The implementation module, starting with the keyword MODULE, provides the code, and any further constants, types, or variables needed to implement the interface. By default, an implementation module will implement the interface of the same name, but a module may explicitly EXPORT to a module not of the same name. For example, the main program ...
.NET allows six varieties of generic type constraints using the where keyword including restricting generic types to be value types, to be classes, to have constructors, and to implement interfaces. [30] Below is an example with an interface constraint:
Concepts are an example of structural typing. As generics in Java and C# have some similarities to C++'s templates, the role of concepts there is played by interfaces. However, there is one important difference between concepts and interfaces: when a template parameter is required to implement a particular interface, the matching type can only ...
A browser window allows the user to view and navigate through a collection of items, such as files or web pages. Web browsers are an example of these types of windows. Text terminal windows present a character-based, command-driven text user interfaces within the overall graphical interface. MS-DOS and Unix consoles are examples of these types ...

For example, to check whether an item is included in a list, we need to compare the items for equality. In Standard ML , type parameters of the form ’’a are restricted so that the equality operation is available, thus the function would have the type ’’a × ’’a list → bool and ’’a can only be a type with defined equality.
An IUnknown (or IUnknown-derived) interface consists of a pointer to a virtual method table that contains a list of pointers to the functions that implement the functions declared in the interface, in the order that they are declared in the interface. The in-process invocation call overhead is therefore identical to virtual method calls in C++.
The PHP Standard Recommendation (PSR) is a PHP specification published by the PHP Framework Interop Group. Similar to Java Specification Request for Java, it serves the standardization of programming concepts in PHP. The aim is to enable interoperability of components and to provide a common technical basis for implementation of proven concepts ...
