This can include real-time monitoring of the API with alerts being raised directly or via a higher-level network management system, for instance, if the load on an API has become too great, as well as functionality to analyze historical data, such as transaction logs, to detect usage trends. Functionality can also be provided to create ...
Implementations may also be provided for non real-time operating systems, allowing the abstracted software to be developed and tested in a developer friendly desktop environment. In addition to the OS APIs, the OS abstraction layer project may also provide a hardware abstraction layer , designed to provide a portable interface to hardware ...
API description languages are sometimes called interface description languages (IDLs). The structured description might be used to generate documentation for human programmers ; such documentation may be easier to read than free-form documentation, since all documentation generated by the same tool follows the same formatting conventions.
A compile-time binding between an abstraction and its implementation should be avoided so that an implementation can be selected at run-time. When using subclassing, different subclasses implement an abstract class in different ways. But an implementation is bound to the abstraction at compile-time and cannot be changed at run-time.
This PHP example shows interface implementations instead of subclassing (however, the same can be achieved through subclassing). The factory method can also be defined as public and called directly by the client code (in contrast to the previous Java example).
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. [1] A document or standard that describes how to build such a connection or interface is called an API specification.
The Doctrine Project (or Doctrine) is a set of PHP libraries primarily focused on providing persistence services and related functionality. Its most commonly known [ according to whom? ] projects are the object–relational mapper (ORM) and the database abstraction layer it is built on top of.
Soft real-time systems are typically used to solve issues of concurrent access and the need to keep a number of connected systems up-to-date through changing situations. Some examples of soft real-time systems: Software that maintains and updates the flight plans for commercial airliners. The flight plans must be kept reasonably current, but ...
