Programming Languages Object-Oriented

The smaller-grained components in Section 10.6.1 and Section 10.6.2 are also very similar to objects. In fact, they would be easiest to implement as objects in an object-oriented programming language. This shows that the differences between component-based... 

All object-oriented programming languages provide a feature called access modifier that facilitates separations between the interfaces and the implementations of an object. The way to achieve this result is to define member variables of the object as private or protected and define methods that provide services to the object s client as public. Only the public elements of an object can be accessed by its clients, and these are all that its clients care to know. In Java and C, we can go even further by creating interfaces that have only method signatures. The implementations of these methods are provided by the classes that implement these interfaces. Although there is no interface in C + +, you can, however, create an abstract class by declaring one or more of the class s methods as pure virtual. Abstract class is also supported by Java and C. Interfaces and abstract classes are useful software constructs for defining abstractions in a software system. 

Parts of this strategy have already been mapped out through the introduction of software products such as JAVA, an object-oriented programming language (6) suitable for immediate integration with Internet tools for distributed application across wide-area networks. In this approach, solutions to specialized problems are made available to users in the form of applets, or program modules, which can easily be... 

VBA is an object-oriented programming language. Objects in Microsoft Excel are the familiar components of Excel, such as a worksheet, a chart, a toolbar or a range. Objects have properties and methods associated with them. Objects are the nouns of the language, properties are the adjectives, and methods are the verbs. 

The strength of a ternary acid is estimated from the difference between the number of oxygen atoms and hydrogen atoms. Facts are asserted by a simple assignment statement, similar to object-oriented programming languages ... 

Randall B. Smith received his Ph.D. in theoretical physics at the University of California at San Diego and taught for two years before becoming involved in computer science with Atari Computer Corporate Research Group. He joined the Xerox Palo Alto Research Center a year later, where he completed the work described in his chapter. He is now at Sun Labs, Palo Alto. His interests include object-oriented programming languages and environments, educational uses of computers, and computer support for collaborative work. 

Object-oriented programming languages typically rely on dynamic memory allocation to allocate all objects of non-primitive types. Therefore, if safety-critical systems are constructed using object technology, it is necessary to establish policies for the safe use of dynamic memory allocation. We suggest here two such policies. 

Suitability of Mainstream Object-Oriented Programming Languages... 

Safety-critical developers rightly complain about the unsuitability of mainstream object-oriented programming languages for critical systems. The most widely used object-oriented programming language is C++, which inherits nearly all the problems of C and adds a few new ones such as ambiguous method calls. 

Object-oriented programming languages tend to rely on dynamic memory management. The supplement introduces an additional objective and related activities to verify dynamic memory management. The activities are aimed to ensure that none of the following vulnerabilities exist ... 

A rather young object-oriented programming language with roots in C-f-h, Modula II, and Smalltalk. Java provides... 

In most current object-oriented programming languages, the possibility exists that a class of objects can inherit attributes from more than one superclass (multiple inheritance). 

Constraints on the implementation technologies available. It should be noted that a fuzzy Object Oriented programming language has been proposed by Yasunobu et al [Yas91, Yam91, Ino91]. 

PCs), the development of Windows-based systems software, and the development of object-oriented programming languages. This combination of inexpensive hardware and system tools has led to the proliferation of exceptionally user-friendly and robust software tools for steady-state process simulation and design. Dynamic simulation naturally developed along with the steady-state simulators [24]. Figure 1.1 presents a sunamary of the growth of dynamic process simulation. 

A prototype system framework of PEEE has been developed using Java and Visual Basic as object-oriented programming languages, while SQE server and MS-Access are used as RDBMS for data repository for the plant model elements. Such prototype solution will enable all plant users to utilize a standard user interface to manipulate plant lifecycle data/information/knowledge. The prototype system can be used as the framework to develop CAPE-SAFE as well as other components within PEEE.
