In maintenance, assuring code quality and operation, software metrics is widely used by the various software organizations. Software metrics quantify different types of software complexity like size metrics, control flow metrics and data flow metrics. These software complexities must be continuously calculated, followed and controlled. One of the main objectives of software metrics is that measures static and dynamic metrics analysis. It is always considered that high degree of complexity in a fragment is bad in comparison to a low degree of complexity in a fragment. Software metrics can be used in different phases of the software lifecycle. In this paper we will discuss the different metrics and comparison between both static and dynamic metrics. We try to evaluate and analyze different aspects of software static and dynamic metrics in regression testing which offers of estimating the effort needed for testing.

IEC 62541-10:2015 is part of the overall OPC Unified Architecture (OPC UA) standard series and defines the information model associated with Programs. This includes the description of the NodeClasses, standard Properties, Methods and Events and associated behaviour and information for Programs. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. It includes the following technical changes: - Based on NIST review, security considerations have been included as 4.2.2;- Fixed the definition of the Program Diagnostic Type into a data type (5.2.8) and added missing data type for the Program Diagnostic Variable in the ProgramType in Table 5;- Corrected the BrowseName of the audit events for Program Transitions in Table 7.

P³: a code and design conventions preprocessor for Java

引用

Software: Practice and Experience 2002年第1期33卷

One of the techniques employed by programmers during the development process is the use of code and design conventions. These are rules-of-thumb or best practices that improve the maintainability of software applications. In general, these conventions are maintained manually by the programmer since automated support is usually restricted to the automatic generation of code. However, the late discovery of convention errors can result in significant costs due to the effort required to correct them. In order to facilitate the early detection of these errors, the Practical Preprocessor for programming Conventions system, P³ (pronounced P3),is proposed. This tool acts as a preprocessor to the Java compiler by providing facilities for the maintenance of specific object-oriented code conventions and design principles during the creation of Java programs. This paper presents the design and implementation of the P³ system and also the practical experience of using this facility in a University programming environment.

Message Filters for object-oriented Systems

Software: Practice and Experience 1999年第6期27卷

In the conventional object model, encapsulated objects interact by messages that result in method invocations on the destination object. A message is delivered directly at the destination object. As a result of the direct deliveries, the message control code performing intermediate message manipulations cannot be abstracted out separately from the message processing code in the destination object without sacrificing the transparency of the intermediate message control. We propose the filtered delivery model of message passing for object-oriented languages to provide the separation of message control from message processing in a transparent manner. An interclass relationship, called a filter relationship , is introduced. As a consequence, a filter object can intercept and manipulate messages sent to another object called its client via filter member functions. A filter member function in a filter object can intercept a particular member function invocation on its client object. The filtered delivery model supports both upward and downward filtering mechanisms, facilitating interception of an upward message and its return message value. Filter objects can be plugged or unplugged at runtime. Binding of filter member functions to corresponding member functions in the client is selective and dynamic. The filtered delivery model is developed for the C++ object-oriented language; its applications are described and implementation is discussed. © 1997 John Wiley & Sons, Ltd.

An implementation of disk objects in the logical machine monitor

User or program mobility in distributed computing systems is becoming increasingly significant, since users may sometimes change their working locations. This paper proposes a Logical Machine (LM) system that can effectively support software environment migration and resource mapping. The LM partitions the conventional operating systems into two parts: the Logical Machine Operating System (LMOS) and the Logical Machine Monitor (LMM). They are responsible for user service and system resource management, respectively. The LMM provides a machine independent appearance, called the Logical Machine Interface (LMI), for the upper operating system layers to provide the resources they need. In our experimental system, the LMM contains some disk objects that can be bound dynamically. By varying the binds, the users get different disk characteristics. A mobile disk object with the mechanism of block migration on demand is implemented. It can be incorporated with a logical machine migration facility to achieve job migration, i.e., the user can migrate the operating system and disk blocks to the place he or she desires. The mobile disk also simplifies the mechanism of parallel processing when each server reads and processes its data portion locally. With this approach, the system resources can be mapped more flexibly, while transparency to the operating system is retained. © 1997 John Wiley & Sons, Ltd.

A C++ Simulator Generator from Graphical Specifications

Software: Practice and Experience 1999年第4期27卷

Many languages for computer systems simulation (like GPSS and CSim) use a stochastic model of systems with the provision of adding procedural code for those aspects of the system that cannot be captured easily by a stochastic model. However, they do not support the hierachical simulation of complex systems well. Complex computer systems may have to be simulated at various levels of abstraction in the interests of tractability: the flexibility of being able to freely move between the different levels of abstraction is very desirable. For example, in the area of computer architecture, one might have analytical models, detailed simulation models and trace-driven models. In addition, these languages do not have user-friendly interfaces for specification of the simulated system. In this paper, we discuss the design and implementation of a simulation package for hierachical simulation of non-real-time computer systems: a Simulator Generator from a Graphical System Specification (SIGGSYS}). A new language for system specification has been designed. In addition, the package has the following components: • A graphical user interface to aid specification of the system to be simulated. • A rear end that generates C++ code that implements a simulator for the specified system. • A complete object library along with the header files that implement a functionally complete set of C++ base classes which can be built upon. C++ has been chosen as the intermediate language so that the modeller can use its support for object oriented programming. © 1997 John Wiley & Sons, Ltd.
