A Ball, also known as Interface Realization or Provided Interface, in a Component Diagram represents an interface that a component implements or provides to other components. It indicates a service or capability that the component offers for use by other parts of the system.
With Balls in Modeldraw's Component Diagram, you can:
Show the services or capabilities that a component provides
Illustrate the public facing interfaces of a component
Demonstrate how components interact and offer functionality to each other
Clearly define the contract between components
Represent the modular and service-oriented nature of your system architecture
A Ball in Modeldraw's Component Diagram tool is typically represented by a small circle attached to the edge of a component. Key points to understand about Balls include:
Represents a service or capability offered by the component.
Other components can connect to this interface to use the provided service.
Defines a set of operations or functionalities that the component guarantees to provide.
Allows for hiding the internal implementation details of the component.
A component can have multiple balls, each representing a different provided interface.
Each ball should be named to indicate the nature of the service it provides.
To create a Ball in Modeldraw's Component Diagram:
Select the Ball (Interface Realization) tool from the toolbox.
Click on the component where you want to add the provided interface.
In the dialog that will show up select an interface.
The Ball will appear as a small circle on the component's border.
