builder

I don't understand what is exactly a builder in CDT, and what is the relationship with the "C/C++ Build" content. I set up SCons in the "C/C++ Build" confuguration. It does work : I made two configurations (release and debug), and my SCons scripts are launched. But as I try now to debug, I am studying these Builders stauuf (I am discovering Eclipse...). The documentation is not clear at all about this point. Thanks for help. I'm not exactly sure what your problem is, but I'll try to explain how builders work. Any Eclipse project has zero or more builders, and they are invoked (in order) when

Does anyone have any suggestions on how to make a AdWhirl banner in interface builder? Right now I use this code to make a banner: AdWhirlView *awView = [AdWhirlView requestAdWhirlViewWithDelegate:self]; [self.view addSubview:awView]; awView.frame = CGRectMake(0, 361, kAdWhirlViewWidth, kAdWhirlViewHeight); I've tried to make a UIView and making an IBOutlet to it and making it's class a AdWhirlView but I can't seem to get it right... Thanks Here is the code that I use with IB: In SecondViewController.h @interface SecondViewController : UIViewController <AdWhirlDelegate> { IBOutlet AdWhirlView

一、什么是缓存？ 根据科普中国的定义，缓存就是数据交换的缓冲区（称作Cache），当某一硬件要读取数据时，会首先从缓存中查找需要的数据，如果找到了则直接执行，找不到的话则从内存中找。由于缓存的运行速度比内存快得多，故缓存的作用就是帮助硬件更快地运行。 在这里，我们借用了硬件缓存的概念，当在Java程序中计算或查询数据的代价很高，并且对同样的计算或查询条件需要不止一次获取数据的时候，就应当考虑使用缓存。换句话说，缓存就是以空间换时间，大部分应用在各种IO，数据库查询等耗时较长的应用当中。 二、缓存原理 当获取数据时，程序将先从一个存储在内存中的数据结构中获取数据。如果数据不存在，则在磁盘或者数据库中获取数据并存入到数据结构当中。之后程序需要再次获取数据时，则会先查询这个数据结构。从内存中获取数据时间明显小于通过IO获取数据，这个数据结构就是缓存的实现。 这里引入一个概念，缓存命中率：从缓存中获取到数据的次数/全部查询次数，命中率越高说明这个缓存的效率好。由于机器内存的限制，缓存一般只能占据有限的内存大小，缓存需要不定期的删除一部分数据，从而保证不会占据大量内存导致机器崩溃。 如何提高命中率呢？那就得从删除一部分数据着手了。目前有三种删除数据的方式，分别是：FIFO（先进先出）、LFU（定期淘汰最少使用次数）、LRU（淘汰最长时间未被使用）。 三、GuavaCache工作方式

what I would like to know if it's possible to build a view and its correspondent xib file. Then, in a generic controller, load this view programmatically and add as a subview to the current view. This subview should act as a generic info box which can be loaded by many controller. thanks Leonardo Leonardo I found solution myself, after looking at some stackoverflow thread. So I would like to share what I found and see if it's an acceptable solution. Basically this is what I did: create a MyView.m view file with all my required IBOutlet build a MyView.xib view in interface builder, leaving

I'm attempting to implement a new collection type which follows the same idioms as the standard library, but am having trouble figuring out how to handle the Builder mechanics. I've read through the excellent "Architecture of Scala Collections" doc page , but it doesn't cover my situation. Here's a simplified version of what I'm trying to do: import scala.collection.TraversableLike import scala.concurrent.Future trait AsyncMap[A, +B] extends Traversable[(A, B)] with TraversableLike[(A, B), AsyncMap[A, B]] { def empty: AsyncMap[A, B] // This is the main difference from scala.collection.Map (an
