NHibernate: Simplest way to return an object with paged children collection?

由 坚强是说给别人听的谎言 提交于 2019-12-10 10:12:53
问题 I want to return one Parent object with the children collection eagerly loaded with the requested page (subset) of children objects. What's the best way to achieve this? Filters? Is is possible with an ICriteria query? I'm using .SetFirstResult() and .SetMaxResults() to do paging for collections of aggregate root results, but is it possible to utilize this withing the aggregate root to select the page of children results? Something along these lines: public class Parent{ int Id; IList<Child>

Freebase “Key cursor is a reserved word”

由 前提是你 提交于 2019-12-10 10:04:41
问题 Following the Freebase docs on Envelope Parameters, running { "cursor":true, "query":[{ "type":"/music/album", "artist":"The Police", "name":null, "limit":10 }] }​ results in error "Key cursor is a reserved word" as @Domenic notes. What's going wrong? Edit 1 So this query without a cursor works but this one doesn't because cursor was a variable name not a string enclosed in quotes. As a user it makes sense to type the broken version of "cursor" because the read parameter type table has both

Android - How do you efficiently load a large amount of text in a TextView?

由 我是研究僧i 提交于 2019-12-10 01:02:38
问题 I'm writing an Android app that reads a single text file and display it on a TextView . What I'm doing right now is read the whole file into a String (using BufferedReader and StringBuilder ) and display it on a TextView using setText(string) . A 700KB text file can take about 2 to 3 seconds before it is being displayed on the screen. But I've used some other ebook readers on the market and they can display the same text almost instantly. Anyone know how I can achieve this? Thanks you. Edit :

Virtual Memory and Physical Memory

问题 I am studying the concept of Memory Management Unit(MMU) from the book titled "Operating System Concepts" - by Abraham Silberschatz and Galvin. Though things were fine till chapter 8. As soon I started with chapter 9, things started messing up. I am not clear about what my virtual memory is? Also, physical and logical addresses seems to be confusing now? Does it(virtual memory) exists in real or not? As per my understanding of now, the RAM of my system is what I call Physical(or main) Memory.

UIScrollView - (bounces = NO) seems to override (pagingEnabled = YES)

由 隐身守侯 提交于 2019-12-09 06:19:01
问题 I have a UIScrollView with paging in it (so the typical model with a UIPageControl and dragging/flicking left and right between pages), and I've got that working fine. The weird thing is that when I wanted to get rid of bouncing (so that you can't see black behind the UI on the left and right sides), suddenly paging no longer works. In other words, when: scrollView.pagingEnabled = YES; scrollView.bounces = YES; Everything works fine, except I don't like the bouncing at page(0) and page(length

Get the total number of records when doing pagination

由 被刻印的时光 ゝ 提交于 2019-12-09 02:36:48
问题 To get a page from a database I have to execute something like this: var cs = ( from x in base.EntityDataContext.Corporates select x ).Skip( 10 ).Take( 10 ); This will skip the first 10 rows and will select the next 10. How can I know how many rows would result because of the query without pagination? I do not want to run another query to get the count. 回答1: To get the total number of records before skip/take you have to run a separate query. Getting the actual number returned would use Count
