To treat a collection of structured information as a whole, without affecting or taking notice of its internal structure In communications, a message or packet that is constructed according to a protocol, such as a TCP/IP packet, may be taken with its formatting data as an undifferentiated stream of bits that is then broken up and packaged according to a lower-level protocol (for example, as asynchronous transfer mode (ATM) packets) to be sent over a particular network At the destination, the lower-level packets are assembled, recreating the message as it was formatted for the encapsulated protocol
To put an existing file system into a one-way concatenation A one-way concatenation consists of a single slice
To divide a large complex program into components (like methods) and isolate the components from each other (for example, by using local variables)
To seal a pesticide or its container in a container which will not be degraded by the pesticide, and then again within a container which will resist physical damage
Sealing up or covering an element or circuit for mechanical and environmental protection
To treat a collection of structured information as a whole without affecting or taking notice of its internal structure In communications, a message or packet constructed according to a protocol such as a TCP/IP packet, may be taken with its formatting data as an undifferentiated stream of bits that is then broken up and packaged according to a lower-level protocol (for example, as ATM packets) to be sent over a particular network; at the destination, the lower-level packets are assembled, re-creating the message as formatted for the encapsulated protocol
A basic protocol layering technique The information from a higher level protocol (which may include both data & headers) is carried as the data portion of lower-level protocol, which adds its own header information For example, IP datagrams are encapsulated in Data Link packets
To encapsulate particular facts or ideas means to represent all their most important aspects in a very small space or in a single object or event. A Wall Street Journal editorial encapsulated the views of many conservatives His ideas were encapsulated in a book called `Democratic Ideals and Reality'. + encapsulation encapsulations en·cap·su·la·tion a witty encapsulation of modern America
A rigid, transparent, protective casing in which a coin is placed to protect it from corrosion and damage For special collector issues, this case is usually made of two halves of an inert moulded plastic material to the exact dimensions of the coin to be protected The two halves are either screwed or pressed together to 'encapsulate' the coin
Encapsulation describes the ability of an object to hide its data and methods from the rest of the world - one of the fundamental principles of OOP (Object Oriented Programming)
The localization of knowledge within a module Because objects encapsulate data and implementation, the user of an object can view the object as a black box that provides services Instance variables and methods can be added, deleted, or changed, but as long as the services provided by the object remain the same, code that uses the object can continue to use it without being rewritten
The idea that we can create a set of procedures (methods and properties) that form an interface Other code can be written to use these methods without knowledge of the code written within them This code is called an implementation The implementation is encapsulated within the interface
You might know this under the name of "information hiding" The idea is that data belonging to an object is under the control of the methods (also known as functions) of that object, and may not be accessed in any way other than by those methods The implementation details of the methods are not generally known What is generally known is what each method does, and the prototype for each method So the developer using a method knows what parameters to pass to it, and what sort of result will be returned, and any side-effects that it may have The developer does not know, and does not need to know, how the method achieves its purpose The data belonging to each object is only accessible by using these methods - hence it is "encapsulated"
A form of protective enclosure for paper and other flat objects It involves placing the item between two sheets (or one folded sheet) of clear plastic film (usually polyester), that are subsequently sealed with adhesive tape or by heat welding or sewing around the edges The object is thus physically supported and protected from the atmosphere, although it may continue to deteriorate within the package A sheet of buffered paper or board is sometimes included The object can simply be removed by cutting one or more edges of the plastic film
In open systems, the technique used by layered protocols in which a lower layer protocol accepts a message from a higher layer protocol and places it in the data portion of a frame in the lower layer
The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above As an example, in Internet terminology, a packet would contain a header from the physical layer, followed by a header from the network layer (IP), followed by a header from the transport layer (TCP), followed by the application protocol data
A process by which an interface device places an end device's protocol-specific frames inside a frame relay frame The network accepts only frames formatted specifically for frame relay; hence, interface devices acting as interfaces to an frame relay network must perform encapsulation See also Interface device or Frame-Relay-Capable Interface Device
The result of hiding a representation and implementation in an object The representation is not visible and cannot be accessed directly from outside the object Operations are the only way to access and modify an object's representation [Gamma+ 95]
[M206] The internal structure of an object is available to the object itself, but it is not available to any other object For example, an object cannot directly reference the instance variables of another object Objects are said to be encapsulated, responding only to messages in their protocol [P&S] Encapsulation is when a client of a module isn't able to know more than is in the interface
Or micro-encapsulation: the encapsulation of a pesticide in a non-volatile envelope of gelatine, polyvinyl or other material, usually of minute size, for controlled release of the chemical to extend the period of diffusion
This is also referred to as Time Engineering In this remediation technique, all dates are set back by 28 years, or a multiple of 28, because every 28 years the calendar repeats itself and the days of the week and the calendar dates would be in correct synchronization
In object-oriented programming, encapsulation is the inclusion within a separate file of all the resources needed for the object to function as a class
This is the scheme used for defining objects in object-oriented approach Encapsulation hides detailed internal specification of an object, and publishes only its external interfaces Thus, users of an object only need to adhere to these interfaces By encapsulation, the internal data and methods of an object can be changed without changing the way of how to use the object
Information hiding within an abstraction that is supported by features of a programming language, so that the information hiding is guaranteed to be complete
The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above For example, a packet contains a header from the physical layer, followed by a header from the network layer (IP), followed by a header from the transport layer (TCP), followed by the application protocol data
Taking data formatted for one protocol and enclosing it within another protocol in order to transmit the data successfully across a type of network the original protocol was not designed for
Encapsulation is a C++Builder - OOPs term The act of putting data in the private section of a class definition thus protecting the data from access outside of the object, even in a read-only way By protecting the data, the programmer can control the data This control allows the programmer to know that the only way the data is changed is by using the objects method Although this concept may seem more difficult to employ, objects become easier to use down the line since the purpose and use of the data is designed by the methods used for access Think of encapsulation as "data protection " See "Implementation of TObject" in the Articles Section for more information
{i} state of being enclosed within a capsule; act of placing or enclosing in a capsule; insertion of all methods and data needed for independent operation into one program; (Telecommunications) inclusion of one data structure within another
a means by which object A hide the details of its implementation from object B Object B only needs to know what object A can do, not how it does it (Using Objects - Slide 12)
(n ) The localization of knowledge within a module Because objects encapsulate data and implementation, the user of an object can view the object as a black box that provides services Instance variables and methods can be added, deleted, or changed, but if the services provided by the object remain the same, code that uses the object can continue to use it without being rewritten See also instance method, instance variable
A soils contamination remediation process that encapsulates the soils to prevent leaching and surface seepage of contamination into either the groundwater or storm drainage system A monitoring facility is usually required
The act of placing code or data in a location, such as a module or control, that's isolated from the rest of an application Encapsulation hides both the implementation details and the internal complexity of an object but still enables the application to use functions contained within it
The process by which each protocol adds header information to a datagram The header information included information regarding the source, destination and route of the message
