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 ...
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 ...
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; amount of ...
For example, a parent class, A, can have two subclasses B and C. Both B and C's parent class is A, but B and C are two separate subclasses. Hybrid inheritance Hybrid inheritance is when a mix of two or more of the above types of inheritance occurs. An example of this is when a class A has a subclass B which has two subclasses, C and D.
The ability to reuse can be viewed as the ability to build larger things from smaller parts, and to identify commonality among the parts. Reusability is often a required characteristic of platform software. Reusability brings several aspects to software development that do not need to be considered when reusability is not required.
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.
Object-oriented modeling (OOM) is an approach to modeling an application that is used at the beginning of the software life cycle when using an object-oriented approach to software development. The software life cycle is typically divided up into stages going from abstract descriptions of the problem to designs then to code and testing and ...
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.
