  • MAC OS the MAC OS
  • UNIX operating system a preferred embodiment is written using JAVA, C, and the C++ language and utilizes object oriented programming methodology.
  • Object oriented programming (OOP) has become increasingly used to develop complex applications. As OOP moves toward the mainstream of software design and development, various software solutions require adaptation to make use of the benefits of OOP. A need exists for these principles of OOP to be applied to a messaging interface of an electronic messaging system such that a set of OOP classes and objects for the messaging interface can be provided.
  • OOP is a process of developing computer software using objects, including the steps of analyzing the problem, designing the system, and constructing the program.
  • An object is a software package that contains both data and a collection of related structures and procedures.
  • OOP Since it contains both data and a collection of structures and procedures, it can be visualized as a self-sufficient component that does not require other additional structures, procedures or data to perform its specific task. OOP, therefore, views a computer program as a collection of largely autonomous components, called objects, each of which is responsible for a specific task. This concept of packaging data, structures, and procedures together in one component or module is called encapsulation.
  • OOP components are reusable software modules which present an interface that conforms to an object model and which are accessed at run-time through a component integration architecture.
  • a component integration architecture is a set of architecture mechanisms which allow software modules in different process spaces to utilize each others capabilities or functions. This is generally done by assuming a common component object model on which to build the architecture. It is worthwhile to differentiate between an object and a class of objects at this point.
  • An object is a single instance of the class of objects, which is often just called a class.
  • a class of objects can be viewed as a blueprint, from which many objects can be formed.
  • OOP allows the programmer to create an object that is a part of another object.
  • the object representing a piston engine is said to have a composition-relationship with the object representing a piston.
  • a piston engine comprises a piston, valves and many other components; the fact that a piston is an element of a piston engine can be logically and semantically represented in OOP by two objects.
  • OOP also allows creation of an object that "depends from" another object. If there are two objects, one representing a piston engine and the other representing a piston engine wherein the piston is made of ceramic, then the relationship between the two objects is not that of composition. A ceramic piston engine does not make up a piston engine.
  • the object representing the ceramic piston engine is called a derived object, and it inherits all of the aspects of the object representing the piston engine and adds further limitation or detail to it.
  • the object representing the ceramic piston engine "depends from” the object representing the piston engine. The relationship between these objects is called inheritance.
  • the object or class representing the ceramic piston engine inherits all of the aspects of the objects representing the piston engine, it inherits the thermal characteristics of a standard piston defined in the piston engine class.
  • the ceramic piston engine object overrides these ceramic specific thermal characteristics, which are typically different from those associated with a metal piston. It skips over the original and uses new functions related to ceramic pistons.
  • Different kinds of piston engines have different characteristics, but may have the same underlying functions associated with it (e.g., how many pistons in the engine, ignition sequences, lubrication, etc.).
  • a programmer would call the same functions with the same names, but each type of piston engine may have different/overriding implementations of functions behind the same name. This ability to hide different implementations of a function behind the same name is called polymorphism and it greatly simplifies communication among objects.
  • composition-relationship With the concepts of composition-relationship, encapsulation, inheritance and polymorphism, an object can represent just about anything in the real world. In fact, one's logical perception of the reality is the only limit on determining the kinds of things that can become objects in object- oriented software. Some typical categories are as follows:
  • Objects can represent physical objects, such as automobiles in a traffic-flow simulation, electrical components in a circuit-design program, countries in an economics model, or aircraft in an air-traffic-control system.
  • Objects can represent elements of the computer-user environment such as windows, menus or graphics objects.
  • An object can represent an inventory, such as a personnel file or a table of the latitudes and longitudes of cities.
  • An object can represent user-defined data types such as time, angles, and complex numbers, or points on the plane.
  • OOP allows the software developer to design and implement a computer program that is a model of some aspects of reality, whether that reality is a physical entity, a process, a system, or a composition of matter. Since the object can represent anything, the software developer can create an object which can be used as a component in a larger software project in the future.
  • OOP enables software developers to build objects out of other, previously built objects.
  • C++ is an OOP language that offers a fast, machine-executable code.
  • C++ is suitable for both commercial-application and systems-programming projects.
  • C++ appears to be the most popular choice among many OOP programmers, but there is a host of other OOP languages, such as Smalltalk, Common Lisp Object System (CLOS), and Eiffel. Additionally, OOP capabilities are being added to more traditional popular computer programming languages such as Pascal.
  • object classes can be summarized, as follows:
  • Encapsulation enforces data abstraction through the organization of data into small, independent objects that can communicate with each other. Encapsulation protects the data in an object from accidental damage, but allows other objects to interact with that data by calling the object's member functions and structures.
  • Class hierarchies and containment hierarchies provide a flexible mechanism for modeling real-world objects and the relationships among them.
  • Class libraries are very flexible. As programs grow more complex, more programmers are forced to adopt basic solutions to basic problems over and over again.
  • a relatively new extension of the class library concept is to have a framework of class libraries. This framework is more complex and consists of significant collections of collaborating classes that capture both the small scale patterns and major mechanisms that implement the common requirements and design in a specific application domain. They were first developed to free application programmers from the chores involved in displaying menus, windows, dialog boxes, and other standard user interface elements for personal computers.
  • Frameworks also represent a change in the way programmers think about the interaction between the code they write and code written by others.
  • the programmer called libraries provided by the operating system to perform certain tasks, but basically the program executed down the page from start to finish, and the programmer was solely responsible for the flow of control. This was appropriate for printing out paychecks, calculating a mathematical table, or solving other problems with a program that executed in just one way.
  • a programmer writing a framework program not only relinquishes control to the user (as is also true for event loop programs), but also relinquishes the detailed flow of control within the program to the framework. This approach allows the creation of more complex systems that work together in interesting ways, as opposed to isolated programs, having custom code, being created over and over again for similar problems.
  • a framework basically is a collection of cooperating classes that make up a reusable design solution for a given problem domain. It typically includes objects that provide default behavior (e.g., for menus and windows), and programmers use it by inheriting some of that default behavior and overriding other behavior so that the framework calls application code at the appropriate times.
  • default behavior e.g., for menus and windows
  • Behavior versus protocol Class libraries are essentially collections of behaviors that you can call when you want those individual behaviors in your program.
  • a framework provides not only behavior but also the protocol or set of rules that govern the ways in which behaviors can be combined, including rules for what a programmer is supposed to provide versus what the framework provides.
