Study Notes
Abstraction
- Abstraction is a view or representation of an entity that includes only the most significant attributes.
- There are two fundamental kinds of abstraction: process abstraction and data abstraction.
- Process abstraction: specifies a process without providing the details of how it performs its task, similar to subprograms.
Data Abstraction
- An abstract data type is a data structure, in the form of a record, that includes subprograms that manipulate its data.
- An object is an instance of an abstract data type.
- Data abstraction is a fundamental component of object-oriented programming.
Characteristics of User-Defined Abstract Data Types
- A type definition that allows program units to declare variables of the type but hides the representation of objects of the type.
- A set of operations for manipulating objects of the type.
Benefits of Data Abstraction
- Reliability
- Reduction of code range and number of variables
- Less likelihood of name conflicts
- Change of data structure without affecting the client side
Getters and Setters
- Accessors allow clients indirect access to hidden data.
- Benefits of accessors include read-only access, constraints, and ability to change implementation without affecting clients.
Language Examples - C++
- Encapsulation: includes data members and member functions in a C++ class.
- Information Hiding: uses private, public, and protected access specifiers.
- Constructors and Destructors:
- Constructors have the same name as the class and are used to initialize objects.
- Constructors can be overloaded with unique parameter profiles.
- Destructors are used for debugging and deallocation, and have a name preceded by a tilde (~).
