In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software, [1] [2]: 7 following the reusability principles.
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
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall , prototyping , iterative and incremental development , spiral development , agile software development , rapid application development , and extreme programming .
In a highly cohesive system, code readability and reusability is increased, while complexity is kept manageable. Cohesion. Cohesion is increased if: The functionalities embedded in a class, accessed through its methods, have much in common. Methods carry out a small number of related activities, by avoiding coarsely grained or unrelated sets of ...
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]
