  2. Futures and promises - Wikipedia

    en.wikipedia.org/wiki/Futures_and_promises

    In C++11 a std::future provides a read-only view. The value is set directly by using a std::promise, or set to the result of a function call using std::packaged_task or std::async. In the Dojo Toolkit's Deferred API as of version 1.5, a consumer-only promise object represents a read-only view. [7]

  3. Active object - Wikipedia

    en.wikipedia.org/wiki/Active_object

    The goal is to introduce concurrency, by using asynchronous method invocation and a scheduler for handling requests. [2] The pattern consists of six elements: [3] A proxy, which provides an interface towards clients with publicly accessible methods. An interface which defines the method request on an active object. A list of pending requests ...

  4. Message passing - Wikipedia

    en.wikipedia.org/wiki/Message_passing

    In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer.The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code.

  5. Callback (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Callback_(computer...

    In the following C# code, method Helper.Method uses parameter callback as a blocking callback. Helper.Method is called with Log which acts as a callback function. When run, the following is written to the console: "Callback was: Hello world".

  6. Asynchronous method invocation - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_method_invocation

    Alternatives are synchronous method invocation and future objects. [4] An example for an application that may make use of AMI is a web browser that needs to display a web page even before all images are loaded. Since method is a special case of procedure, asynchronous method invocation is a special case of asynchronous procedure call.

  7. Async/await - Wikipedia

    en.wikipedia.org/wiki/Async/await

    Swift added support for async/await with version 5.5 in 2021, adding 2 new keywords async and await. This was released alongside a concrete implementation of the Actor model with the actor keyword [ 12 ] which uses async/await to mediate access to each actor from outside.

  8. Calling convention - Wikipedia

    en.wikipedia.org/wiki/Calling_convention

    Floating-point registers 0 and 2 are used for parameter passing and return values; Floating-point registers 4 and 6 are for use by the callee, and must be saved and restored by them; In z/Architecture, floating-point registers 1, 3, 5, and 7 through 15 are for use by the callee; Access register 0 is reserved for system use

  9. Multiple dispatch - Wikipedia

    en.wikipedia.org/wiki/Multiple_dispatch

    The data from these papers is summarized in the following table, where the dispatch ratio DR is the average number of methods per generic function; the choice ratio CR is the mean of the square of the number of methods (to better measure the frequency of functions with a large number of methods); [2] [3] and the degree of specialization DoS is ...
