containers

I'd like to write a function template that operates on a container of strings, for example a std::vector . I'd like to support both CString and std::wstring with the same template function. The problem is that CString and wstring have different interfaces, for example to get the "length" of a CString , you call the GetLength() method, instead for wstring you call size() or length() . If we had a "static if" feature in C++, I could write something like: template <typename ContainerOfStrings> void DoSomething(const ContainerOfStrings& strings) { for (const auto & s : strings) { static_if(strings

I'm writing an own container class and have run into a problem I can't get my head around. Here's the bare-bone sample that shows the problem. It consists of a container class and two test classes: one test class using a std:vector which compiles nicely and the second test class which tries to use my own container class in exact the same way but fails miserably to compile. #include <vector> #include <algorithm> #include <iterator> using namespace std; template <typename T> class MyContainer { public: class iterator { public: typedef iterator self_type; inline iterator() { } }; class const

NOTE: Am super new to both Windows and Docker The tutorial I've been using says that they are under /var/lib/docker/containers if we're using Linux, but I can't seem to find that on my Windows machine. Thanks! christian Enter docker-machine with docker-machine ssh there you should find your containers. sudo ls /var/lib/docker/containers Things might have changed with Windows 10 Anniversary Update. I installed Docker from source here ( https://master.dockerproject.org/windows/amd64/docker-1.13.0-dev.zip ) as described here: https://msdn.microsoft.com/en-us/virtualization/windowscontainers/quick

Could anyone please give me a brief full list of containers in Java? Some of the ones I know are Array, Arraylist, Hashtable, HashMap, HashSet, Node, NodeList, TreeNode, and TreeMap. essentially, all the docs about java "containers", or better known as collections, is here , with the most useful page being this one , brief list here . There are other implementations of the collections framework, like the fastutils framework that gives better performance if you knew the type you were going to use. Also Gnu Trove is another one similar to fastutils. dfa You can check at official Sun tutorial .

What exactly does Docker do with Union File system (like AUFS) to create the containers ? If Docker had to use a regular file system instead of a union file system what will be the disadvantages ? I am looking for specific technical details/internals and not a high level answer. It is used to: avoid duplicating a complete set of files each time you run an image as a new container isolate changes to a container filesystem in its own layer, allowing for that same container to be restarted from a known content (since the layer with the changes will have been dismissed when the container is

I'd better ask the question by example. Let's say I have UserControl and Window which uses this control. I would like to design this control (named MyControl) in such way (this is sci-fi syntax!): <Grid> <Button>Just a button</Button> <PlaceHolder Name="place_holder/> </Grid> and use in such ways when designing my Window: <MyControl/> or <MyControl> <place_holder> <Button>Button 1</Button> </place_holder> </MyControl> or <MyControl> <place_holder> <Button>Button 1</Button> <Button>Button 2</Button> </place_holder> </MyControl> Of course I would like to have ability to add even more elements to

This is not exactly a technical question, since I know C kind of enough to do the things I need to (I mean, in terms of not 'letting the language get in your way'), so this question is basically a 'what direction to take' question. Situation is: I am currently taking an advanced algorithms course, and for the sake of 'growing up as programmers', I am required to use pure C to implement the practical assignments (it works well: pretty much any small mistake you make actually forces you to understand completely what you're doing in order to fix it). In the course of implementing, I obviously run
