for an application component http://martinfowler.com/eaaCatalog/inheritanceMappers.html One feature it needs to have is for a domain object to reference a large list of aggreageted items (10,000 other domain objects) So I need some kind of lazy loading collection to be passed out of the aggregate root domain object to other domain objects. To keep my (php) model scripts organised i am storing them in two folders: MyComponent\
