Object Structuring Techniques

چکیده
The aim of this tutorial is to present practical techniques for structuring objects, with a particular focus on implementation strategies for making object structure explicit. Programming language support for encapsulation is primarily provided at the class or module level. Design methods merrily talk of object composition and aggregation, but there is little effective support provided in programming languages for direct representation of these abstractions in code. Typically composite structures are The tutorial will present the notion of object ownership, its underlying theory based on the graph theoretical notion of domination, and programming idioms for representing and maintaining ownership.

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...

Advanced future applications require to exploit new types of objects such as continuous media objects and distributed objects. Such new requirements stress operating systems to support variable levels of responsiveness and reliability. One computational model and resource management policy cannot cover the various requirements from all users so a exible structure is important when building futu...
متن کاملCan Scaffolding Mechanisms of Structuring and Problematizing Facilitate the Transfer of Genre-based Knowledge to Another Discourse Mode?
A pivotal issue in research on writing concerns whether the knowledge of how genres are constructed and learned in one discipline/genre can be transferred to other contexts, genres, and disciplines. Yet, studies conducted so far have not presented a unified and complete view of how various writing instructional techniques can result in transferability. This study examined the effect of structur...
متن کاملSome Elements of Z Specification Style: Structuring Techniques
This article investigates the issue of structuring Z specifications. It uses examples from a large specification (the production cell) to examine both conventions for using Z and notational extensions, including Object-Z. Because of the importance of good structure within a specification, specifiers need to be aware of a range of structuring techniques and understand where each is applicable.
