While code is the most common resource selected for reuse, other assets generated during the development cycle may offer opportunities for reuse: software components, test suites, designs, documentation, and so on. [7] The software library is a good example of code reuse. Programmers may decide to create internal abstractions so that certain ...
In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation.
When making calls to a supplier, a software module should not violate the supplier's preconditions. Design by contract can also facilitate code reuse, since the contract for each piece of code is fully documented. The contracts for a module can be regarded as a form of software documentation for the behavior of that module.
Inheritance allows programmers to create classes that are built upon existing classes, [1] to specify a new implementation while maintaining the same behaviors (realizing an interface), to reuse code and to independently extend original software via public classes and interfaces.
In software engineering, many reuse metrics and models are metrics used to measure code reuse and reusability. A metric is a quantitative indicator of an attribute of a thing. A model specifies relationships among metrics. Reuse models and metrics can be categorized into six types: reuse cost-benefits models; maturity assessment
This is a list of approaches, styles, methodologies, and philosophies in software development and engineering. It also contains programming paradigms , software development methodologies , software development processes , and single practices, principles, and laws.
A study done by NASA showed that the putting the code into well-factored classes can double the code reusability compared to the code developed using functional design. [10] [11] One experiment showed that designs which access arrays sequentially, rather than randomly, result in fewer variables and fewer variable references. [12]
For example, in the C# code below, the variables and methods of the Employee base class are inherited by the HourlyEmployee and SalariedEmployee derived subclasses. Only the Pay() method needs to be implemented (specialized) by each derived subclass. The other methods are implemented by the base class itself, and are shared by all of its ...
