  2. Calling convention - Wikipedia

    en.wikipedia.org/wiki/Calling_convention

    In the System/390 ABI [13] and the z/Architecture ABI, [14] used in Linux: Registers 0 and 1 are volatile; Registers 2 and 3 are used for parameter passing and return values; Registers 4 and 5 are also used for parameter passing; Register 6 is used for parameter passing, and must be saved and restored by the callee

  3. Evaluation strategy - Wikipedia

    en.wikipedia.org/wiki/Evaluation_strategy

    In a programming language, an evaluation strategy is a set of rules for evaluating expressions. [1] The term is often used to refer to the more specific notion of a parameter-passing strategy [2] that defines the kind of value that is passed to the function for each parameter (the binding strategy) [3] and whether to evaluate the parameters of a function call, and if so in what order (the ...

  4. Interface (Java) - Wikipedia

    en.wikipedia.org/wiki/Interface_(Java)

    Interfaces are commonly used in the Java language for callbacks, [4] as Java does not allow multiple inheritance of classes, nor does it allow the passing of methods (procedures) as arguments. Therefore, in order to pass a method as a parameter to a target method, current practice is to define and pass a reference to an interface as a means of ...

  5. Named parameter - Wikipedia

    en.wikipedia.org/wiki/Named_parameter

    A function call using named parameters differs from a regular function call in that the arguments are passed by associating each one with a parameter name, instead of providing an ordered list of arguments. For example, consider this Java or C# method call that doesn't use named parameters:

  6. Callback (computer programming) - Wikipedia

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

    Notably, the delivery need not be made by the clerk who took the order. A callback need not be called by the function that accepted the callback as a parameter. Also, the delivery need not be made directly to the customer. A callback need not be to the calling function. In fact, a function would generally not pass itself as a callback.

  7. Parameter (computer programming) - Wikipedia

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

    The specification for pass-by-reference or pass-by-value would be made in the function declaration and/or definition. Parameters appear in procedure definitions; arguments appear in procedure calls. In the function definition f(x) = x*x the variable x is a parameter; in the function call f(2) the value 2 is the argument of the function. Loosely ...

  8. Comparison of Java and C++ - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Java_and_C++

    For passing parameters to functions, C++ supports both pass-by-reference and pass-by-value. In Java, primitive parameters are always passed by value. Class types, interface types, and array types are collectively called reference types in Java and are also always passed by value. [11] [12] [13]

  9. 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.
