Dependency Injection (DI) in the context of using a Dependency Injection Container (DIC) can be seen as a superset of constructor injection. A DIC will typically analyze a class constructor's typehints and resolve its needs, effectively injecting the dependencies needed for the instance execution. ...

Python makes it extremely intuitive to check if a string contains a given substring. Just use the in operator: >>> "foo" in "foo.baz.bar" True Note: testing an empty string will always result in True: >>> "" in "test" True

zv will ensure the line containing the cursor is not folded. The minimum number of folds required to expose the cursor line will be opened.

docker run --add-host="app-backend:10.15.1.24" awesome-app This command adds an entry to the container's /etc/hosts file, which follows the format --add-host <name>:<address>. In this example, the name app-backend will resolve to 10.15.1.24. This is particularly useful for t...

A container will stop if no command is running on the foreground. Using the -t option will keep the container from stopping, even when detached with the -d option. docker run -t -d debian bash

docker stop mynginx Additionally, the container id can also be used to stop the container instead of its name. This will stop a running container by sending the SIGTERM signal and then the SIGKILL signal if necessary. Further, the kill command can be used to immediately send a SIGKILL or any ot...

One of the nicest features of flexbox is to allow optimally fitting containers to their parent element. Live demo. HTML: <div class="flex-container"> <div class="flex-item">1</div> <div class="flex-item">2</div> <div class=&q...

You can move a container instead of copying it: void print(const std::vector<int>& vec) { for (auto&& val : vec) { std::cout << val << ", "; } std::cout << std::endl; } int main() { // initialize vec1 with 1, 2, 3, 4 and...

Bootstrap requires a containing element to wrap site contents and house our grid system. You may choose one of two containers to use in your projects. Use .container class for a responsive fixed width container. <div class="container"> ... </div> Use .container-fluid c...

Optimizing by using the right data structures at the right time can change the time-complexity of the code. // This variant of stableUnique contains a complexity of N log(N) // N > number of elements in v // log(N) > insert complexity of std::set std::vector<std::string> stableUnique...

An example of a class that contains a parcelable class inside: public class Repository implements Parcelable { private String name; private Owner owner; private boolean isPrivate; public Repository(String name, Owner owner, boolean isPrivate) { this.name = name; ...

Enums contains only constants and can be compared directly with ==. So, only reference check is needed, no need to use .equals method. Moreover, if .equals used incorrectly, may raise the NullPointerException while that's not the case with == check. enum Day { GOOD, AVERAGE, WORST; } publi...

To check if a Dictionary has an specifique key, you can call the method ContainsKey(TKey) and provide the key of TKey type. The method returns a bool value when the key exists on the dictionary. For sample: var dictionary = new Dictionary<string, Customer>() { {"F1", new Custom...

In this example, Tags array may contain various keywords like ["promo", "sales"], so we can open this array and filter values: select ProductID, Name, Color, Size, Price, Quantity from Product CROSS APPLY OPENJSON(Data, '$.Tags') where value = 'sales' OPENJSON will op...

Dependency injection means writing classes so that they do not control their dependencies - instead, their dependencies are provided to them ("injected.") This is not the same thing as using a dependency injection framework (often called a "DI container", "IoC container&quo...

This example finds an array of approximately evenly spaced points along an entire Path. It decomposes all Path segments created with context.lineTo, context.quadraticCurveTo and/or context.bezierCurveTo into points along that Path. Usage // Path related variables var A={x:50,y:100}; var B={x:12...

# create docker container export cid=$(docker run -d --security-opt seccomp:unconfined busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done') # container is started and prints a number every second # display the output with docker logs $cid # checkpoint the cont...

MSDN: Determines whether a sequence contains a specified element by using a specified IEqualityComparer<T> List<int> numbers = new List<int> { 1, 2, 3, 4, 5 }; var result1 = numbers.Contains(4); // true var result2 = numbers.Contains(8); // false List<int> secondN...

Returns a table with the values for all row versions that were opened and closed within the specified time range defined by the two datetime values for the CONTAINED IN argument. Rows that became active exactly on the lower boundary or ceased being active exactly on the upper boundary are included. ...

As the characters/digits can be anywhere within the string, we require lookaheads. Lookaheads are of zero width meaning they do not consume any string. In simple words the position of checking resets to the original position after each condition of lookahead is met. Assumption :- Considering non-wo...
