containers

问题 I have two classes, one which sets up the container by registering types and one which contains a static property which I want to inject into. My issue is the property is never set by injection so when I call a method on it, the property is always null. public class ClassOne { public void Method() { Container.RegisterType<IClass, ClassImplOne>("ImplOne"); Container.RegisterType<IClass, ClassImplTwo>("ImplTwo"); } } public static class ClassTwo { [Dependency] public static IClass SomeProperty

问题 I need to have a fixed-size array of elements and to call on them functions that require to know about how they're placed in memory, in particular: functions like glVertexPointer , that needs to know where the vertices are, how distant they are one from the other and so on. In my case vertices would be members of the elements to store. to get the index of an element within this array, I'd prefer to avoid having an index field within my elements, but would rather play with pointers arithmetic

问题 I am trying to solve the following problem: Numbers are being inserted into a container. Each time a number is inserted I need to know how many elements are in the container that are greater than or equal to the current number being inserted. I believe both operations can be done in logarithmic complexity. My question: Are there standard containers in a C++ library that can solve the problem? I know that std::multiset can insert elements in logarithmic time, but how can you query it? Or

问题 Which implementations of the Servlet 3.0 specification are available (or at least in beta) besides GlassFish? 回答1: Tomcat 7.0 is on its way. It is still in development. Jetty 8 is supposed to implement Servlet 3.0, it is also still in development (check the Versions section at bottom). As far now there's only the GlassFish v3 as being a stable release. 回答2: There is Jetty 回答3: I'd also mention Resin 4.0, in development. 来源： https://stackoverflow.com/questions/1979473/available-servlet-3-0

问题 I find myself constantly writing Mutex code in order to synchronize read/write access to a std::unordered_map and other containers so that I can use them as I do java.util.concurrent containers. I was about to start writing a wrapper to encapsulate the Mutex, but I would rather use a well tested library so I don't stuff up the threading. Is there such a library? 回答1: Intel produced a library called Threading Building Blocks which has two such things: concurrent_hash_map and concurrent

问题 I'm accustomed to the existing interface of std::map . Inserting elements returns a bool describing successful insertion, as well the iterator as to where the inserted element would be. template< class P > std::pair<iterator,bool> insert( P&& value ); //(since C++11) C++17 adds what looks to be a similar call, but with different type names: insert_return_type insert(node_type&& nh); //(since C++17) I tried looking up what a node_type is, but it is primarily unspecified: template</*unspecified

问题 I know that GKE is driven by kubernetes underneath. But I don't seem to still get is that what part is taken care by GKE and what by k8s in the layering? The main purpose of both, as it appears to me is to manage containers in a cluster. Basically, I am looking for a simpler explanation with an example. 回答1: in short GKE is a managed/hosted Kubernetes (i.e. it is managed for you so you can concentrate on running your pods/containers applications) Kubernetes does handle: running pods,
