Classes and Inheritance I have already covered inheritance in a limited way in the section “Object Expressions.” Inheri- tance allows you to extend a class that is already defined and to tweak its behavior to add new or replace original functionality. Like most modern object-<[r]
Time Geography provides a conceptual framework for capturing the semantics of space and time. This book introduces the reader to the framework abstractions developed in Time Geography. They are of primordial importance for handling spatio- temporal data in GIS. They play an important role as a model[r]
3.2. Retrieving design patterns from Ontology Artifacts of the analysis phase in the object oriented development process include simple class diagrams and simply interactive diagrams. These diagrams are results of modeling application requirements. We call th[r]
This chapter presents a set of criteria, activities, and techniques used to design classes and methods. Together they are used to ensure the object-oriented design communicates how the system needs to be coded.
The price of the itemId 1 = 15.0 What is a dynamic proxỷ Dynamic proxies were introduced in J2SE 1.3, and provide an alternate dynamic mechanism for implementing many common design patterns like Façade, Bridge, Decorator, Proxy (remote proxy and virtual proxy), and Adapter. While all of[r]
2. Core language. When I was editor of the C++ Report , I used to say that half the job of editing the magazine was in deciding what not to put in. The same is true for this text. The text is organized around a series of a programming problems. Language features are introduced to[r]
< Access time to versions will decrease with their age. Based on this evaluation by Dadam, Lum and Werner (1984), the backward-oriented accumulative strategy has been adopted in the STDM. The main advantage seen in this strategy is that for each version in the STDM, an accumulative delta[r]
OBJECT-ORIENTED DESIGN FOR TEMPORAL GIS 98 They are regarded as three-dimensional (2D space+time) or higher-dimensional entities whose structure and behaviour is captured by modelling them as abstract data types (ADTs). These abstract types can be implemented as attribute da[r]
There are two ways to produce a visual representation of the different states of a public boundary. An external class can be defined in order to query each object in terms of each kind of graphical display to be employed. Alternatively, each object can encapsulate the knowledge of how[r]
Another complementary criterion is the need to represent the dynamics of change within the object-oriented methodology. There is a need for handling rules (topological rules), constraints (capacity, coupling and authority constraints), and methods (trigger methods—update, delete, creat[r]
