In software systems, encapsulation refers to the bundling of data with the mechanisms or methods that operate on the data. It may also refer to the limiting of direct access to some of that data, such as an object's components. [1] Essentially, encapsulation prevents external code from being concerned with the internal workings of an object.
Encapsulation is a means of information hiding. [2] Layered designs in information systems are another embodiment of separation of concerns (e.g., presentation layer, business logic layer, data access layer, persistence layer). [3] Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or ...
Encapsulation (computer programming), the combination of program code and data, and/or restriction (hide) of access to data except through dedicated code Topics referred to by the same term This disambiguation page lists articles associated with the title Encapsulation .
Some naming conventions limit whether letters may appear in uppercase or lowercase. Other conventions do not restrict letter case, but attach a well-defined interpretation based on letter case. Some naming conventions specify whether alphabetic, numeric, or alphanumeric characters may be used, and if so, in what sequence.
A software module hides information by encapsulating the information into a module or other construct which presents an interface. [ 1 ] A common use of information hiding is to hide the physical storage layout for data so that if it is changed, the change is restricted to a small subset of the total program.
[1] [2] Constructor theory expresses physical laws exclusively in terms of which physical transformations, or tasks, are possible versus which are impossible, and why. By allowing such counterfactual statements into fundamental physics, it allows new physical laws to be expressed, such as the constructor theory of information.
The facade pattern (also spelled façade) is a software design pattern commonly used in object-oriented programming.Analogous to a façade in architecture, it is an object that serves as a front-facing interface masking more complex underlying or structural code.
The nested function technology allows a programmer to write source code that includes beneficial attributes such as information hiding, encapsulation and decomposition.The programmer can divide a task into subtasks which are only meaningful within the context of the task such that the subtask functions are hidden from callers that are not designed to use them.
