For instance, a function might be able to provide a promise that immediately resolves to some result value (such as C#'s Task.FromResult() [13]: 656 ), or it may simply return another method's promise that happens to be the exact promise needed (such as when deferring to an overload).
For example, a physics system may query for entities having mass, velocity and position components, and iterate over the results doing physics calculations on the set of components for each entity. The behavior of an entity can be changed at runtime by systems that add, remove or modify components.
In this example, a user identifier (userId) is the key for the associated user information object. The code first attempts to get this user information from the cache using the userId key. If that does not succeed, the code retrieves the information with a database query and then stores the returned user data in the cache.
Providing a static method that returns a reference to the instance; The instance is usually stored as a private static variable; the instance is created when the variable is initialized, at some point before when the static method is first called. This C++23 implementation is based on the pre-C++98 implementation in the book [citation needed].
Scaffolding is a technique supported by some model–view–controller frameworks, in which the programmer can specify how the application database may be used.The compiler or framework uses this specification, together with pre-defined code templates, to generate the final code that the application can use to create, read, update and delete database entries, effectively treating the templates ...
Users of Stack Overflow can earn reputation points and "badges"; for example, a person is awarded 10 reputation points for receiving an "up" vote on a question or an answer to a question, [12] and can receive badges for their valued contributions, [13] which represents a gamification of the traditional Q&A website. Users unlock new privileges ...
A document-oriented database is a specialized key-value store, which itself is another NoSQL database category. In a simple key-value store, the document content is opaque. A document-oriented database provides APIs or a query/update language that exposes the ability to query or update based on the internal structure in the document. This ...
