Traits solution. Generalize not more than needed, and not less. In some cases that solution might not be enough as it will match any template with such signature (e.g. shared_ptr), in which case you could make use of type_traits, very much like duck-typing (templates are duck typed in general). #include <type_traits> // Helper to determine … Read more
As you have already figured out, Dependency Injection (DI) itself is only a collection of patterns and techniques. At the root of the application we wire up all necessary object graphs. This place is called the Composition Root, and we can use a DI Container to do this wiring for us, or we can do … Read more
You can specify the arguments directly in your docker-compose file: node1: build: context: node1 args: ADMIN_USERNNAME: weblogic1 ADMIN_PASSWORD: weblogic1 ADMIN_NAME: admin1 image: node1 container_name: node1 See a full example: MWE The official docs (legacy v3 here) have all detail.
This isn’t pretty, but it seems to work: public static class GroupGenerator { public static T Create<T>(IEnumerable<T> items) where T : class { return (T)Activator.CreateInstance(Cache<T>.Type, items); } private static class Cache<T> where T : class { internal static readonly Type Type; static Cache() { if (!typeof(T).IsInterface) { throw new InvalidOperationException(typeof(T).Name + ” is not an … Read more
Moron/Aryabhatta is correct, but a little more detail may be helpful. Queue and stack are higher level containers than deque, vector, or list. By this, I mean that you can build a queue or stack out of the lower level containers. For example: std::stack<int, std::deque<int> > s; std::queue<double, std::list<double> > q; Will build a stack … Read more
Firstly you need to install a SSH server in the images you wish to ssh-into. You can use a base image for all your container with the ssh server installed. Then you only have to run each container mapping the ssh port (default 22) to one to the host’s ports (Remote Server in your image), … Read more
After many hours trying it, I finally solved it with this Dockerfile Note I am using python 3.7, Django 3.0, Oracle Database 12c and Pipenv for package management FROM python:3.7.5-slim-buster # Installing Oracle instant client WORKDIR /opt/oracle RUN apt-get update && apt-get install -y libaio1 wget unzip \ && wget https://download.oracle.com/otn_software/linux/instantclient/instantclient-basiclite-linuxx64.zip \ && unzip instantclient-basiclite-linuxx64.zip … Read more
I found solution for both problems: inotify -> just edit package.json in “scripts” section this line: “start”: “ng serve –host 0.0.0.0 –poll”, required only for Windows host, hot reload -> add expose 49153 in Dockerfile and ports – ‘49153:49153’ in docker-compose.yml like @kstromeiraos mentioned.
You might want to take a look at the Wintellect Power Collections. It is available on CodePlex and contains quite a few collections that are very helpful. The OrderedBag collection in the project is exactly what you are looking for. It essentially uses a red-black tree to provide a pretty efficient sort.
A picture is worth a thousand words. It’s available from nolyc, the informative bot of ##C++ on Freenode, using the command “container choice” or “containerchoice”. The link to this picture you receive in response is hosted at adrinael.net, which suggests we should thank Adrinael, member of Freenode’s ##C++ community.
