WithValue () ,context.WithCancel (), WithTimeout (), WithDeadline () are derived context from root context which can be further divide. An example of each can make it clear so ast to what is the correct use context.
You can create your own Context by sub-classing javax.naming.InitialContext and implementing only a small subset of methods, typically the bind and the lookup methods. Then you can create your data source and bind it to your initial context to a specific key. After this you are ready to go and query from any place your JNDI context in your stand-alone Java programme. This is the code you can ...
2 If you are inside of Spring bean (in this case @Controller bean) you shouldn't use Spring context instance at all. Just autowire className bean directly. BTW, avoid using field injection as it's considered as bad practice.
HTTP context accessor Finally, you can use the IHttpContextAccessor helper service to get the HTTP context in any class that is managed by the ASP.NET Core dependency injection system.
Documentation on the nature of context is pretty sparse at the moment. (There is a long discussion in the Github repo about "making the concept less nebulous".) In a few places in the documentation it's referred to as a "context dictionary" or even an "execution context dictionary", but never really spelled out what that is. Apparently, the Templates Reference is considered to be documentation ...
In Android programming, what exactly is a Context class and what is it used for? I read about it on the developer site, but I am unable to understand it clearly.
Creating context managers is done by implementing __enter__() and __exit__() in a normal class. __enter__() tells what to do when a context manager starts and __exit__() when a context manager exists (giving the exception to the __exit__() method if an exception occurred) A shortcut for creating context managers can be found in contextlib.
context defines either a path to a directory containing a Dockerfile, or a URL to a git repository. In your case, . is a relative path representing the current directory where you run docker-compose command and where Compose can find a Dockerfile (and obviously also the docker-compose.yaml file).
The nullable warnings context specifies the warnings generated by the compiler using its flow analysis. The nullable annotation context and nullable warning context can be set for a project using the Nullable element in your .csproj file. This element configures how the compiler interprets the nullability of types and what warnings are generated.
And use context.TODO() in other places? Can anyone help with this? Trying to check to see which param should I use context.TODO() or context.Background().
