![]() To see the list of methods, fields, and other code elements, select the appropriate icon on the diagram toolbar located on top of the diagram editor. You can press Ctrl+F12 on the element to view a list of diagram elements and navigate between them. Select VCS | Uncommitted Changes| Show Local Changes as UML Ctrl+Alt+Shift+D. You can view your VCS local changes as a diagram. IntelliJ IDEA generates a UML diagram for classes and their dependencies. In the list that opens, select Java Class Diagram. In the Project tool window, right-click a package for which you want to create a diagram and select Diagrams | Show Diagram Ctrl+Alt+Shift+U). Such diagrams always reflect the structure of actual classes and methods in your application. IntelliJ IDEA lets you generate a diagram on a package in your project. Open the Installed tab, find the Diagrams plugin, and select the checkbox next to the plugin name. Press Ctrl+Alt+S to open the IDE settings and select Plugins. If the relevant features aren't available, make sure that you didn't disable the plugin. This functionality relies on the Diagrams plugin, which is bundled and enabled in IntelliJ IDEA by default. Simply click the template to open it in the Creately editor to apply changes.UML class diagrams Enable the Diagrams plugin Component Diagram Examplesīelow are component diagram templates for common scenarios that you can instantly edit online. Step 5: You can attach notes on different parts of your component diagram to clarify certain details to others. to your component diagram and complete it. Step 4: Next step is to add other elements such as interfaces, classes, objects, dependencies etc. Step 3: As you draw the diagram, add components first, grouping them within other components as you see fit Step 2: As you figure out the relationships between the elements you identified earlier, create a mental layout of your component diagram in your system or application that you need to represent in your diagram. Step 1: figure out the purpose of the diagram and identify the artifacts such as the files, documents etc. Following are the steps you can follow when drawing a component diagram. It helps you get an idea of the implementation of the system. You can use a component diagram when you want to represent your system as components and want to show their interrelationships through interfaces. DependenciesĪlthough you can show more detail about the relationship between two components using the ball-and-socket notation (provided interface and required interface), you can just as well use a dependency arrow to show the relationship between two components. Port (represented by the small square at the end of a required interface or provided interface) is used when the component delegates the interfaces to an internal class. This shows that one component is providing the service that the other is requiring. The assembly connector allows linking the component’s required interface (represented with a semi-circle and a solid line) with the provided interface (represented with a circle and solid line) of another component. Interfaces in component diagrams show how components are wired together and interact with each other. Provided Interface and the Required Interface The component stereotype is usually used above the component name to avoid confusing the shape with a class icon.Ģ) Rectangle with the component icon in the top right corner and the name of the component.ģ) Rectangle with the component icon and the component stereotype. There are three ways the component symbol can be used.ġ) Rectangle with the component stereotype (the text >). ![]() We have explained below the common component diagram notations that are used to draw a component diagram. Help communicate and explain the functions of the system being built to stakeholders.Can be used to focus on the relationship between components while hiding specification detail.Are used in Component-Based-Development to describe systems with Service-Oriented-Architecture.The components can be a software component such as a database or user interface or a hardware component such as a circuit, microchip or device or a business unit such as supplier, payroll or shipping. They provide a high-level view of the components within a system. What is Component DiagramĬomponent diagrams are used to visualize the organization of system components and the dependency relationships between them. You can use a component diagram example below to get a quick start. In this component diagram tutorial, we will look at what a component diagram is, component diagram symbols, and how to draw one. While other UML diagrams, which describe the functionality of a system, component diagrams are used to model the components that help make those functionalities. ![]()
