  2. Encapsulation (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Encapsulation_(computer...

    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.

  3. Information hiding - Wikipedia

    en.wikipedia.org/wiki/Information_hiding

    For example, a relational database is encapsulated in the sense that its only public interface is a query language (such as SQL), which hides all the internal machinery and data structures of the database management system. As such, encapsulation is a core principle of good software architecture, at every level of granularity.

    In some cases, true host-guest reversibility is observed, in other cases, the encapsulated guest cannot escape. [13] Molecular encapsulation of a nitrobenzene bound within a hemicarcerand. [14] An important implication of encapsulation (and host-guest chemistry in general) is that the guest behaves differently from the way it would when in ...

  5. Encapsulation (networking) - Wikipedia

    en.wikipedia.org/wiki/Encapsulation_(networking)

    For example, in the IP suite, the contents of a web page are encapsulated with an HTTP header, then by a TCP header, an IP header, and, finally, by a frame header and trailer. The frame is forwarded to the destination node as a stream of bits , where it is decapsulated into the respective PDUs and interpreted at each layer by the receiving node.

  6. Encapsulation - Wikipedia

    en.wikipedia.org/wiki/Encapsulation

    Encapsulation (networking), the process of adding control information as it passes through the layered model Encapsulation (computer programming) , the combination of program code and data, and/or restriction (hide) of access to data except through dedicated code

  7. Field encapsulation - Wikipedia

    en.wikipedia.org/wiki/Field_encapsulation

    In computer programming, field encapsulation involves providing methods that can be used to read from or write to the field rather than accessing the field directly. Sometimes these accessor methods are called getX and setX (where X is the field's name), which are also known as mutator methods.

  8. Data encapsulation - Wikipedia

    en.wikipedia.org/wiki/Data_encapsulation

    Data encapsulation, also known as data hiding, is the mechanism whereby the implementation details of a class are kept hidden from the user. The user can only perform a restricted set of operations on the hidden members of the class by executing special functions commonly called methods to prevent attributes of objects from being easily viewed and accessed.

  9. Mutator method - Wikipedia

    en.wikipedia.org/wiki/Mutator_method

    For example, if a date is represented by separate private year, month and day variables, then incoming dates can be split by the setDate mutator while for consistency the same private instance variables are accessed by setYear and setMonth. In all cases month values outside of 1 - 12 can be rejected by the same code.
