containers

问题 When I pull an image from public elasticsearch repo, spawning container with that pulled image is working fine for me with no permission issues. docker pull elasticsearch docker run -d elasticsearch But when I spawn a container with the Dockerfile which is available there with the public repo gives me permission issues. I do have a same directory structure as public repo. myfolder/Dockerfile myfolder/docker-entrypoint.sh myfolder/config/elasticsearch.yml myfolder/config/logging.yml https:/

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I'm looking for a comprehensive summary/reference of important properties of the various C++11 standard containers and container adapters (optionally also including boost/Qt), but indexed by those properties rather than the usual per container documentation (more on that below). The properties I have in mind

问题 I am looking for a container which provides std::map like interface but maintains the order in which elements are inserted. Since there will not be too many elements in the map, the lookup performance is not a big issue. Will boost::unordered_map work in this case? i.e. does it maintain the order of insertion. I am new to boost library and hence want to know what exactly meant by 'unordered' ? 回答1: unordered_map doesn't maintain the order of insertion. Unordered in this case means that the

问题 If I have a class (that mimic some of STL's container) like this: class Elem { public: void prepare(); // do something on *this // ... }; class Selector { public: typedef vector<Elem *> container_type; typedef container_type::iterator iterator; iterator begin() { return cont_.begin(); } iterator end() { return cont_.end(); } void check_all(); private: prepare_elem(Elem *p); // do something on 'p' container_type cont_; }; If I want to call prepare() for all elements in 'cont_', I could make

问题 I am trying to apply Lazy Load plugin to multiple containers. I found this similar question: Lazy Load on MULTIPLE horizontal containers. this is my attempt: http://jsfiddle.net/BAFMC/ $(".p_outer_content").each(function() { var tthis = $(this); $(this).find('img').lazyload({ container: tthis }); });​ But I have the same problem as the question mentioned, which is that Lazy load only applies to the last container (.p_outer_content) (which is the third one in the fiddle). Does anyone know how

问题 I came up with the following: template <typename T> inline void printcontainer( std::vector<T> container ) { for( auto it = container.begin(); it != container.end(); it++ ) { std::cout << *it << std::endl; } } int _tmain(int argc, _TCHAR* argv[]) { std::vector<int> v; v.push_back(5); v.push_back(4); v.push_back(3); printcontainer(v); return 0; } (Sorry for the push_backs , visual studio doesn't accept initializer lists...ugh!!) now this function is limited to std::vector , how can I make it

问题 I want to use a structure in which I insert integers, and then can ask if (container.contains(3)) { /**/ } There has to be something like this. 回答1: You can use std::vector . std::vector<int> myVec; myVec.push_back(3); if (std::find(myVec.begin(), myVec.end(), 3) != myVec.end()) { // do your stuff } You can even make a little helper function: template <class T> bool contains(const std::vector<T> &vec, const T &value) { return std::find(vec.begin(), vec.end(), value) != vec.end(); } Here is

问题 I went and created a tab containing a good amount of controls, most of which are contained within what I'll just call the top-level group box. Now I decide I'd like the text of the top-level group box to be bold, but nothing else. When I set the top-level group box's font to bold, however, all of the controls contained within it become bolded as well, which is what I don't want. I can set each individual control's bold property to false, but it seems like there should be an easier way to do

问题 I'm experienced with C++, but a little new to C#. When you add objects to a container, are they passed by reference or by value? That is, if I do this: myClass m = new myClass(0); //Assume the class just holds an int List<myClass> myList = new List<myClass>(1); myList.Add(m); myList[0] += 1; Console.WriteLine(m); Console.WriteLine(myList[0]); Will the result be: 0 1 or will it be 1 1 ? If the former, then how can get I make it do the latter? My first instinct was to do something like myClass
