Component Diagrams in UML
9. UML Component Diagrams Page 1 of 4 Component Diagrams in UML The previous articles covered two of the three primary areas in which the UML diagrams are categorized (see Article 1)—Static and Dynamic. The remaining two UML diagrams that fall under the category of Implementation are the Component and Deployment diagrams. In this article, we will discuss the Component diagram. Basics The different high-level reusable parts of a system are represented in a Component diagram. A component is one such constituent part of a system. In addition to representing the high-level parts, the Component diagram also captures the inter- relationships between these parts. So, how are component diagrams different from the previous UML diagrams that we have seen? The primary difference is that Component diagrams represent the implementation perspective of a system. Hence, components in a Component diagram reflect grouping of the different design elements of a system, for example, classes of the system. Let us briefly understand what criteria to apply to model a component. First and foremost, a component should be substitutable as is. Secondly, a component must provide an interface to enable other components to interact and use the services provided by the component. So, why would not a design element like an interface suffice? An interface provides only the service but not the implementation. Implementation is normally provided by a class that implements the interface. In complex systems, the physical implementation of a defined service is provided by a group of classes rather than a single class. A component is an easy way to represent the grouping together of such implementation classes. -

ABSTRACT realistic experiences necessary to a VR scene, but not asset creation In this paper we present AffordIt!, a tool for adding affordances (a situation described in Hughes et al. [17]) which are needed to to the component parts of a virtual object. Following 3D scene build a virtual scene. To alleviate this problem, recent research has been focusing on frameworks to ease users’ authoring process as reconstruction and segmentation procedures, users find themselves with complete virtual objects, but no intrinsic behaviors have been seen in [9, 12, 35]. 3D scene reconstruction [32, 34, 44, 49] provides assigned, forcing them to use unfamiliar Desktop-based 3D editing a suitable solution to the problem. Initially a 3D reconstructed tools. AffordIt! offers an intuitive solution that allows a user to environment will be composed of a continuous mesh which can be segmented via autonomous tools as shown in George et al. [10] and select a region of interest for the mesh cutter tool, assign an intrinsic behavior and view an animation preview of their work. -

Plantuml Language Reference Guide (Version 1.2021.2)
Drawing UML with PlantUML PlantUML Language Reference Guide (Version 1.2021.2) PlantUML is a component that allows to quickly write : • Sequence diagram • Usecase diagram • Class diagram • Object diagram • Activity diagram • Component diagram • Deployment diagram • State diagram • Timing diagram The following non-UML diagrams are also supported: • JSON Data • YAML Data • Network diagram (nwdiag) • Wireframe graphical interface • Archimate diagram • Specification and Description Language (SDL) • Ditaa diagram • Gantt diagram • MindMap diagram • Work Breakdown Structure diagram • Mathematic with AsciiMath or JLaTeXMath notation • Entity Relationship diagram Diagrams are defined using a simple and intuitive language. 1 SEQUENCE DIAGRAM 1 Sequence Diagram 1.1 Basic examples The sequence -> is used to draw a message between two participants. Participants do not have to be explicitly declared. To have a dotted arrow, you use --> It is also possible to use <- and <--. That does not change the drawing, but may improve readability. Note that this is only true for sequence diagrams, rules are different for the other diagrams. @startuml Alice -> Bob: Authentication Request Bob --> Alice: Authentication Response Alice -> Bob: Another authentication Request Alice <-- Bob: Another authentication Response @enduml 1.2 Declaring participant If the keyword participant is used to declare a participant, more control on that participant is possible. The order of declaration will be the (default) order of display. Using these other keywords to declare participants -
UML Basics: the Component Diagram
English Sign in (or register) Technical topics Evaluation software Community Events UML basics: The component diagram Donald Bell ([email protected]), IT Architect, IBM Corporation Summary: from The Rational Edge: This article introduces the component diagram, a structure diagram within the new Unified Modeling Language 2.0 specification. Date: 15 Dec 2004 Level: Introductory Also available in: Chinese Vietnamese Activity: 259392 views Comments: 3 (View | Add comment - Sign in) Average rating (629 votes) Rate this article This is the next installment in a series of articles about the essential diagrams used within the Unified Modeling Language, or UML. In my previous article on the UML's class diagram, (The Rational Edge, September 2004), I described how the class diagram's notation set is the basis for all UML 2's structure diagrams. Continuing down the track of UML 2 structure diagrams, this article introduces the component diagram. The diagram's purpose The component diagram's main purpose is to show the structural relationships between the components of a system. In UML 1.1, a component represented implementation items, such as files and executables. Unfortunately, this conflicted with the more common use of the term component," which refers to things such as COM components. Over time and across successive releases of UML, the original UML meaning of components was mostly lost. UML 2 officially changes the essential meaning of the component concept; in UML 2, components are considered autonomous, encapsulated units within a system or subsystem that provide one or more interfaces. Although the UML 2 specification does not strictly state it, components are larger design units that represent things that will typically be implemented using replaceable" modules. -

In this thesis I will take a look at some examples of video games and how they made used of PCG. I also discuss how PCG can be defined and what mis- conceptions there might be. After this I will introduce a concept for a modular PCG workflow. The concept will be implemented as a Unity plugin called Velvet. This plugin will then be used to create a set of example applications showing what the system is capable of.

A Requirements Modeling Language for the Component Behavior of Cyber Physical Robotics Systems
A Requirements Modeling Language for the Component Behavior of Cyber Physical Robotics Systems Jan Oliver Ringert, Bernhard Rumpe, and Andreas Wortmann RWTH Aachen University, Software Engineering, Aachen, Germany {ringert,rumpe,wortmann}@se-rwth.de Abstract. Software development for robotics applications is a sophisticated en- deavor as robots are inherently complex. Explicit modeling of the architecture and behavior of robotics application yields many advantages to cope with this complexity by identifying and separating logically and physically independent components and by hierarchically structuring the system under development. On top of component and connector models we propose modeling the requirements on the behavior of robotics software components using I/O! automata [29]. This approach facilitates early simulation of requirements model, allows to subject these to formal analysis and to generate the software from them. In this paper, we introduce an extension of the architecture description language MontiArc to model the requirements on components with I/O! automata, which are defined in the spirit of Martin Glinz’ Statecharts for requirements modeling [10]. We fur- thermore present a case study based on a robotics application generated for the Lego NXT robotic platform. “In der Robotik dachte man vor 30 Jahren, dass man heute alles perfekt beherrschen würde”, Martin Glinz [38] 1 Introduction Robotics is a field of Cyber-Physical Systems (CPS) which yields complex challenges due to the variety of robots, their forms of use and the overwhelming complexity of the possible environments they have to operate in. Software development for robotics ap- plications is still at least as complex as it was 30 years ago: even a simple robot requires the integration of multiple distributed software components.
